摘要:以聚丙烯酰胺(PAM)水凝胶为基体、甘油(Gly)为保湿因子、LiCl为吸水因子,通过盐溶液浸渍法制备PAM-Gly-LiCl水凝胶。通过扫描电镜、能谱仪、X射线光电子能谱仪、傅里叶红外光谱仪等对该水凝胶结构及性能进行表征,同时探究其应用于便携式雪茄保湿袋对微环境湿度的调控效果。结果表明:PAM-Gly-LiCl水凝胶具有优异的透明性和力学性能,透光率可达90%,最大压缩应变可达41%,压缩强度为1.1 MPa,断裂伸长率可达1100%,断裂强度为0.25 MPa;该水凝胶还具有优异的保水与调湿性能,拥有较高结合水比例的同时,可稳定实现不同湿度环境条件下的调湿过程,调湿区间为相对湿度25%~95%并持续500 h。将其应用于便携式雪茄保湿袋中,能够快速感知环境湿度变化,并作出智能响应,将袋内微环境湿度稳定在相对湿度65%左右并保持一周以上。

Abstract:Polyacrylamide (PAM)-glycerol (Gly)-lithium chloride (LiCl) hydrogel was prepared by salt solution immersion method, using PAM as the hydrogel matrix, Gly as the moisturizing factor and LiCl as the water absorption factor. The structure and performance of the hydrogel were characterized by scanning electron microscope, energy dispersive spectrometer, X-ray photoelectron spectrometer, Fourier infrared spectrometer, etc. Meanwhile, the effect of its application in a portable cigar moisturizing bag on the regulation of micro environment humidity was explored. The results showed that the PAM-Gly-LiCl hydrogel possessed excellent transparency and mechanical properties, with light transmittance of 90%, the maximum compression strain of 41%, compression strength of 1.1 MPa, elongation breaking rate of 1100% and breaking strength of 0.25 MPa. The hydrogel also displayed excellent water retention and humidity control performance. Owing to a high proportion of combined water, it could stably realize the humidity control process under different humidity environmental conditions. The humidity control range was 25%~95% of the relative humidity and kept for 500 h. The hydrogel could be applied to design as a portable cigar moisturizing bag. It could quickly sense changes in environmental humidity and make intelligent responses, stabilizing the microenvironment relative humidity inside the bag at around 65% and maintaining it for more than a week.
