Materials Acceptable for Application in Humidity Sensors

Porous dielectric ceramics (capacitance type) Porous semiconductors (capacitance type) Other materials [Pg.392]

Polyelectrolytes (quaternary ammonium salts, sulfonate salts, and phosphonium salts) KOH-H O-doped PVA poly(/ -diethynylben-zene) or PDEB poly(proptugyl benzoate) (PPBT) p-diethynylben-ziene-co-propatgyl alcohol ethynylbenzone-co-propaigyl alcohol (copolymer) polymethyl methacrylate, etc. [Pg.392]

Polyimides polyethersulfone (PES) polysulfone (PSE) divinyl sUoxane benzoqrclobutene (BCB) cellulose acetate butyrate (CAB) hexamethyldisilazane (HMDSN) poly(methyl methacrylate) (PMMA) poly(vinyl cinneunate) [Pg.392]

MultiwaUed carbon nanotube (MWCNT) carbon nitride CNx phthalocyanines [Pg.392]

Experiment has shown that cellulose acetate (CA) or cellulose acetate butyrate (CAB) can also be used for these purposes (Sakai et al. 1996 Yang et al. 2006). However, many problems such as hysteresis, stability at high humidities and at high temperature, and durability on exposure to some kinds of organic vapors still remain to be solved. Sadaoka et al. (1988) also established that the hysteresis for the various cellulose derivatives-based sensors was caused by the formation of clusters of sorbed water molecules. [Pg.395]
