✦ Synopsis

Polyaniline/crosslinked cellulose conductive interpenetrating polymer networks (IPNs) were prepared by oxidative polymerization of aniline within the self-synthesized cellulose network using ammonium persulphate as oxidant. The conductivity of the IPN increases and then decreases with decrease in the ratio, with increase in the HCl/aniline ratio, with increase in aniline/(NH 4 ) 2 S 2 O 8 aniline content, as well as with increase in reaction time. In addition, the conductivity of the Ðlms strongly depends on the amount of tetraethyl orthosilicate crosslinker. In comparison with polyaniline/cellulose acetate composites, the conductivity increases by an order of one to two magnitudes in spite of the lower polyaniline content in this work.
