Abstract
Initiated chemical vapor deposition (iCVD) enables the uniform growth of polyglycidol (PGL) within mesoporous layers of TiO2 nanoparticle networks. Through the cationic ring opening polymerization of glycidol, conformal deposition of PGL by iCVD results in up to 91% of the available pore space being filled. This yields polymer nanocomposites with high nanoparticle loading of 82 wt% and 54 vol%. The glass transition of the PGL nanocomposite is found to increase significantly by 50 degrees C-60 degrees C compared to the bulk PGL polymer. This marked temperature rise has been attributed to significant hydrogen bonding interaction of the oxygen and hydroxyl groups in the polymer with the hydroxyl groups on the surface of the TiO2 nanoparticles. Such interactions under polymer confinement are only possible as a result of the tight integration of the polymer and inorganic materials afforded by the iCVD approach.
