چکیده

Developing polymer-based nanocomposites with high thermal conductivity, mechanical performance, and electrical insulation becomes a huge challenge in both academia industry. In this article, the synergistic effects of boron nitride (BN) nanosheets carbon nanotubes (CNTs) on properties conductivity epoxy nanocomposite adhesives were investigated. The results showed that addition one-dimensional CNTs two-dimensional BN into matrix contributes to formation three-dimensional network larger contact surface between nanofillers matrix. hybrid filler provided significant improvements adhesives. At 1.06 vol% BN-CNTs, provide higher Young's modulus, fracture toughness (K1C), energy release rate (G1C), lap shear strength, stability compared epoxy/BN epoxy/BN-CNT recorded its maximum values 0.49 K m?1 k?1 at 3.79 increased by 335% 133% case same fraction vol%.

Ultra-high thermally conductive and rapid heat responsive poly(benzobisoxazole) nanocomposites with self-aligned graphene.

Self-alignment of thermally reduced graphene sheets (TRG) that enable highly efficient heat transfer paths in their poly(p-phenylene benzobisoxazole) (PBO)-based nanocomposite films along the in-plane direction was achieved for the first time without any assistance of an external magnetic or an electric field. In the in-plane direction, the nanocomposite films possess an ultra-high thermal diff...

Electrically conductive epoxy nanocomposites containing carbonaceous fillers and in-situ generated silver nanoparticles

An epoxy resin was nanomodified with in-situ generated silver nanoparticles (Ag) and with various amounts of carbon black (CB) and carbon nanofibers (NF), in order to increase the electrical conductivity of the matrix. Differential scanning calorimetry tests revealed how the addition of both CB and NF led to a slight decrease of the glass transition temperature of the material, while electron m...

Flexible and conductive MXene films and nanocomposites with high capacitance.

MXenes, a new family of 2D materials, combine hydrophilic surfaces with metallic conductivity. Delamination of MXene produces single-layer nanosheets with thickness of about a nanometer and lateral size of the order of micrometers. The high aspect ratio of delaminated MXene renders it promising nanofiller in multifunctional polymer nanocomposites. Herein, Ti3C2T(x) MXene was mixed with either a...

Preparation and properties of electrically conductive PPS/expanded graphite nanocomposites

Nanocomposites based on poly (phenylene sulfide) (PPS) and expanded graphite (EG) or ultrasonicated EG (S-EG) were prepared by melt blending. Morphologies of the nanocomposites were examined using both SEM and TEM. Electrical conductivity and thermal stability of PPS were notably enhanced by the introduction of EG. The percolation threshold values are 1 wt% (S-EG) and 2 wt% (EG) for PPS/S-EG an...

Electrical conductive CNT-PVA/PC nanocomposites with high tensile elongation.

Electrically conductive CNT reinforced polycarbonate matrix nanocomposites with high strain-to-failure were fabricated by inserting polyvinylalcohol as a surface modifier through a melt blending process. The addition of PVA by coating the CNT through a simple ball milling process before melt blending with a polycarbonate matrix resulted in an increased percolation limit as compared to that prep...
