“…Al 2 O 3 -coating layer on polymer surface is known to exhibit excellent adhesion and surface mechanical properties. [50][51][52][53][54] Moreover, the sputtering process is advantageous for enabling a nanoscale coating layer, which does not affect the thickness of the subsequent SE membrane. After sputtering, the ARS was mechanically perforated by applying pressure to the perforation tool shown in Figure S2.…”

“…Rather than the traditional slurry coating method, the ARSs were fabricated by sputtering Al 2 O 3 nanoparticles onto a 5-μm PE membrane to minimize the coating thickness to nanometers. [50][51][52][53][54] The enhanced adhesion and thermal stability of ARSs in SE membranes were verified by surface and interfacial cutting analysis system (SAICAS) and thermal shrinkage tests, respectively. To demonstrate the practical application, we extensively evaluated the electrochemical functionality of an ARS-based SE membrane in LiNi 0.7 Co 0.15 Mn 0.15 O 2 (NCM711)jjLi full cells.…”

Solid electrolytes (SEs) play an essential role in the development of all‐solid‐state batteries (ASSBs) due to their exceptional ionic conductivity. However, conventional pelletized SEs with hundreds of micrometers result in highly reduced energy density and suffer from mechanical brittleness, which delay the commercialization of ASSBs. In this study, we present an innovative approach to fabricate SE membranes with perforated Al2O3 nanolayer‐coated polyethylene (PE) separator as a mechanical supporter. Al2O3‐coated separators exhibit better adhesion with LPSCl particles and better thermal stability. As a result, the SE membrane exhibits thickness of 35 μm while maintaining a superior mechanical tensile strength. Furthermore, when the SE membrane is applied to Li||LiNi0.7Co0.15Mn0.15O2 full‐cells, stable cycling performance over 250 cycles, which is comparable to thick LPSCl pellet cell, can be achieved even with higher conductance (>150 mS). Our results highlight the potential of thin and durable SE membranes in contributing to the commercialization of ASSBs.

“…To address poor interfacial adhesion in natural fibre reinforced composites caused by their hydrophilic nature, surface modification treatments like alkalisation, acetylation, bleaching benzoylation, and silane have been used to enhance reinforcement-matrix interfacial adhesion by eliminating the amorphous surface layer from the fibre and enhancing the physical strength of the fibres [10][11][12]. There is a need to review how different researchers have investigated the effect of these different surface modification techniques in natural fibres and the results they attained to enhance qualities like thermal stability, mechanical properties as well as natural fibre hydrophobicity.…”

The use of natural fibres in fibre-reinforced composites comes with drawbacks. They are highly hydrophilic, leading to high moisture absorption and poor interfacial adhesion in matrix-reinforcement bonds. This affects the fibres’ thermal stability as well as mechanical properties, hence limiting their wider application. This paper reviewed different ways in which natural fibres have been treated to improve hydrophobicity, reinforcement-matrix interfacial adhesion and thermal stability. It will investigate. among others, treatments like alkali, acetylation, bleaching, silane, benzoylation and plasma, which have been found to improve fibre hydrophobicity. The literature reviewed showed that these methods work to improve mechanical, chemical, and morphological properties of natural fibres by removing the amorphous surface, thus allowing for more efficient load transfer on the fibre-matrix surface. Studies in the literature found alkali treatment to be the most common surface modification treatment due to its simplicity and effectiveness. However, plasma treatment has emerged due to its lower processing time and chemical consumption. A comparative analysis of other improved properties was also investigated.

A series of wholly carborane‐containing polyesters with high thermostability were successfully synthesized by the catalytic polycondensation of carborane diol monomers with carborane diacid chlorides. They can be used for the preparation of materials of high temperature resistant coatings and adhesive. The influence of solvent, reaction temperature, and reaction time on the molecular weight and yield of the polymers were studied. In comparison with the carborane‐free polyester, the carborane‐containing polyesters showed higher degradation temperature and char yield and lower degradation rate. The thermal gravimetric analyzer (TGA) curves indicate that the carborane group could effectively reduce the degradation rate of carborane‐containing polyesters, which give a char yield of exceeding 64% under air (47% under N2) at 700 °C. Such data are superior to the carborane‐free polyester, which showed a low char yield of around 0.3% under air (5% under N2) at the same condition. Moreover, the thermal transition mechanism of carborane‐containing polyesters was also studied. The FTIR spectra and TG‐FTIR analysis indicate that the carborane cage could react with oxygen to form BOB and BC linkages at elevated temperatures, which postpones the thermal decomposition of polyester and accounts for the high char yield. The newly prepared kind of high temperature polyesters have enormous technical and economic value, especially in the high temperature fields. They can be widely used as raw materials to prepare the high temperature resistant coatings or adhesives for automotive engine, aircraft and other equipments worked in high‐temperature environments. Under high environmental temperature, the good thermal stability is capable of keeping polyesters stable and expanding their service lives. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.
