Abstract:
The large-scale preparation of block copolymer nano-objects with tunable and reversible carbon dioxide (CO2) responsiveness is a challenging goal in the polymer community. Herein, an open-air strategy via enzyme-assisted photoinitiated polymerization-induced self-assembly (photo-PISA) in water is developed for preparing cross-linked CO2-responsive vesicles at high solids contents. The CO2 responsiveness of these vesicles can be controlled by changing the composition of the core-forming block. Finally, inorganic/organic hybrid vesicles are prepared by mixing CO2-responsive vesicles with silica (SiO2) nanoparticles, and the amount of SiO2 nanoparticles can be further increased by treating with CO2.

Photochemical Initiation Of Radical Polymerization Reactions
In this video, we will carry out the photochemically initiated polymerization of styrene to generate polystyrene, which is an important commodity plastic. We will learn the fundamentals of photochemistry and use simple photochemistry to initiate radical polymerization reactions. Specifically, in this module we will examine the photochemistry of benzoyl peroxide and its role as a photo-initiator of styrene polymerization reactions. In the...
