摘要：

Waste paper of postcards was used for the fabrication of woodceramics (WCMs). The electrical impedance and humidity sensitivity were measured. The impedance for WCMs fabricated from the waste paper (WP-WCMs) decreased with the increase of annealing time at 620 degrees C and the impedance of WCMs mixed with 40% phenolic resin was smaller than that of WCMs mixed with 30% phenolic resin. The WP-WCMs had higher quality than WCMs fabricated from medium density fiberboard (MDF-WCMs). In addition, the humidity sensitivity was twice as large as that of MDF-WCMs, because the density of WP-WCMs was smaller than that of MDF-WCMs and the specific surface area of WP-WCMs was larger than that of MDF-WCMs. Consequently, waste paper of postcards is suitable raw material for WCMs humidity sensor.
