Nanocomposite hydrogel with varying number of repeating oxyethylene units: Adjustable pore structure and thermo-responsibility
To explore the effect of varying number (n) of repeating oxyethylene units upon the structure, pore shape and property of nanocomposite hydrogels, three kinds of lyotropic liquid crystal molecules polyoxyethylene (n) alkyl ether (Brij-52/56/58) with same alkyl chain C16H33 and different number of oxyethylene units (CH2CH2O)n = 2,10,20) were severed as novel type of template to pre...

A new family of thermo-, pH-, and CO2-responsive homopolymers of poly[oligo(ethylene glycol) (N-dialkylamino) methacrylate]s
A new family of thermo-, pH-, and CO2-responsive homopolymers of poly[oligo(ethylene glycol) (N-dialkylamino) methacrylate]s combining the pendants of oligo ethylene glycol (OEG) moiety and dialkylamine are synthesized by RAFT polymerization.

[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...
