Enhanced thermal conductivity of polyamide 6/polypropylene (PA6/PP) immiscible blends with high loadings of graphite
Abstract: In this study, flake graphite was dispersed in immiscible polyamide 6/polypropylene (PA6/PP) blends to improve their hermal conductivity. Blends of PA6/PP were prepared in different relative fractions and thermal conductivity of the graphite-containing blends showed enhanced values for immiscible blends when compared with those of mono-PA6-based composites at the same graphite lo...

Silicone modified epoxy resins with good toughness, damping properties and high thermal residual weight
Abstract In this research, a series of epoxy-silicone copolymerswere prepared from methyl phenyl silicone intermediates (PMPS) with a bisphenol A type epoxy resin (E-51) by condensation with dilaurate dibutyltin acting as catalyst. The chemical structure of the siloxane-bridged epoxy resin was characterized by Fourier transform infrared spectroscopy (FTIR), 1H-NMR and an epoxy equivalent weight ...

High efficiency grafting of halloysite nanotubes by using π-conjugated polyfluorenes via “click” chemistry
New hybrid halloysite nanotubes (HNTs) were obtained by grafting conjugated
polyfluorenes (PFs) onto the surface via “click” chemistry. The hybrid material can be dispersed in organic solvent such as dichloromethane, and exhibits intense blue emission peaked at 448 nm. The absorption and emission spectra of the HNTs show distinct bathochromic shifts compared to PFs, which can be attributed ...

(JMCA) Readily Recyclable, High-performance Thermosetting Materials based on a Lignin-derived Spiro Diacetal Trigger
Conventional thermosets, widely used in composites, coatings, electronic packing materials, etc., are typically made of non-sustainable fossil resources and cannot be recycled in mild conditions. Degradable thermosets are promising alternatives, while combining readily degradability and high performance is a challenge. In this paper, for the first time, spiro diacetal structure was utilized to b...

High-performance poly (ethylene oxide)/molybdenum disulfide nanocomposite films: reinforcement of properties based on the gradient interface effect
Herein, the molybdenum disulfide (MoS2) was simultaneously exfoliated and non-covalently functionalized by ultrasonication in a Plutonic aqueous solution and then was used, to prepare the poly(ethylene oxide) (PEO) based nanocomposite films. The homogeneous dispersion of MoS2 and strong nanosheets/matrix interfacial adhesion were confirmed by representative electron microscopes. The considerable '...

Metal-coordination crosslinked N-polyindoles as recyclable high-performance thermosets and nondestructive detection for their tensile strength and glass transition temperature
Metal coordination crosslinking between stiff N-polyindole chains was constructed, and the crosslinked films exhibited high tensile strength, high heat resistance and excellent polar solvent resistance. The noncovalent crosslinking can be further removed via external pyrophosphate, which endows the crosslinked polymer with a recyclable behavior. The tensile strength and glass transition temperat...

Recyclable Cu(II)-Coordination Crosslinked Poly(benzimidazolyl pyridine)s as High-Performance Polymers
Crosslinked high-performance polymers have many industrial applications, but are diffcult to recycle or rework. A novel class of recyclable crosslinking Cu(II)-metallo-supramolecular coordination polymers are successfully prepared, which possess outstanding thermal stability and mechanical property. More importantly, the Cu2+ coordination interactions can be further removed via external pyrophos...

【41 Polymer】 Synthesis and linear rheological property of comb-like styrene-based polymers with a high degree of long-chain branching
A series of model comb-like polymers (PSVS-g-PS) with high branching degree were synthesized by nucleophilic substitution reaction between iodinated copolymer of styrene (St) with 4-(vinylphenyl)-1-butene (VSt) (PSVSI, backbone) and living polystyrene lithium (PSLi, side chain). This method is a facile way for modular synthesis of graft copolymers based on living anionic polymerization and hydrozi...
