Abstract: The nano-polyaniline/epoxy acrylate (PANI-DBSA/EA) mixture was synthesized by in-situ emulsion polymerization.Then it was added that diluted crosslinking monomer and initiating agent with stirring until well-distributed.At last,PANI-DBSA/EA interpenetrating networks conductive film was prepared through UV curing.The influence of crosslinking monomer,initiator,cure time and PANI-DBSA to the film's gel content and conductivity was investigated.The results showed that the gel content of film reached 91.8% and the conductivity was 8×10-6S/m when the content of PANI-DBSA was 15wt%,the initiating agent dosage of TPO was 4wt%,the content of crosslinking monomer EO-TMPTA was 50wt% and the curing time was 40s.
