“…When it was combined with fluorine resin to form coatings, due to the influence of surface shape, particle size, surface wetting agent, and solvent in the coating system, there were many pores between resin and carbon black, which affected the compactness of the whole coating. The more carbon black that was added, the more serious the defect between the resin and carbon black was, which affected the resistance of the coating to moisture and oxygen permeation [24]. The mechanical properties, optical properties, and infrared spectroscopy tests showed that the black paste yielded better properties when its content was 0%-3.0%.…”

A fluorine resin/aluminum infrared coating was prepared with aluminum using black paste as filler and fluorine resin as binder. The effect of the black paste content on the performance of gloss, color difference, infrared emissivity, hardness, adhesion, impact resistance, roughness, optical testing, and corrosion resistance of the fluorine resin/aluminum infrared coating were examined. When the content of black paste was increased from 1.0% to 9.0%, the gloss of the coating surface decreased; the ΔE* value of the coating decreased; the infrared emissivity of the coating surface increased gradually; the hardness of the coating was 6H; the adhesion grade of the coating was 0; the infrared absorption peak increased gradually. When the content of black paste was 0%–3.0%, the impact resistance was more than 50 kg∙cm, and the impact resistance was higher. When the content of black paste was 0%–5.0%, the surface roughness of the coating was relatively low. When the content of black paste was 1.0%, the corrosion resistance of the coating was the best. The results showed that when the content of black paste was 1.0%, the performance of the whole fluorine resin coating was the best. Through the preparation and characterization of fluorine resin infrared low-emissivity coatings, the possibility of applying fluorine resin to infrared low-emissivity anticorrosive coatings was discussed, which laid a foundation for the subsequent engineering application of coatings.

With the trend of integration and miniaturization of stretchable electronics, thermal management has been a crucial issue. Developing novel materials with high thermal conductivity (TC) and flexibility is urgent. Herein, we report a stretchable polydimethylsiloxane (PDMS)/boron nitride nanosheet (BNNS)@spherical aluminum oxide (Al2O3) composite with high TC and electrical insulation prepared by a two‐step strategy of sucrose‐template and hot‐pressing. An effective foam‐pressing route benefits the composites to form a three‐dimensional thermally conductive networks, improving the in‐plane TC value of the resultant composite to 4.03 W/(mK) at the filler mass fraction of 35.7 wt% and enhancing to 4.66 W/(mK) under 40% stretching ratio. Meanwhile, the composites can be restored to their former state and retain thermally conductive stability with repeated bending and twisting tests. Moreover, the composites were applied in LED with stretching, exhibiting good heat dissipation performance. These results demonstrate this PDMS composite can be potentially utilized as a high‐performance material to solve thermal management problems in flexible electronics.Highlights The heat conduction network is prepared by sucrose‐template and hot‐pressing. BNNS@P‐Al2O3 fillers are self‐assembled via the electrostatic interaction. The composites exhibit good thermal conduction and superior flexibility. The thermal conductivity of the composite increases after stretching. The composites can retain thermal conductive stability after deformation.

“…Silicone rubber possesses the environment friendly, excellent fatigue resistance, excellent aging-resistance, and wide working temperature range, which has been extensively applied to manufacture flexible sensor products. [23][24][25][26][27][28] But most studies deals with wet-processing of CNTs in silicone rubber involving organic liquids to avoid their damage, making them difficult and cumbersome for industrial production. [29] So the technology challenges always maintain for improved dispersion and less damage of SWCNTs through dry processes.…”

Conductive, sensing stable and mechanical robust silicone rubber composites for large‐strain sensors

Conductive polymer composites (CPCs) with carbon nanotubes (CNTs) have exhibited desirable sensing capacities to external stimuli. In this study, it is found that poor dispersion of single-wall CNTs gives rise to low mechanical strength and unsteady responsive signal outputs of CPCs as strain sensing materials. With attempt to solve this problem, we prepare the conductive silicone rubber composites with hybrid CNT masterbatch and carbon black (CB) fillers (CNT/CB composites) by drying mixing method. Hybrid CBs separate and loosen the entanglement of CNTs in CNT/CB composites which forms more conductive paths and better dispersion of CNTs than those only with single CNTs (CNT-composites). CNT/CB composite achieves a good conductivity, sufficient mechanical strength and high elasticity. In contrast with CNTcomposite, its reproducibility of resistance responsivity was remarkably improved at strain cycles, which display stable sensing properties for mechanically strain sensor applications. Importantly, CNT/CB composites show outdoor usage robustness, including excellent salt-spray resistance, hot-humidity stability and a wide operation temperature range of À40 to +50 C. It is believed that our work offers a simple approach to fabricate stable and flexible strain sensing materials, which is useful for sensor products.
