Electron beam irradiated natural Rubber-Polyaniline dodecylbenzenesulphonate blends: Their preparation,Electrical and physical properties

Electron beam irradiation technique was successfully used for the first time in order to crosslink the natural rubber-polyaniline dodecylbenzenesulphonate [nr-pani. dbsa] blends. significant increases in crosslink densities of all blends with doses of irradiation up to 200 kgy were obtained and a reasonably high crosslink density level (in the order of 10 4 mol/cm3) was achieved. all electron beam-irradiated nr-pani.dbsa blends showed good tensile properties with tensile strength up to about 19.7 mpa. this kind of irradiation induced-crosslink technique at doses up to 200 kgy also did not affect electrical properties after being sufficiently stabilised for at least 24 hours. the irradiated nr-pani.dbsa blends also exhibited good electrical properties,i.e. a single conductivity percolation threshold and high conductivities up to the order of l0-2 s.cm -1. in other words,there is a good potential of using electron beam irradiation technique to prepare highly crosslinked,electrically conductive nr-pani.dbsa blends.
