Abstract

In this study, the effect of plasma treatment on glass-cloth-containing polytetrafluoroethylene (GC-PTFE) was investigated. Previous plasma studies investigated pure PTFE (which does not contain glass cloth) but not GC-PTFE. The effect of Ar + HO plasma treatment on GC-PTFE was investigated. The Ar + HO plasma-treated GC-PTFE sheets were thermally compressed to stainless steel (SUS304) foils without using adhesive, and the GC-PTFE/SUS304 adhesion strengths were measured using a 90° peel test. The adhesion strength increased with the increase in the plasma treatment time (0.8 and 1.0 N/mm at 20 s and 300 s, respectively). Thus, strong adhesion between GC-PTFE/SUS304 was achieved without adhesive. This improvement in the adhesion properties of GC-PTFE can be attributed to the generation of oxygen-containing functional groups and the decrease in the surface roughness of the samples. Thereafter, the adhesion properties of GC-PTFE and pure PTFE were compared. Because, unlike pure PTFE, GC-PTFE has no weak boundary layer, GC-PTFE exhibited better adhesion properties than pure PTFE under short plasma treatment times.

摘要

在本研究中,研究了等离子体处理对含玻璃布的聚四氟乙烯(GC-PTFE)的影响。以往的等离子体研究针对的是纯聚四氟乙烯(不含玻璃布),而非GC-PTFE。研究了Ar + HO等离子体处理对GC-PTFE的影响。将经Ar + HO等离子体处理的GC-PTFE片材在不使用粘合剂的情况下热压到不锈钢(SUS304)箔上,并使用90°剥离试验测量GC-PTFE/SUS304的粘合强度。粘合强度随等离子体处理时间的增加而增加(分别在20秒和300秒时为0.8和1.0 N/mm)。因此,在不使用粘合剂的情况下实现了GC-PTFE/SUS304之间的强粘合。GC-PTFE粘合性能的这种改善可归因于含氧官能团的产生以及样品表面粗糙度的降低。此后,比较了GC-PTFE和纯PTFE的粘合性能。由于与纯PTFE不同,GC-PTFE没有弱边界层,因此在短等离子体处理时间下,GC-PTFE表现出比纯PTFE更好的粘合性能。
