UV-curable polyurethane-acrylate hybrids made by a prepolymer-free process and free-standing polymer-metal oxide films made in a wholly water-based UV curing process

Abstract

Acrylates are widely used for UV curing to coat substrates and to form shaped articles. Of late, UV curing has gained prominence in 3D printing and additive manufacturing technologies. The process described here helps in enhancing the concentration of acrylates at specified locations of the polymer chain, is free from volatile components, and is entirely based on water.
