[Chem. Commun.] Actuating and Memorizing Bilayer Hydrogel for a Self-deformed Shape Memory Function
A general strategy for fabricating a double layer self-deformed
shape memory hydrogel which includes a thermo-responsive actuating layer and a
pH-responsive memorizing layer is presented. Compared with traditional shape
memory polymer systems, the temporary shape of the hydrogel could be generated by
thermo-responsive actuating layer upon the trigger of heat without the need of external
force, whi...

[J.Phys.Chem.C ]Highly Efficient Electromagnetic Wave Absorbing Metal-Free and Carbon-Rich Ceramics Derived from Hyperbranched Polycarbosilazanes
Abstract: The highly efficient electromagnetic (EM) wave absorbing metal-free and carbon-rich ceramics derived from hyperbranched polycarbosilazanes were presented in this contribution. The novel metal-free hyperbranched polycarbosilazanes with pendant cyano groups (hb-PCSZ-cyano) were synthesized through aminolysis reaction and subsequent Michael addition reaction, i.e. cyanoethylation reaction...

8.【J. Phys. Chem. B】Network Structure Control of Binary Mixed Langmuir Monolayers of Homo-PS and PS-b-P2VP.
Our recent work showed there existed a composition window for mixed Langmuir monolayers of homopolystyrene (h-PS) and a symmetric diblock copolymer polystyrene-block-poly(2-vinylpyridine) (PS-b-P2VP) to form necklace-network structures at the air/water interface. In order to study further the possible mechanism and control the network structure (i.e., surface coverage and nanoaggregate diameter)...

(J. Am. Chem. Soc.) Near Infrared Chromophore Functionalized Soft Actuator with Ultrafast Photoresponsive Speed and Superior Mechanical Property
In this Communication, we develop a twostep acyclic diene metathesis in situ polymerization/crosslinking method to synthesize uniaxially aligned main-chain liquid crystal elastomers with chemically bonded nearinfrared absorbing four-alkenyl-tailed croconaine-core cross-linkers. Because of the extraordinary photothermal conversion property, such a soft actuator material can raise its local temper...

(J. Mater. Chem. C) Hydrogen-Bonding Induced Melamine-Core Supramolecular Discotic Liquid Crystals
Recognition of melamine is not only of food industry importance but also an interesting scientific research topic. The objective of this work is to screen suitable hydrogen-bonding complementary compounds for the construction of melamine-core supramolecular discotic liquid crystal (LC) materials which might provide a LC perspective for detection and separation of melamine in the future. We desig...

2017-Polym Chem: Energy Dissipation and Mullins Effect of Tough Polymer/Graphene Oxide Hybrid Nanocomposite Hydrogels
Nanocomposite
hydrogels (NC gels) are considered as one of high strength hydrogels. Graphene
oxide (GO), thanks to its amphiphilic, mechanical, optical property, is widely
used as fillers to incorporate into different hosting materials (elastomers, plastics,
and hydrogels) to improve their mechanical properties. In this work, we used in
situ free radical polymerization to synt...

【J. Phys. Chem. C】Tunable Permittivity in High–Performance Hyperbranched Polyimide Films by Adjusting Backbone Rigidity
Currently, low-dielectric polyimides (PIs) such as fluorinated or porous PIs exhibit a low-dielectric property but have undesirable mechanical and/or thermal properties. Therefore, it is crucial to find a more considerate method that could lower the permittivity, while maintaining or improving the mechanical and thermal properties. Herein, a series of hyperbranched (HB) PI films were synthes...

[J Mater Chem A]Indacenodithiophene: A Promising Building Block for High Performance Polymer Solar Cells
Harvesting energy directly from sunlight using photovoltaic technology has become an essential component of future global energy production. Although silicon-based inorganic materials have still played a dominant role in the market, problems for inorganic materials-based solar cells mainly lie in (1) high cost of production and technical difficulties in the fabrication of large-ar...

(ACS Sustain. Chem. Eng.) Hexahydro-s-triazine: A Trial for Acid-Degradable Epoxy Resins with High Performance
Hexahydro-s-triazine (HT) derivatives are acidsensitive compounds. 4,4′,4″-(1,3,5-Hexahydro-s-triazine-1,3,5-triyl) tris(N-(2-aminoethyl) benzamide) (HT-A) bearing three amino groups was synthesized as a curing agent to prepare the acid-degradable epoxy resin. The chemical structures of HT-A and its precursor were confirmed by 1H NMR and 13C NMR. The synthesized HT-A, as well as the commer...
