摘要:
采用涂层法制备聚偏氟乙烯(PVDF)/氯化钴(CoCl2)/棉织物(Cotton)湿敏材料,将PVDF和CoCl2的N,N-二甲基甲酰胺混合溶液均匀涂覆在棉织物上,得到PVDF/CoCl2/Cotton湿敏材料,用同样方法制备CoCl2/Cotton和聚丙烯腈(PAN)/CoCl2/Cotton的湿敏材料(作为对照组)。利用界/表面张力仪、傅里叶红外光谱仪和可见光分光光度计对湿敏材料进行物理化学性能测试。结果表明:30 s后水滴在PVDF/CoCl2/Cotton湿敏材料的表面接触角为102°,证明该材料具有优异的防水性能; 当湿度从11%增长到98%时,湿敏材料的颜色由蓝色向粉色转变,该颜色的转变可以用肉眼直接观测,不需要使用任何检测仪器。PVDF/CoCl2/Cotton湿敏材料在不同湿度下的颜色差异主要是因CoCl2吸收或失去结晶水所致。
Abstract:
The humidity sensing material of polyvinylidene fluoride/cobalt chloride/cotton fabric(PVDF/CoCl2/Cotton)with waterproof property was prepared by coating method,and its colorimetric humidity sensing property was characterized. Specifically,PVDF/CoCl2/Cotton humidity sensing material was obtained by uniformly coating the mixed solution of PVDF/CoCl2/N,N-dimethylformamide on the surface of cotton fabrics. In addition,the humidity sensing materials of CoCl2/Cotton and PAN/CoCl2/cotton were also prepared with the same method. The physicochemical properties of the humidity sensing materials were characterized through boundary/surface tensiometer,Fourier tranform infrared spectrometer(FTIR)and visible light spectrophotometer. The results demonstrated that the contact angle of water droplets on the surface of PVDF/CoCl2/Cotton after 30 s was 102°,which proved that the material had excellent waterproof performance. As the humidity increases from 11% to 98%,the color of the PVDF/CoCl2/Cotton humidity sensing material changes from blue to pink. The change of colors can be directly observed by the naked eye without the use of any detection equipment. The different colors of PVDF/CoCl2/Cotton humidity sensing material under different relative humidity are mainly caused by the absorption or loss of crystal water of CoCl2.
