【[Chemical Society Reviews]】Supramolecular shape memory hydrogels: a new bridge between stimuli-responsive polymers and supramolecular chemistry
Supramolecular shape memory hydrogels (SSMHs) refer to shape memory polymers, in which temporary shapes are stabilized by reversible crosslinks such as supramolecular interactions and dynamic covalent bonds. Following a brief introduction of the conventional shape memory polymers (SMPs), this tutorial review is focused to summarize the recent advancement in various reversible crosslinks employed t...

PMS-Towards Sustainable Ultrafast Molecular-Separation Membranes: from Conventional Polymers to Emerging Materials
Ultrafast molecular separation (UMS) membranes are highly selective towards active organic molecules such as antibiotics, amino acids and proteins that are 0.5-5 nm wide while lacking a phase transition and requiring a low energy input to achieve high speed separation. These ad...

Synthesis and CO2 Capture Behavior of Porous Crosslinked Polymers Containing Pendant Triazole Groups.
Porous cross-linked polymers containing pendant triazole groups were synthesized from glycidyl methacrylate (GMA) in the presence of divinylbenzene via high internal phase emulsion (HIPE) templating method followed by functionalization with sodium 3-amino-1,2,4-triazole (ATANa). They were characterized with FTIR, SEM, BET, and mercury intrusion and assessed as C...

[Polymers] Unusual Emission of Polystyrene-Based Alternating Copolymers Incorporating Aminobutyl Maleimide Fluorophore-Containing Polyhedral Oligomeric Silsesquioxane Nanoparticles
In this study, we synthesized an unusual 2-aminobutyl maleimide isobutyl polyhedral oligomeric silsesquioxane (MIPOSS-NHBu) monomer lacking conventional fluorescent groups. We then prepared poly(styrene-alt-2-aminobutyl maleimide isobutyl POSS) [poly(S-alt-MIPOSS-NHBu)] and poly(4-acetoxystyrene-alt-2-aminobutyl maleimide isobutyl POSS) [poly(AS-alt-MIPOSS-NHBu)] copolymers through facile free r...

Synthesis and AIE properties of PEG-PLA-PMPC based triblock amphiphilic biodegradable polymers
Using a O,N,N,O-tetradentate Salan yttrium alkyl complex as the precursor and monohydric PEG as the chain transfer agent, rac-LA and MPC monomers were sequentially ring-opening polymerized via living immortal mode to give biodegradable triblock amphiphilic copolymers of (PEG-b-PLA-b-PMPC) (PEG = poly(ethylene glycol) and MPC = 5-methyl-5-propargyloxycarbonyl-propylene carb...

Effect of Polymers and Media Type on Extending the Dissolution of Amorphous Pioglitazone and Inhibiting the Recrystallization from a Supersaturated State
Amorphous forms of crystalline drug are widely utilized for bioavailability enhancement of low solubility drugs in the pharmaceutical industry. Polymers have been found to be effective crystallization inhibitors for amorphous forms in solid states during storage or in liquid states during dissolution process. The dissolution and crystallization behaviors of these amorphous forms in the presence or...

Impact of amorphous and semicrystalline polymers on the dissolution and crystallization inhibition of pioglitazone hydrochloride solid dispersions
Solid dispersions are used as a useful approach to improve the dissolution rate and bioavailability of poorly water-soluble active pharmaceutical ingredients (APIs). The present study investigated the impact of amorphous polymers (polyvinylpolypyrrolidone K30 and polyvinylpolypyrrolidone K90) and semicrystalline polymers (polyethyleneglycol 6000 and polyethylene–polypropylene glycol 188) on the...

(ACS Applied Materials & Interfaces) Local Controllable Laser Patterning of Polymers Induced by Graphene Material
Graphene has been successfully applied to the field of polymer laser patterning. As an efficient 1064 nm near-infrared (NIR) pulsed laser absorber, the graphene prepared by the mechanical exfoliation of only 0.005 wt% (50 ppm) endowed polymer materials with a very good performance of NIR pulsed laser patterning. Optical microscopy observed that the generated black patterns came from the local di...

[Polym.Chem.]ABx -type amphiphilic macromonomer-based supramolecular hyperbranched polymers for controllable self-assembly
A macromonomer strategy has displayed potential advantages of constructing functional supramolecular hyperbranched polymers (SHPs); however, owing to the limited functional group number and weak noncovalent interactions, it is difficult to control the dynamic self-assembly process of SHPs based on the reported AB 2 -type hydrophilic macromonomers. In this work, a novel SHP was fir...
