Abstract null null The rapid development of electronic devices has led to widespread demand and research on electronic packaging materials with electromagnetic shielding and thermal conductivity (TC) properties due to the inevitable issues of the electromagnetic radiation and thermal accumulation. However, there exists a huge challenge to simultaneously achieve high electromagnetic shielding and TC as well as the electrical insulation requirement as electromagnetic shielding predominantly relies...

Abstract null null Graphene (G) has spectacular impermeability and chemical stability, holding promise as an excellent anticorrosion filler, and previous studies supports this hope. However, G only shows limited corrosion inhibition and even corrosion enhancement due to its inherent conductivity and uncontrolled distribution. Natural nacre provides an inspiration for constructing highly aligned structure coatings, in which G sheets are spatially isolated and keep 2D states. To realize the reliab...

Abstract null null Polytetrafluoroethylene/multiwalled carbon nanotubes (PTFE/CNT) nanofiber membranes were prepared by emulsion electrospinning and high temperature sintering. Compared with pure PTFE nanofiber membranes, at low CNT content, the mechanical properties of PTFE/CNT nanofiber membranes were improved. For example, the tensile strength of PTFE/CNT (0.5 wt%) composite nanofiber membranes increased from 2.5 MPa to 5.92 MPa, and the elongation at break increased from 123% to 330%. The co...

Abstract null null Carbon nanotubes (CNTs) have been considered as promising reinforcements for various composites due to their excellent mechanical properties. However, preparation of high-performance CNT/resin composites still suffers from bad dispersion, low fraction, and poor alignment of CNTs and their weak bonding with the resin matrix. Herein, we report an effective strategy towards preparing CNT/Bismaleimide (BMI) composite films with excellent mechanical properties. Firstly, from floati...

Abstract null null Interfacial transition zones (ITZs) of cementitious concrete are highly heterogeneous, which cause many challenges in accurately obtaining their properties. In this paper, regular aggregates were applied to prepare modelled geopolymer composites, in which ITZs exhibited neat boundaries. Nanoscratch technique with the ability to quickly scan a long distance was adopted to investigate mechanical properties of ITZ and geopolymer paste. To compare the properties of the ITZs and pa...

Abstract null null Considering the balance between rapidly growing global tire demand and scarcity of natural resources, recycling and reclaiming techniques of tire rubber have become the state of the art. Herein, we set out to implement a self-designed thermo-oxidative reactor for the exfoliation of carbon black (CB) from ground tire rubber, which is efficiently functioned under a thermo-oxidative reclaiming condition without any additive. The exfoliation of CB from rubber vulcanizate was reali...

Abstract null null Morphological transformation only occurs in polymer blends via changing their components, which can be utilized to form double percolation structures. However, the weight percentage of either polymer in the blend generally ranges from 40 wt% to 60 wt%, which does not favor the construction of a densely conductive path. Herein, a double percolation structure had been successfully constructed in a polylactide-polycaprolactone (PLA/PCL) blend with only 30 wt% PCL by adding silico...

Abstract null null There is a complex nonlinear dynamic coupling and multi-physical damage between lightning channel and composite material. This paper aims to study the coupling mechanism between lightning channel and composite material. Magneto Hydro Dynamics (MHD) model is established to describe physical characteristics of lightning channel. Moving mesh approach and interface tracking method are applied to deal with the dynamic damage of composites material exposed to lightning channel. This...
Abstract null null The influence of fumed silica as reinforcement filler is investigated on the Mullins stress softening in composite silicone elastomers. Especially, the impact of surface area, loading level, surface chemistry, and structure modification of fumed silica is evaluated on the fatigue behavior of high consistency silicone rubber. It is observed that high loading level and large surface area of fumed silica increase the energy loss during initial loading cycles which is related to d...
