Efficient infiltration of low molecular weight polymer in nanoporous TiO2

The polymer APFO3 was prepd. with different mol. wts. to study how the infiltration into nanoporous TiO2 films of different thickness depends on the size of the polymer. Also two different sizes of TiO2 nanoparticles were investigated to understand the effect of different pore size. It was obsd. that the lowest mol. wt. polymer dissolved in chlorobenzene could infiltrate the nanoporous TiO2 network up to several micrometer thick films. It was concluded that efficient polymer infiltration into thick nanoporous layers was possible for the polymers with an estd. av. chain length smaller than the diam. of the nanoparticles.
