[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...

42. [Materials Chemistry and Physics] The tough allograft adhesive behavior between polyacrylamide and poly(acrylic acid) hydrophobic association hydrogels
Polyacrylamide (PAAm) and polyacrylic acid (PAAc) hydrophobic association hydrogels were synthetized via free radical polymerization, respectively. Also, the hydrophobic alkyl groups were introduced into PAAm and PAAc to enhance the mechanical properties of hydrogels. It was found that PAAm and PAAc hydrophobic association hydrogels didn''''''''''''''''''''''''''''''''''''''''''''''''''''...

【Applied Materials Today】Continuous fabrication of polymer microfiber bundles with interconnectedmicrochannels for oil/water separation
Recently, the development of methods for the cleanup of large-scale oil spills or organic pollutants fromwater has been attracting global attention. However, traditional techniques suffer from the limits of lowefficiency and high operation cost. Herein, we propose a high efficiency, large-scale and easy operationapproach to fabricate a hydrophobic and oleophilic high density polyethylene microfibe...

Materials Letters-A novel“gel–sol” strategy to synthesize TiO2nanorod combining reduced graphene oxide composites
In this study, a novel so-called “gel–sol” process isfirstly reported for synthesis of TiO2nanorod (TN)
combining reduced graphene oxide (RGO) composites. By utilizing the triethanolamine (TEOA) as shape
controller and under specific conditions (such as pH?12), the hybrid composites can be readily obtained.
The higher pH value benefits the deprotonation of TEOA for adsorption to the ...

【Journal of Materials Chemistry A】Morphology-Dependent Electrochemical Supercapacitors in Multi-Dimensional Polyaniline Nanostructures
While some polyaniline (PANI) morphologies have been reported, its synthesis with regular structure in multi-dimensions has met with limited success. Here, well-defined PANI spheres, roses, cloud-like and rhombic plates, layered flowers, columns, blocks, and dendrites were prepared by employing static surfactant systems in a 0.010 M HCl solution at room temperature. The acquisition of these ...

【Journal of Materials Chemistry C】Hyperbranched polysiloxane (HBPSi)-based polyimide films with ultralow dielectric permittivity, desirable mechanical and thermal properties
Low-dielectric polyimide (PI) is on high demand in the next generation of high-density and high-speed integrated circuits. The introduction of fluorine or pores into PIs has been reported to efficiently obtain low-dielectric properties, but unavoidably deteriorate the mechanical and/or thermal properties. Therefore, it is a great challenge for PI to decrease its Dkand simultaneously maintain...

Fully biodegradable food packaging materials based on functionalized cellulose nanocrystals/ poly(3-hydroxybutyrate-co-3-hydroxyvalerate) nanocomposites
Current packaging materials (mainly composed of petroleum-based synthetic polymers) face environmental and disposal issues, and as a result, developing eco-friendly and bio-based nanocomposites as alternatives have motivated academic and industrial research. We report here on our effort to develop a transparent nanocomposite-based packaging film comprised of poly(3-hydroxybutyrate-co-3-hydroxyvale...

Enhanced heat conduction in cellulose nanocrystals grafting polyeth- ylene glycol as solid-solid phase change materials
Green copolymers as phase change material were prepared by grafting polyethylene glycol (PEG) onto a rigid molecular skeleton of cellulose nanocrystals (CNs), and their thermal properties were studied by thermal delay method and differential scanning calorimetry. The influences of the CNs on the thermal conductivity behavior and thermal energy storage capacity of the copolymers&nb...

32. High-performance conductive materials based on the selective location of carbon black in poly(ether ether ketone)/polyimide matrix
A novel high performance conductive material with excellent comprehensive properties was prepared by melt-blending, and its performances were adjusted by controlling the selective location of carbon black (CB) in poly(ether ether ketone) (PEEK)/thermoplastic polyimide (TPI) matrix. With increasing the CB loadings, the morphology of PEEK/TPI blends changed from sea-island to co-continuous structure...
