Fluorinated Polymer Films: Synthesis And Characterization, Anja Ulrike Schnurer
Dissertations and Theses
Three polyfluoroalkyl epoxides, (I OCH2CHCH2OCF2CF2SO2F, II OCH2CHCH2(CF2)8F and III OCH2CHCH2O(CF2)CF(CF3)SO2F) were photopolymerized with a cycloaliphatic diepoxide (Cyracure UVR-6110) to form highly crosslinked glassy films. Depth-dependent surface analysis with XPS show that these films are highly enriched with sulfonyl fluoride groups in the outer molecular surface. Film compositions of 17 % wt and more of the fluorinated I and III show surface characteristics of a film composed of 100 % wt of the …
