doi:10.7517/j.issn.1674-0475.2017.05.007

Abstract

Abstract:

In this paper,poly(glycerol monomethacrylate) (PGMA) was used as the macromolecular chain transfer agent, 2-hydroxypropyl methacrylate (HPMA) and 2-(dimethylamino)ethyl methacrylate (DMAEMA) were used as monomers to prepare CO₂-responsive vesicles via aqueous photoinitiated polymerization-induced self-assembly at room temperature. Kinetic study confirmed that full monomer conversion was achieved after 10 min of visible light irradiation (405 nm, 0.5 mW/cm²). Moreover, the effect of DMAEMA on the polymerization was also studied in detail. Finally, the CO₂-responsive property of the obtained vesicles was studied by visual appearance, transmission electron microscope (TEM) and nuclear magnetic resonance (NMR).

Key words: CO₂-responsive, PISA, photoinitiated, polymer vesicle
