Abstract
Two procedures allowing grafting of an axially functionalized silicon phthalocyanine dichloride across the surface of a dehydrofluorinated polyvinylidene fluoride (PVDF) film surface are presented. In the first method, a PDVF surface was initially dehydrofluorinated by an alkaline degradation process, followed by grafting of a phthalocyanine moiety across the conjugated surface in the presence of a platinic acid catalyst. In the second, one-step sonication method, the use of a lithium coupling agent was employed. UV-VIS, ATR FT-IR, and XPS spectroscopies was used to characterize the nature of surface bonding and the extent of surface reactions.
