A humidity sensor based on interpenetrating polymer network prepared from poly(dimethylaminoethyl methacrylate) and poly(glycidyl methacrylate)
چکیده انگلیسی

Humidity sensitive polymeric thin films with an interpenetrating network (IPN) structure were prepared by cross-linking reactions of poly(dimethylaminoethyl methacrylate) and poly(glycidyl methacrylate) with 1,4-dibromobutane (DBB) and diethyltriamine (DETA) as cross-linking agents, respectively. The humidity sensors so prepared showed a high sensitivity over a wide range of relative humidity (RH) (20–97%RH) and a small hysteresis (∼2%RH). The response time for adsorption and desorption process between 22 and 84%RH was 4 and 20 s, respectively, indicating a fast response. The effects of the concentration of polymers, molar ratio of cross-linking agents and polymers and aging time of the precursor solution for dip-coating on their humidity sensitive properties were investigated.
