【Materials & Design】Fabrication of antibacterial electrospun nanofibers with vancomycin-carbon nanotube via ultrasonication assistance
Abstract:
The aggregation of multi-walled carbon nanotubes (MWCNT) into the polymer matrix and weak bactericidal property of MWCNT usually limit the application of MWCNT in the infection resistance. To solve the above problem, vancomycin hydrochloride modified multi-walled carbon nanotube (Van-MWCNT) via the chemical reaction of the MWCNT inherent carboxyl group and the Van amide group was we...

Biodegradable polylactide based materials with improved crystallinity, mechanical properties and rheological behaviour by introducing a long-chain branched copolymer
Herein we developed a novel strategy for preparing biodegradable polylactide (PLA) based materials with improved crystallinity, mechanical properties and rheological behaviour by introducing a long-chain branched block copolymer (LB-PCLA) of PLA and poly-3-caprolactone (PCL). The LB-PCLA copolymer was synthesized by single hydroxyl-terminated PLA (PLA-OH) and three hydroxyl-termin...

Regioselective Chain Shuttling Polymerization of Isoprene: An Approach To Access New Materials from Single Monomer
Chain
shuttling polymerization (CSP) has exhibited unique privilege to combine monomer
sequences of different properties into one macromolecular chain, which,
however, is difficult to achieve because of low chain transfer efficiency and
thus lead to poor architecture control over the resulting polymers. Herein, we
reported that the pyridyl–methylene fluorenyl scandium complex 1 in
com...

[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...
