The chemically inert surface and strong ionic bonds make exfoliation functionalization of hexagonal boron nitride (h-BN) difficult. This inevitably increases the interface thermal resistance hinders phonon transfer. Herein, polydopamine (PDA)-coated exfoliated h-BN, denoted as h-BN@PDA, was prepared by a one-step ball milling route. During process, dopamine self-polymerized into PDA on h-BN@PDA in an alkaline aqueous solution. coated contents were estimated to be about 3 wt %. Meanwhile,...
Orientational hBN/SEBS composite films embued with superior thermal conductivity and improved dimensional stability were prepared by hot-pressing treatment.
Asymmetric catalysis is the preferred method for synthesis of pure chiral molecules in fine chemical industry. Cellulose has long been sought as a support enantioselective catalysis. Dialdehyde cellulose (DAC) produced by selective oxidation and used to bind 5,5′-diamino Binap forming Schiff base. Here, we report modified cellulose-supported Rh novel biomass-supported catalyst characterization its morphology, composition, thermal stability. DAC-BINAP-Rh was very effective asymmetric...
A simple, easy-to-operate, and green route was developed to fabricate graphene-AgNPs/lignocellulose electrothermal film. Impressively, an outstanding steady-state temperature of 214 °C under 7 V attained with 20 wt% graphene-AgNPs.
Abstract The ring‐opening polymerization of L ‐lactide initiated by single‐component rare‐earth tris(4‐ tert ‐butylphenolate)s was conducted. influences the elements, solvents, temperature, monomer and initiator concentrations, reaction time on were investigated in detail. No racemization found from 70 to 100 °C under examined conditions. NMR differential scanning calorimetry measurements further confirmed that occurred without epimerization or polymer. A kinetic study indicated rate...
Abstract Ring‐opening polymerization of D,L ‐lactide (LA) has been successfully carried out by using rare earth 2,6‐dimethylaryloxide (Ln(ODMP) 3 ) as single component catalyst or initiator for the first time. The effects different elements, solvents, monomers and concentration well temperature time on were investigated. results show that La(ODMP) exhibits higher activity to prepare poly( ‐lactide) (PLA) with a viscosity molecular weight 4.5 × 10 4 g mol −1 conversion 97 % at 100 °C in 45...
Abstract Block copolymers of ϵ‐caprolactone (CL) and L‐lactide (LLA) can be prepared by ring‐opening polymerization in toluene using a single component lanthanum tris(2,6‐dimethylphenolate)s [La(ODMP)3] as catalyst. The mutual reactivity these two comonomers indicates the order their addition is critical, that CL must first polymerized followed LLA polymerization. 1H 13C NMR spectra polymer clearly show diblock copolymer structure without random placement. Analysis thermal property...
Abstract Highly random copolymers of 2,2 ‐dimethyltrimethylene carbonate (DTC) and ε‐caprolactone (CL) were synthesized by single component rare‐earth tris(4‐ tert ‐butylphenolate)s [Ln(OTBP) 3 ] for the first time. The influences reaction conditions on copolymerization initiated La(OTBP) have been examined in detail. monomer reactivity ratios DTC CL determined Fineman–Ross method are 4.0 r 0.27 . microstructure copolymer was analyses diads DTC–DTC, DTC–CL, CL–DTC CL–CL 1 H NMR spectra. high...
The low thermal expansion coefficient, dielectric constant, high conductivity, electrical resistivity, and excellent stability of hexagonal boron nitride (hBN) make it an ideal filler for insulating thermally conductive composite films. Its use has been suggested in packaging systems to solve the heat dissipation problems modern electronic equipment. Here, a novel strategy was proposed construct superior networks via vacuum-assisted filtration hydroxyl-modified (BN-OH) lignocellulosic fiber...
