【摘要】 以物理化学中的吸附理论为出发点,探讨高分子材料的感湿机理,研究了高分子湿敏材料的微观结构与灵敏度、湿滞、温度系数、长期稳定性等性能指标的内在联系,结合理论分析和实践提出了电容式高分子湿敏材料的功能设计方法,选取聚酰亚胺和制作的敏感元件对该理论进行验证,实验结果表明该方法有很强的可操作性。更多还原

【Abstract】 The humidity sensitive principle of polymer based on absorption theory in physical chemistry was discussed.Relations of microstructure and performance such as sensitivity,hyster- esis,temperature coefficient,long term stability were investigated.The method of function de- sign on capacitive humidity sensitive polymer was given based on theory and practice.The result of experiment indicates maneuverability of this method by sense organ made from PI.更多还原
