Novel waterborne fluorinated polyurethane (WFPU) based on hydroxyl-terminated poly(fluoroalkyl methacrylates) (HTPFMA) was prepared successfully. The microstructures and micro-phase separation of WFPU were evaluated through infrared spectroscopy (FT-IR), X-ray diffraction (XRD), dynamic mechanical analysis (DMA), and scanning electron microscope (SEM). FT-IR revealed that the H-bonded carbonyl in...
A novel zwitterionic pendant copolymer poly(2-(methacryloyloxy)ethyl phosphorylcholine)-co-poly(2-(methacryloyloxy)ethyl adamantane-1-carboxylate) (poly(MPC-co-Ada)) is synthesized via reversible addition-fragmentation chain transfer (RAFT) polymerization. The pendant adamantane guest molecules and doxorubicin (DOX) decorated β-cyclodextrins (DOX-hyd-CD) can form inclusion complexation through host-guest...
Biomimic hyaluronic acid (HA) prodrug micelles with pH and reduction responsiveness were prepared by chemical graft of phosphorylcholine and doxorubicin (DOX) to the backbone of HA. DOX was conjugated to HA by pH-sensitive hydrazone bonds which could be hydrolyzed under acidic conditions and thus resulted in controlled release of DOX. Besides, the HA prodrug micelles were cross-linked via reduction-responsive...
A novel amphiphilic photo-degradable hyperbranched polymer was reported at the first time. The hyperbranched o-nitrobenzyl containing poly(amino ester)s (HPAE) were prepared by one-pot Michael addition polymerization. The photo-induced degradation of hyperbranched poly(amino ester)s was confirmed by gel permeation chromatography (GPC) and UV-vis spectra. Bioinspired phosphorylcholine grafted HPAE...
