A homogeneous dispersion of hexagonal boron nitride nanosheets (BNNSs) in elastomers is obtained by solution compounding methods, and a high orientation of BNNSs is achieved by strong shearing. The composites show high thermal conductivities, especially when BNNS loading exceeds 17.5 vol%, indicating that the material is promising for thermal-management applications which need high thermal conductivity, low dielectric constant, and adequate softness.

In this paper, graphene oxide/styrene-butadiene rubber (GO/SBR) composites with complete exfoliation of GO sheets were prepared by aqueous-phase mixing of GO colloid with SBR latex and a small loading of butadiene-styrene-vinyl-pyridine rubber (VPR) latex, followed by their co-coagulation. During co-coagulation, VPR not only plays a key role in the prevention of aggregation of GO sheets but also acts as an interface-bridge between GO and SBR. The results demonstrated that the mechanical properties of the GO/SBR composite with 2.0 vol.% GO is comparable with those of the SBR composite reinforced with 13.1 vol.% of carbon black (CB), with a low mass density and a good gas barrier ability to boot. The present work also showed that GO-silica/SBR composite exhibited outstanding wear resistance and low-rolling resistance which make GO-silica/SBR very competitive for the green tire application, opening up enormous opportunities to prepare high performance rubber composites for future engineering applications.

CsPbIBr2 photovoltaic materials attract remarkable attention in the field of all‐inorganic halide perovskite solar cells (HPSCs) due to their superior humidity stability and heat endurance. Since the first report in 2016, the power conversion efficiency (PCE) of CsPbIBr2‐based HPSCs (Cs‐HPSCs) has increased from 4.7% to 11.53% with an almost 2.5‐fold leap in a short time. Cs‐HPSCs have also become one of the most researched materials in the all‐inorganic perovskite family. Here, the crystal structure and spectrum properties of CsPbIBr2 are first elucidated to provide a preliminary overview. Subsequently, significantly modified strategies, including various assisting procedures for spin coating, interface engineering, and element impurity doping for superior perovskites and better‐performing cells are meticulously introduced. Overall, the development process of the CsPbIBr2 materials is focused on, and the feasible strategies to improve fabrication techniques for superior perovskite films and corresponding device PCEs are emphatically summarized, with the aim to provide some constructive guidelines for the rapid development of Cs‐HPSCs.
