医疗电极用光固化压敏导电胶的研制

Development of UV-Cured Pressure-Sensitive Electrically-Conductive Adhesives for Medical Electrodes

以丙烯酸和丙烯酸酯为单体、多官能丙烯酸酯为交联剂、安息香醚为光引发剂，利用光聚合手段研制成一种新型压敏导电胶电极。探讨了影响压敏导电胶性能的因素。发现光引发剂的最佳用量为质量分数０．５％；轻度交联和采用极性单体共聚，可有效改善压敏胶粘性能；共聚物中的丙烯酸的中和度增大，可提高电性能。

A new type of pressure-sensitive electrically-conductive adhesive electrode was developed by photopolymerization, using acrylic acid and acrylate as monomer,muitifunctional acrylate as crosslinking agent, benzoin ethers as photoinitiator.Different factors that affect the properties of the pressure-sensitive electricaly-eonductive adhesives were examined.t was found that the proper mass fraction of photoinitiator is 0.5%,the properties of pxessure-sensitive adhesives can be improved by partially crosslinking and copolymerizing with polar monomers,and that the elcctrical properties can be raised by increasing neutralization degree of acrylic acid in lhe copolymer.
