Probing the mechanism of water vapour ingress into polyimide films used in ca...

We are seeking to determine how far, and over what timescale, water vapour penetrates the layered polymer/thin-film metal structures used in capacitance type humidity sensors....本研究旨在探明水蒸气在电容式湿度传感器所采用的层状聚合物/薄膜金属结构中的渗透深度与对应的时间尺度……
