[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)...

[Angew. Chem. Int. Ed.] Tuning Crystallization Pathways through Mesoscale Assembly of Biomacromolecular Nanocrystals
Macromolecular crystallization has many implications in biological and materials science. Similar to the crystallization of other molecules, macromolecular crystallization conventionally considers a critical nucleus, followed by crystallographic packing of macromolecules to drive further crystal growth. Here, we discover a distinctive macromolecular crystallization pathway by developing a concep...

(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...

[Angew. Chem. Int. Ed.] Environmentally Benign, Rapid and Selective Extraction of Gold from Ores and Waste Electronic Materials
The extraction of gold from ores and electronic waste is an important topic worldwide, as this precious metal has immense value in a variety of fields. However, serious environmental pollution and high energy consumption due to the use of toxic oxidation reagents and harsh reaction conditions is a well-known problem in the gold industry. Herein, we report a new chemical method based on th...

【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...
