利用氩氧混合低能离子束对双酚A型聚碳酸酯(PC)透明材料进行表面改性,并用自制丙烯酸酯胶黏剂表征了改性前后的粘接性能.结果表明:改性后的PC与丙烯酸酯胶黏剂的压剪强度得到了明显的改善.经分析,粘接性能的改善是由于低能离子束表面改性后的PC表面润湿性能的改善、表面活性的提高、表面弱电层的剥蚀和表面微交联层的生成引起的.
Ar/oxygen ion beam generated in gridless ion beam source with low energy was employed for surface modification of polycarbonate (PC) aimed at improvement of its adhesion characteristics. The results showed that the adhesion characteristic between PC and acrylate adhesive was significantly improved after modification because of ion beam bombardment resulted in excellent hydrophilicity,increasing of the polarity,denuding of the weak boundary and engendering of crosslinked boundary.
