摘要：
The colloidal behavior of poly(N-isopropylacrylamide) and poly(ethylene oxide) (PNIPAM-b-PEO) block copolymers and their corresponding microgels in aqueous solutions were studied. The microgels were synthesized using a redox system consisting of ceric ion (Ce) and PEO. The nanoparticles formation of the microgels were controlled by changing the heating rates. Smaller particle dimension with a narrower size microgels were obtained by the fast heating process.
