英文摘要 | Poly(n-isopropylacrylamide) (pnipam) has attracted intensive interest for bio-medical applications due to its unique thermal properties whereby it displays a lower critical solution temperature (lcst) close to body temperature. it is well known that the lcst of pnipam can be tuned by incorporating a second component. in this study, a library of (co)polymers of nipam and n-(2-hydroxypropyl) methacrylamide (hpma) with varying molecular weight (mw), composition, and end functionality were synthesized by reversible addition-fragmentation chain transfer (raft) polymerization to systematically investigate how these factors influence their thermo-responsive behavior. our findings include: (1) the lcst of nipam-co-hpma (co) polymers increases with hpma content (fhpma) in the temperature range from 29 to 92 degrees c; (2) the lcst of the polymers is significantly higher when the hydrophobic dithiobenzoate end-group is converted to a thiol-group, however, this influence becomes less pronounced for high mw polymers; (3) the mw of the copolymers has a negligible influence on the lcst. this systematic study investigating the effects of such influencing factors as mw, end group, and polymer composition on the lcst of nipam-containing polymers provides new insights into this class of thermo-responsive polymers. |
