Abstract
In this work, thermo-responsive macroporous Poly (acrylamide-co-N-isopropylacrylamide) (PAM-co-PNIPAM) microspheres with certain lower critical solution temperature (LCST) were synthesized by inverse suspension polymerization approach in the presence of toluene as porogenic agents. Various types of measurements, such as scanning electron microscopy (SEM), Fourier transform infrared (FT-IR), Laser Particle Size Distribution Analyzer, N2 absorption analysis (BET) and Mercury Intrusion Porosimetry were conducted in characterizing PAM-co-PNIPAM particles. The results indicated that the obtained PAM-co-PNIPAM microspheres are perfect with porous structures which make the copolymer possess large surface area. And the size of the PAM-co-PNIPAM microspheres would change with the environmental temperature which is called thermo-responsive. Moreover, the copolymer synthesized from higher monomer weight ratio of AM/NIPAM has a relatively higher LCST.
