[ACS Appl. Mater. Interfaces] Fe3+-, pH-, thermo-responsive supramolecular hydrogel with multi-shape memory effect
Poor, non-tunable mechanical properties as well as finite shape memory performance pose a barrier to shape memory hydrogels to realize practical applications. Here, a new shape memory hydrogel with tunable mechanical properties and multi-shape memory effect was presented. Three programmable reversible systems including PBA-diol ester bonds, AAc-Fe3+ and coil-helix
transition of agar were applied t...

Amino-functionalized Poly (N-vinylcaprolactam) Derived from Lysine: Sustainable Polymer with Thermo and pH Dual Stimuli Response.
Lysine, a renewable feedstock with economic feasibility, was tactfully cyclized to its corresponding cyclic lysine and then subjected to a reaction with acetylenes to yield a sustainable N-vinylcaprolactam (VCL) derivative. Subsequent MADIX/RAFT copolymerization of the resultant monomer gave well-defined PVCL bearing pendant 2,5-dimethylpyrrole protected amino groups with narrow polydispersity.

[RSC Adv.] Dextran-based thermo-responsive hemoglobin–polymer conjugates with oxygen-carrying capacity
The potential toxicity towards human kidneys of hemoglobin (Hb), when used directly, has severely limited its application as a red blood cell substitute and in cancer treatments. In this work, a novel hemoglobin–polymer conjugate was prepared by a reaction between the lysine amino groups of Hb and the carboxyl groups of a copolymer, poly(N-isopropylacrylamide) grafted carboxylated dextran (HOOC...

[Materials] Encapsulation of Hydrophobic Phthalocyanine with Poly(N-isopropylacrylamide)/Lipid Composite Microspheres for Thermo-Responsive Release and Photodynamic Therapy
Phthalocyanine (Pc) is a type of promising sensitizer molecules for photodynamic therapy (PDT), but its hydrophobicity substantially prevents its applications. In this study, we efficiently encapsulate Pc into poly(N-isopropylacrylamide) (pNIPAM) microgel particles, without or with lipid decoration (i.e., Pc@pNIPAM or Pc@pNIPAM/lipid), to improve its water solubility and prevent aggregation in a...

Synthesis, thermo-mechanical and rheological properties of biodegradable long-chain branched PBST copolyesters
Biodegradable long-chain branched (LCB) poly(butylene succinate-co-butylene terephthalate) (PBST) copolyesters were prepared via a two-step direct esterification and melt polycondensation process, using a small amount (0-2 mol %) of diglycidyl 1,2,3,6-tetrahydrophthalate (DGT) as an in situ branching agent (BA). The chemical structures of LCB PBSTs were characterized and the thermal, m...

Thermo-responsive photoluminescent polymer brushes device as a platform for selective detection of Cr(VI)
In this work, we first report a thermo-responsive photoluminescent polymer brushes device as a platform
for the selective and sensitive detection of Cr(VI). Positively charged fluorescent molecules of a quaternary
ammonium tetraphenylethylene derivative (d-TPE) are immobilized in the thermo-responsive polymer
brushes of p(NIPAM-co-AAc) by Coulombic force, which leads to the observation of an immob...

A Borinic Acid Polymer with Fluoride Ion- and Thermo-responsive Properties that are Tunable over a Wide Temperature Range
A new type of smart borinic acid polymer with luminescence and multiple stimuli-responsive properties is reported. In DMSO with small amounts of water, the homopolymer PBA shows a tunable upper critical solution temperature (UCST). As the amount of water increases from 0 to 2.5% (v/v), the UCST rises linearly from 20 degrees C to 100 degrees C (boiling point of water). Thus, the thermal responsive...

Improvement of the thermal and thermo-oxidative stability of high-density polyethylene by free radical trapping of rare earth compound
A kind of rare earth compound, ytterbium trifluoromethanesulfonate (Yb(OTf)3), was introduced into high-density polyethylene (HDPE) by melt compounding to investigate the effect of Yb(OTf)3 on the thermal and thermo-oxidative stability of HDPE. The results of thermogravimetric (TG) and differential scanning calorimetry (DSC) showed that the addition of Yb(OTf)3 made the thermal degradation tempera...
