摘要
研究了具有优异耐热性的聚酰亚胺胶黏剂对聚四氟乙烯微孔薄膜的粘接性能。结果表明,聚酰亚胺胶黏剂对未经表面改性的聚四氟乙烯微孔薄膜没有粘接能力。采用钠萘溶液、N_2和O_2等离子体处理后,聚四氟乙烯微孔薄膜亲水性增强,聚酰亚胺胶黏剂都可以获得不同程度的粘接能力。但不同的处理方法,同等的亲水性条件下,粘接能力有一定的差异。钠萘溶液改性处理时,只有在接触角小于90°的情况下才可以明显改善薄膜的粘接性能。在亲水性90°～120°范围内,等离子处理的粘接效果要好于钠萘处理的情况。
The adhesive performance of polyimide based binder, which had excellent heat resistance, to PTFE microporous membrane was studied. The results showed the binder had no adhesive power to the PTFE micropore membrane which was not surface modified. When Na-Naphthalene solution, O2 and N2 plasma were used to the hydrophilic modification of the PTTE micropore membrane, the binder would have adhesive power to the membrane in varying degrees. When the modification methods were different, the adhesive power could be different by the same hydrophilicity. As to the Na-Naphthalene solution treatment, only when the contact angle was smaller than 90°, the adhesive property of the membrane could be improved. When the contact angles were in the range of 90°to 120°, the adhesive result by plasma treatment was better than that by Na-Naphthalene solution treatment.
