| 摘 要： | 尝试以聚四氟乙烯（PTFE）乳液为原料制备PTFE微孔膜，选定化学稳定性、热稳定性优异的纳米二氧化锆（ZrO2）作为增强剂以提高微孔膜强度，采用电子万能力学试验机测试了样品的力学强度，用单因素法讨论了纳米ZrO2含量、拉伸比例、热处理温度和热处理时间对微孔膜拉伸强度的影响；同时采用低温等离子体处理PTFE/ZrO2复合微孔膜以改善其表面亲水性。结果表明，PTFE/ZrO2复合微孔膜的拉伸强度与纳米ZrO2含量成正比，与拉伸倍数成反比；其拉伸强度随着热处理温度的升高或热处理时间的延长，呈先增大后减小的变化趋势，分别在310 ℃和10 min时出现最大值；低温等离子体处理的最佳时间为30 s。

| Abstract: | This paper used polytetrafluoroethylene(PTFE) emulsion as a matrix phase,micro-nanozirconium dioxide(ZrO2) powder as a reinforcer to prepare PTFE/ZrO2 composite membranes via mechanical stretch,and the tensile strength of the membranes was tested.Single-factor method was used to analyze the effect of ZrO2 powder content,draw ratio,heat-treatment temperature,and heat-treatment time on the tensile strength of the composite membrane.PTFE/ZrO2 membranes were post-treated by low-temperature plasma to study the e... |
