Opis:: The nanocomposite material based on chitosan was obtained and characterized. Commercially produced biopolymer at 85% deacetylization degree was used. The biopolymer matrix was modified with carbon nanofillers such as graphite oxide (GO), carbon nanotubes (CNTs) and nanontubes with the surface affected by carboxyl groups (CNT-COOH). The obtained nanocomposites were formed by means of two methods: casting (to manufacture nanocomposite foils) and liofilization (to manufacture porous nanocomposite materials). Their electrical properties and microstructure were examined. The tests proved that adding the carbon nano-filler results in high resistivity (graphite foils, carbon nanotubes) and also the average size of pores in liofilized materials. Additionally, the electric potential of the materials may be improved by surface processing (EPD- electrophoretic deposition). The described materials are an alternative to polymer nerve implants e.g. tubes or hydrogels which are already present on the market and applied to regenerate nerves.

Opis:: The aim of this work was to examine composite membranes obtained by means of phase inversion from a synthetic stable polymer – polyvinylidene difluoride (PVDF). The piezoelectric polymer was modified with 0.5-1wt% addition of commercial carbon fillers: graphite oxide (GO, 1wt%), multiwalled carbon nanotubes (CNT, 1wt%) and functionalized nanotubes (CNT-COOH, 0.5wt%). The membranes were obtained by solidification of nanocomposite solutions in coagulation bath (CH3OH). The obtained series of materials differed in surface porosity (P), electric conductivity (σ) and surface free energy (SFE). It was proved that presence of carbon nanoadditive influenced microstructure of the membranes: the mean size of pores in the membrane rose in the following order: GO→CNT→CNT-COOH. The very same system depicted the influence of the filler on the membrane structure: the increase in membrane crystallinity (λ) and the β phase share (FT Raman). From all the examined nanocomposite systems, the PVDF modified with 0.5wt% CNT-COOH displayed the most advantageous electric properties. These nanocomposite membrane (PVDF/CNT-COOH) could be used as a low-voltage electrodes in biomedical application. Yet, taking into account the other physicochemical, mechanical and structural properties, the membranes modified with 1wt% CNT and 1wt% GO were also interesting.
