The application fields of polymer-based and composite materialshave been expanding. These materials are replacing conventional structural and functional materials in various industries: chemical, nuclear, aerospace, electronics, consumer goods, energy, shipbuilding, anti-corrosion systems, transport, construction and infrastructure, etc.
Approaches being developed to obtain nanomodified polymer-based and composite materials will be widely employedin distributing of a solid nanodispersed fraction in the bulk of ahighly viscous binder,since they allow for improvement of the cumulative physical and mechanical characteristics to a level that is unattainable with traditional approaches.
The nanomodification improves the properties of most polymers (both thermoplastics and duroplastics).The addition of 0.01-1 wt.% (Fig. 12.) of CNTs significantly increases their strength as well as crack and water resistance, and besides, the properties atypical for polymers – electrical and thermal conductivity – are acquired. The introduction of CNTs into epoxy matrix reduces its resistance from 108 down to 2.5 Ohm m. The strength of hardened epoxy resin increases by 20-30%, and the elasticity of composites on its basis increases several times. Masterbatches containing 12 wt.% of CNTs (Fig.) maintain stability during one year of storage.
