摘　　要：利用一种自制的新型聚酰亚胺作为感湿材料,选择适当的亚胺化条件和电极制备方法制得湿敏电容,并对其进行了响应时间、灵敏度、温度系数、湿滞、非线性误差和湿度量程以及长期稳定性等一系列研究。各项研究结果表明:制得的湿敏电容综合性能良好,有望应用于湿度传感器领域。A self-made polyimide was used as the humidity sensitive material to obtain humidity sensitive capacity under appropriate imidization conditions by electrode preparation method. A series of properties including response time, sensitivity, temperature coefficient, wet hysteresis, nonlinearity error, humidity range and long-term stability were studied. The results showed that the humidity sensitive capacity had good performances and could be used in the field of humidity sensors.
