Organic-inorganic (O-I) hybrid nanoparticles could be prepared using an alkoxysilane-functionalized amphiphilic polymer (AFAP) precursor consisting of reactive alkoxysilane groups and amphiphilic polymer backbone. O-I hybrid sols having long-term storage stability with 40–50% solid content could be coated onto glass and polyethylene terephthalate (PET) substrates, and they formed transparent O-I hybrid coating films via a thermal curing process. The formation of O-I hybrid nanoparticles of size 10–15 nm dispersed in cured coating films could be confirmed using scanning electron microscopy. The hardness of the cured coating varied with the type of AFAP used in its preparation, which was monitored using pencil hardness and nanoindentation measurements.
