Thermo-responsive rheological behavior of borinic acid polymer in dilute solution.
In comparison with other boron containing polymers, the investigations on the borinic acid containing polymers have been mostly ignored in spite of their easy synthesis. Our previous studies indicate a borinic acid polymer (PBA) holds promising potential as a new type of stimuli-responsive polymer. However, the property investigations were mainly based on turbidity changes. Here, we report the r...

Thermo-responsive behavior of borinic acid polymers: experimental and molecular dynamics studies
The thermo-responsive properties of borinic acid polymers were investigated by experimental and molecular dynamics simulation studies. The homopolymer poly(styrylphenyl(tri-iso-propylphenyl)borinic acid (PBA) exhibits an
upper critical solution temperature (UCST) in polar organic solvents that is tunable over a wide temperature range by addition of small amounts of H2O. The UCST of a 1 mg/mL PBA...

Thermo-sensitive photoluminescent hydrogels: synthesis, characterization, and their drug-release property
Multifunctional hydrogels that simultaneously possess semi-interpenetrating networks structure, strong photoluminescence, and temperature sensitivity were successfully fabricated based on the crosslink of poly (acrylamide) (PAAm) in the presence of poly(N-isopropylacrylamide) (PNIPAM) and CdTe quantum dots (QDs) at a mild condition. With the increase of external temperature, the photoluminescence ...

Terminal modification with 1-adamantylamine to endow hyperbranched polyamidoamine with thermo-/pH-responsive properties
A
novel terminal modification agent to endow hyperbranched polyamidoamine
(HPAMAM) with thermo-/pH-responsive properties is reported. HPAMAM with
terminal vinyl groups is first synthesized and then end-capped by
1-adamantylamine (ADA). The resulting hyperbranched polymer (HPAMAM-ADA)
shows interesting thermo-responsive properties in aqueous solution,
which have been investigated by UV-...

Super-tough and thermo-healable hydrogel – promising for shape-memory absorbent fiber
Recoverable hydrogels with high stretch and toughness have been synthesized by one-step radical polymerization. They consist of covalently crosslinked polyacrylamide (PAAm) and ionically crosslinked carrageenan. Such double network (DN) hydrogels can be stretched beyond 20 times its initial length, and their fracture energy reached a high value of ~9500 J/m2. By comparing hydrogel tensile properti...

Thermo-responsive Modification and Properties Study of PVDF Flat Membrane
A thermo-responsive membrane, PVDF-g-PNIPAAm, was successfully prepared from poly(vinylidene fluoride) (PVDF) membrane through surface-initiated atom transfer radical polymerization (ATRP) of a thermo-responsive monomer, N-isopropyl acrylamide (NIPAAm). The effect of the mass ratio of PVDF membrane to NIPAAm monomer on ATRP was studied in detail. The grafting copolymer was characterized by scannin...

Thermal and thermo-oxidative degradation of High density polyethylene/Fullerene nanocomposites
Fullerene (C60)/high density polyethylene (HDPE) nanocomposites were studied in order to understand for their behaviors on thermal and thermo-oxidative degradation. Under different atmosphere, the influences of C60 on the thermal stability of HDPE are different. Thermogravimetric analysis coupled to Fourier transform infrared spectroscopy (TG-FTIR) and pyrolysis-gas chromatography-mass spectrometr...

17. Characterization of pH- and thermo-sensitive hydrogel as a vehicle for controlled protein delivery
N-[(2-Hydroxy-3-trimethylammonium)propyl] chitosan chloride (HTCC) was chemically modified using glycidyltrimethylammonium chloride (GTMAC). A new composite hydrogel was prepared using the mixture of HTCC and α-β-glycerophosphate (α-β-GP). The gelation of HTCC/GP mainly depended on the concentration and proportion of HTCC and GP. Thermogravimetric analysis exhibited high stab...

A New Family of Thermo-responsive Polymers Based on Poly[N-(4-vinylbenzyl)-N,N-dialkylamine]
A new family of the thermo-responsive polymers based on poly[N-(4-vinylbenzyl)-N,N-dialkylamine] with the pendent amine group as well as the doubly thermo-responsive triblock copolymer were synthesized by reversible addition–fragmentation chain transfer (RAFT) polymerization. These polymers showed the lower critical solution temperature (LCST) and/or the upper critical solution temperature (...
