摘要
以国产材料(A)和日本进口材料(B)合成的高分子材料作感湿膜,制作了高分子湿敏器件,均具有良好的感湿特性。增涂乙基纤维素保护膜,有使(A)器件湿滞回差变大,(B)器件湿滞回差变小的趋势。浸水时间不当均可使两种器件的湿滞回差变大,因此合理控制浸水时间是必要的。
Humidity-sensitive sensors were fabricated with the high polymer films composed of Chinese material (A) or Japanese raw material respectively。When protecting film coated with ethyl cellulose, hysteresis of sensors (A) decreases; that of sensors (B) increases. When soaked in water for too long or too short time,hysteresis of both sensors(A) and sensor (B) may increase. Therefore, it is important to carefully control time when they are soaked in water.
