2 Introduction graphenit is a series of chemically modified graphite nano-platelets for the industrial market. This product has been created by Nanoinnova Technologies SL and represents a unique offer with a series of raw graphene derivatives in powder and in concentrated dispersion format, paving the way to introduce this extraordinary material in many industrial processes. What is graphene? Graphene is a single carbon 2D layer. This new material was isolated and characterized in 2004 for the first time. In 2010 Prof. Geim and Novoselov were granted with the Nobel Price for this discovery. The properties of graphene at nanoscale dimension (10-9 m, times less that a human hair) are extraordinaries: stronger than steel, more electrically and thermally conductive than copper, impermeable to gases, highly flexible, etc. But graphene requires a surrounding macroscopic matrix to be applied. The dispersion process represents the higher barrier for market introduction. What is Graphite Nano Platelets? Graphite can be defined as millions of single carbon layers (graphene). In fact it is estimated that a graphite flake contains 3 million layers of graphene. During the past decade since the isolation of graphene the technology to exfoliate graphite to low dimensional carbon nanoflakes allowed the mass production of few layer (less than 5 to 10 layers) of nano graphite named GRAPHITE NANOPLATELETS, GRAPHENE NANOPLATELETS or GNPs. -1- Chemically Modifed Graphene Nano Platelets. What s for? Graphene nanoplatelets are pure carbon very lipophilic, with a high tendency to aggregate and poor interactions with the surrounding matrix, hence difficult to disperse in industrial processes and supports such as epoxy resin, thermoplastics or solvents such as water. The chemical modification on the surface of graphite nanoplatelet open new properties allowing good interaction with the targeted matrix. Without these chemical modifications the dispersion step became a difficult task and quite often do not produce the expected benefits. graphenit is presented not only as raw powder material, but in concentrated formats in water or epoxy resin components, speeding up the incorporation to the eventual industrial process.

3 -2- Introduction The technology to incorporate graphenit to end user markets are based on the graphite exfoliation followed by a chemical functionalization step that configures the identity of the graphenit raw material. Therefore lateral size, number of layers and chemical functionalization yields the 3 fundamental parameters to define every graphenit. With the spirit to facilitate the incorporation to industrial processes we had developed the technology to produce masterbatches allowing a better dispersion into the target matrix. In collaboration with strategic partners we offer too R&D services facilitating end user product development.

14 GRAPHENIT DISPERSIONS IN THERMOSETTING POLYMERS Graphene NanoPlatelets in thermosetting polymers showed a great potential in industrial applications. Reaching a good dispersion is the cornerstone for achieving better properties with low percentages of loading. It is well known that Graphene NanoPlatelets dispersion in thermosetting resins such as epoxy or polyurethane, etc requires high shearing methodologies for an appropriate process. Three roll mill technology has been used with success in the literature and represents an extraordinary asset in composites, coatings and high viscous matrices. In Nanoinnova Technologies we offer a full dispersion service of graphenit derivatives from basic resin dispersion to detailed microscopic analysis by SEM of the target composite for a comprehensive optimization of the whole application process of thermosetting resins. -13-

20 ANTI-CORROSION IUPAC defines corrosion as an irreversible interfacial reaction of a material (metal, ceramic and polymer) with its environment which results in consumption of the material Only in US it is estimated a cost of 200$ billion/year because of corrosion. Anti-corrosion coating protection can be divided into three mechanisms: barrier creation between substrate and environment (PASSIVE); inhibition of the corrosion processes and sacrificial material (ACTIVE). Heavy metals such as Cr, Zn, etc has been used in the industry for decades as anti corrosive agents. The search of more environmentally friendly additives to prevent corrosion represents an unique opportunity. graphenit, a series of chemically modified graphite nano-platelets for industrial applications, represents a sustainable alternative (only carbon, no heavy metals). The flake shape and the well known gas barrier properties of graphene makes an ideal case for passive protection but the chemically modified capability of graphenit technology enlarges the possibilities to active protection mechanisms too. The good dispersion capabilities in polymeric matrix such as epoxy resin, commonly used in the coating industry, facilitates its application. graphenit-ox has been used with success in the powder coating industry. As little as 0,75% in coating composition shows an improvement of 50% in the fog saline chamber assay performance (from 600 hours of the primer to 900 hours to the primer+ 0.75% graphenit-ox) and double the resistance in the accelerated AC/DC/AC impedance test. The accelerated EIS electrochemical assay shows the importance to optimize the concentration of this nano material in the coating: 2,5% loading performs worse than 0,75%. Aggregation is at the base of this result and has to be considered case by case. -19-

21 ANTI-CORROSION Atmospheric corrosion proceeds by balanced anodic and cathodic reactions. The anodic oxidation reaction involves the corrosion attack of the metal, while the cathodic reaction is the oxygen reduction reaction as shown in the following redox equation. Anode Reaction 2Fe 2Fe e - Cathode Reaction O H 2 O + 4e - 4OH - Corrosion Rate (CR) could be calculated from Tafel plots by polarization experiments using a standard procedure ASTM G56. We observed that graphenit-ac is an excellent additive for slowing down the oxidation of steel in saline conditions. Epoxy primer (Primer 2) in the chart/table and Graphenit-AC 1% (Primer 2 + 1% of graphenit-ac dispersed for powder coating) shows a clear improvement. Corrosion Rate CR of Graphenit-AC1% is 0, mm/year face to 0,00271 mm/year of the primer and 0,012 mm/year of the steel substrate. This data is in agreement with the fog saline test. -20-

22 graphenit is a trade mark registered by Nanoinnova Technologies SL VAT= ESB Calle Faraday 7, Madrid (SPAIN) -21- CEMENT/CONCRETE DURABILITY Graphene, a single layer sp2 carbon nanomaterial, is known to be an extraordinary electrical conductor with a conductivity in the order of 105 S m-1 of the pristine material. Although polymers exhibit very high surface resistivity (>1016 Ω/sq), it is known that graphene, used as a nano-filler in low concentrations, is able to yield to conductive/antistatic composite polymers. However, a good dispersability in the polymeric matrix is critical for a low percolation concentration. graphenit, a series of chemically modified graphite nano-platelets for industrial applications, represents a sustainable alternative (only carbon, no heavy metals) for transforming isolating polymer matrix in electrical conductive/dissipative material. Durability of cement/mortar (ability to resist weathering action, chemical attack, abrasion, or any process of deterioration) correlates with its porosity. graphenit has been successfully used for significant reduction of cement porosity. For 28 days samples it shows the cumulative volume of the pores, intruded by mercury (MIP). It is seen that the total porosity of the paste containing graphenit is less than the pure cement pastes (without graphenit). For the HW-0.01% the total porosity has reduced from 30% (for 0% graphenit) to 15%. Paste ID Cement (g) Water (g) graphenit Paste (g) graphenit /cement % 100%PC HW
