The investigation was made on wettability of polymer surfaces. In general, the wettability of polymer surface is influenced by the conditions under which the polymer is solidified from the solution. It is of interest to examine the effect of substrate contacted with polymer during the process of solidification on the wettability of the polymers.
In this study, the substrata adopted for PAN were aluminium oxide (Al₂O₃), polyethylene (PE), polytetrafluoroethlene (PTFE). For P (AN-St) and PAN/PSt were Al₂O₃. Wettability for polymer surface was determined in the same manner as our previous paper. (This journal 32, T145 (1976)).
Results are as follows:
1) In the case of PAN film which was composed of mono-component, the surface wettabilities were influenced only slightly by the kind of substrate.
2) In regard to multi-component polymer such as P (AN-St) and PAN/PSt, the influences of substrate were recognized in their wettabilities; the wettability of Air-side of film decreased with the increasing content of St, while Al₂O₃-side of film was changed slightly. This fact may be explained by the conception of “Induced Orientation” of polymer. And the differences between Air-side and Al₂O₃ were shown in the case of blendpolymer more remarkably than in the case of copolymer.
