Synthesis of polyethylene glycol diacrylate nanogel using irradiation of inverse micelles technique

The purpose of the work described here was to prepare covalently crosslinked nanogel from polyethylene glycol diacrylate (PEGDA) using an inverse micelle system as a template for irradiation via electron beam. Inverse micelles were formed by addition of sodium dioctyl sulfosuccinate (AOT) in n-heptane above its critical micelle concentration. These nano sized micelles were used to trap PEGDA in its water phase. Irradiation of the PEGDA containing micelles leads to formation of many radicals and recombinations thus forming crosslinked nanogel.
