Electron beam irradiated natural rubber-polyaniline dodecylbenzenesulphonate blends: their preparation electrical and physical properties

Yong K. C., . Electron beam irradiated natural rubber-polyaniline dodecylbenzenesulphonate blends: their preparation electrical and physical properties. pp. 1-14. ISSN 1511-1768

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 104 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 10“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.

Abstract

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 104 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 10“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.
