Conteúdo: |
Blends possessing lhe elastomeric properties of natural rubber (NR) and the conducting properties of conducting polymer (polyaniline, PANI) were obtained, which are promising for further application in deformation sensors. Blends containing 20% (v/v) of PANI in 80% of NR latex were fabricated by casting in the form of free-standing films and treated either with H Cl or with carona discharge, which lead P ANI to its conducting state (doping process). Characterlzation was carried out by Raman spectroscopy, d.c. conductivity and thermogravimetric analysis. Evidence for chemical interaction between PANI and NR was observed, which allowed lhe conclusion that lhe NR latex itself is able partially to induce both the primary doping of PANI (by protonation) and lhe secondary doping of PANI (by changing the chain conformation). Further improvement in the primary doping could be obtained for lhe blends either by carona discharge or by exposing them to HCI. The electrical conductivity reached in lhe blends was dependent on the doping conditions used, as observed by Raman scattering. |
