[ACS Macro Letter]Tunable and Processable Shape-memory Materials Based on Solvent-Free, Catalyst-free Polycondensation between Formaldehyde and Diamine at Room Temperature
Compared with traditional thermosets, malleable thermosets have more applications in aerospace, biotechnology, and construction. Here we report a one-step, solvent-free, catalyst-free polycondensation method between diamine and formaldehyde to prepare a series of malleable hemiaminal dynamic covalent networks (HDCNs). The materials have excellent malleability and reprocessability by hot pressing...

[Journal of Materials Chemistry C]Superior electromagnetic interference shielding 3D graphene nanoplatelets/reduced graphene oxide foam/epoxy nanocomposites with high thermal conductivity
How to design the microstructure of polymer nanocomposites to significantly improve their electromagnetic interference shielding effectiveness (EMI SE) is still a great challenge. Herein, we developed a template method for fabricating the 3D porous graphene nanoplatelets/reduced graphene oxide foam/epoxy (GNPs/rGO/EP) nanocomposites, in which 3D rGO foam embedded with GNPs constructs a 3D electr...

Super tough biobased poly(ethylene 2,5-furandicarboxylate) materials: synthesis and thermo-mechanical properties of poly(ethylene 2,5-furandicarboxylate-mb-poly(tetramethylene glycol)) multiblock copolymers.
Poly(ethylene 2,5-furandicarboxylate) (PEF) is a biobased polyester with superior thermo-mechanical and gas barrier properties than poly(ethylene terephthalate) (PET), the most widely used petroleum-based polyester. However, PEF is more brittle than PET. To toughen PEF, a series of P(EF-mb-PTMG) (PETF) multiblock copolymers with high intrinsic viscosity were successfully synthesized via melt pol...

【ACS Applied Materials & Interfaces-2012年秋季】Asymmetric Free-Standing Film with Multifunctional Anti-Bacterial and Self-Cleaning Properties
A superhydrophobic/hydrophilic asymmetric free-standing film has been created using layer-by-layer assembly technique. Poly(ethyleneimine)-Ag + complex (PEI-Ag + ) at pH 9.0 was assembled with poly(acrylic acid) (PAA) at pH 3.2 on a Teflon substrate to yield a micronanostructured surface that can be turned to be superhydrophobic after being coated with a low surface energy co...

【69 Applied Materials Today】 "Cooking carbon in a solid salt": Synthesis of porous heteroatom-doped carbon foams for enhanced organic pollutant degradation under visible light
Porous heteroatom-doped carbons are desirable for catalytic reactions due to their tunable physicochemical properties, low cost and metal-free nature. Herein, we introduce a facile, general bottom-up strategy, so-called “cooking carbon in a solid salt”, to prepare hierarchically porous heteroatom-doped carbon foams by using poly(ionic liquid) as precursor and a common inorganic salt as structura...

【64 Applied Materials Today】 Main-chain poly(ionic liquid)-derived nitrogen-doped micro/mesoporous carbons for CO2 capture and selective aerobic oxidation of alcohols
Sustainable development and the recent fast-growing global demands for energy and functional chemicals urgently call for effective methods for CO2 remediation and efficient metal-free catalysts for selective oxidation of aromatic alcohol. Herein, a unique main-chain poly(ionic liquid) (PIL) is employed as the precursor to prepare nitrogen-doped micro/mesoporous carbons via simultaneous carbonizati...

【38 Journal of Materials Chemistry A】 One-pot synthesis of core/shell Co@C spheres by catalytic carbonization of mixed plastics and their application in the photo-degradation of Congo red
Much attention has been paid to the synthesis of core/shell metal@carbon composites, but many of the proposed methods are limited by sophisticated procedure and expensive precursors. Herein, a facile one-pot approach is established to prepare magnetic core/shell Co@C spheres through catalytic carbonization of mixed plastics (consisting of polypropylene, polyethylene and polystyrene) by Co3O4 at 70...

[Macromolecular Materials & Engineering] Highly Flexible, Tough, and Self-Healable Hydrogels Enabled by Dual Cross-Linking of Triblock Copolymer Micelles and Ionic Interactions
Development of artifcial soft materials that have good mechanical performances and autonomous healing ability is a longstanding pursuit but remains challenging. This work reports a kind of highly ?exible, tough, and self-healable poly(acrylic acid)/Fe(III) (PAA/Fe(III)) hydrogels. The hydrogels are dually cross-linked by triblock copolymer micelles and ionic interaction between Fe(III) and carbo...

[ACS Applied Materials & Interface] Dually Synergetic Network Hydrogels with Integrated Mechanical Stretchability,Thermal Responsiveness and Electrical Conductivity for Strain Sensors and Temperature Alertors
The first example of dually synergetic network hydrogel, which has integrated mechanical stretchability, thermal responsiveness, and electrical conductivity, has been constructed by a versatile and topological co-cross-linking approach. Poly(N-isopropylacrylamide) (PNIPAAm) is introduced as the thermally responsive ingredient, and polyaniline (PANI) is selected as the electrically conductive ing...
