WebPDA is typically obtained from topopolymerization of appropriate diacetylene monomers. Diacetylene lipids have recently emerged as one of the most studied class of monomers because they can form nano-structured vesicles uniformly dispersed in an aqueous medium. The vesicle solution can in turn be polymerized efficiently by UV-irradiation. WebPhotopolymerization is the polymerization of liquid by being exposed to light, typically ultraviolet (UV) light. Polymerization is the process of liquid turning to solid by building …
