Nanesa - Nanomaterials, conductive pastes and Hexagonal allotropic compounds

Information sheet for the use of Nanesa nanometric products

According to the client’s needs, the family of G2Nan products can be provided both in the form of powder or dispersed in liquid or paste–based solvents depending on concentration, or in polymeric matrices.



G2Nan in powder:


This is a partially volatile powder with a very low bulk density (~ 0.030 g/cm3).

The class of G2Nan materials can be provided in the form of dehydrated granules. These compact shapes are crumbly and revert to the original powdered form by a simple mechanical shaking before use.



G2Nan dispersed in solvents


- Organic solvents

All the materials of G2Nan family can be dispersed in organic solvents such as NMP (N- methylpyrrolidone), DMF (Dimethylformamide), THF (Tetrahydrofuran), MEK (Methyl ethyl ketone), Toluene, Ethanol, Acetone and in other organic solvents, according to final use.


- Aqueous solvents

All the materials of G2Nan family can be dispersed in aqueous solvents even with the aid of dispersing agents or surfactants: SDBS (sodium dodecylbenzene sulfonate), PSS (Poly-sodium styrene sulfonate), PVP (Polyvinylpyrrolidone).

Particles that sediment can be rapidly re-dispersed simply by shaking or by using ultrasounds.



G2Nan dispersed in polymers


- Thermo-hardening resins

All the materials of G2Nan family can be directly dispersed in resins.


- Thermoplastic polymers

All the materials of G2Nan family can be directly dispersed in powdered polymer with the aid of a blender and a suitable dosage system.



GONan


Nanesa Graphene Oxide (GONan) can be offered dry or dispersed in a liquid.


- GONan in flakes: in the form of flakes or sheets, it can be re-dispersed in water by using ultrasounds.


- GONan in aqueous solution: in aqueous solution it creates a stable colloidal dispersion. The highest concentrations reach the 10% (in weight).


- GONan in organic solvents: it can be dispersed in organic solvents such as Ethanol, Acetone, DMF, THF, MEK with the help of ultrasounds.
