摘要：

A novel silicone-containing polyelectrolyte (Si-PE) with crosslinked network was prepared by radical copolymerization to obtain a better humidity sensing material. The sensors based on Si-PE prepared with different proportion of the comonomer all exhibited high sensitivity to humidity variation over a wide range of relative humidity (11-96%RH). Their humidity sensitive properties have been investigated. The sensors exhibit very fast response (about 4 s) to an abrupt humidity change (97 and 33%RH). (c) 2005 Elsevier B.V.
