Interpenetrating polymer network (IPN) nanogels based on gelatin and poly(acrylic acid) by inverse miniemulsion technique: Synthesis and characterization

▶ Interpenetrating networks (IPN) were prepared by inverse miniemulsion-IME process. ▶ Physical interaction of gelatin and acrylic acid enables the growth of IPNs. ▶ SEM, TEM, XPS, FTIR and zetapotential studies confirmed IPN structure.
