Abstract
Poly(1H,1H,2H,2H-perfluorodecyl acrylate) (PPFDA) is incorporated within a sintered mesoporous network of TiO2 nanoparticles via initiated chemical vapor deposition (iCVD). iCVD PPFDA grows uniformly on the pore surface of the mesoporous TiO2 (25 nm pore diameter, 2-4 mu m thick), resulting in up to 91% of the pore volume being filled. This leads to a high TiO2 loading (58 vol %, 67 wt %) in the PPFDA TiO2 nanocomposite and a large decrease in the PPFDA crystallinity by >93% compared to the bulk polymer film. The significantly suppressed crystallinity is attributed to the nanoconfinement of polymer chains in the tortuous, interconnected nanopore channels that frustrates chain alignment, and from the large interfacial energy difference between PPFDA fluoropolymer and hydroxylated TiO2 that impedes heterogeneous nucleation for crystal growth.
