“…This trend is in agreement with the results obtained by Sadequl et al [ 24 ]. In another research by Charoenchai et al [ 18 ], the mechanical properties of neat natural rubber did not show significant change when compared to reinforced rubber composites due to low content of silica used in the system. Sombatsompop et al [ 23 ] concluded that the tensile strength stabilized at 30 phr of silica content and further increment of silica content only increased the crosslink density of the vulcanizates without providing any mechanical enhancement.…”

Natural rubber is of significant economic importance owing to its excellent resilience, elasticity, abrasion and impact resistance. Despite that, natural rubber has been identified with some drawbacks such as low modulus and strength and therefore opens up the opportunity for adding a reinforcing agent. Apart from the conventional fillers such as silica, carbon black and lignocellulosic fibers, nanocellulose is also one of the ideal candidates. Nanocellulose is a promising filler with many excellent properties such as renewability, biocompatibility, non-toxicity, reactive surface, low density, high specific surface area, high tensile and elastic modulus. However, it has some limitations in hydrophobicity, solubility and compatibility and therefore it is very difficult to achieve good dispersion and interfacial properties with the natural rubber matrix. Surface modification is often carried out to enhance the interfacial compatibilities between nanocellulose and natural rubber and to alleviate difficulties in dispersing them in polar solvents or polymers. This paper aims to highlight the different surface modification methods employed by several researchers in modifying nanocellulose and its reinforcement effects in the natural rubber matrix. The mechanism of the different surface medication methods has been discussed. The review also lists out the conventional filler that had been used as reinforcing agent for natural rubber. The challenges and future prospective has also been concluded in the last part of this review.

“…Obtaining silica through alkoxide hydrolysis is a process very well understood. It was the example used in the legendary article by Hench and West [21] (Figure 2), but over the years, the process has been modified to suit any number of needs such as in the production of bioactive powders [28], functionalized silica for the adsorption of metallic ions for environmental purposes [29], silica-zirconia composite membranes for gas separation [30], and silicagraphene oxide nanocomposites for the improvement of mechanical properties of natural rubber [31], amongst other examples. intention of the process is for the metal atom to be surrounded by hydroxyl ions as a result of severing the alkoxide alkyl chain, and in turn, the same hydroxyl ions will be participants of a condensation reaction to join the hydrolyzed metal-containing molecules [26].…”

Surface Enhanced Infrared Absorption Spectroscopy and Surface Enhanced Raman Spectroscopy are analytic techniques that have not been massively adopted since there are issues that still need to be solved with regard to the nature of the signal enhancement substrates used. The sol–gel method for the obtention of ceramics provides an alternative for the production of said substrates. Ceramics are very wear- and heat-resistant, properties that can be used for their regeneration, and through the sol–gel method, ceramics can be produced with high purity as well as can be fashioned in many ways through different techniques, which can be helpful in the pursuit of reproducibility. This paper discusses the different advantages of sol–gel ceramics, their use in the electrospinning technique, and their application in infrared and Raman surface-enhanced spectroscopy.

“…The generated SiO 2 particles can be uniformly dispersed in the rubber latex system, after flocculation, dehydration and drying. [24][25][26] Charoenchai et al 27 used the sol-gel method to prepare SiO 2 /GO/NR composite materials, and successfully coated SiO 2 on the surface of GO, and the SiO 2 /graphene coating can penetrate into the rubber molecular chains. Watcharakul et al 28 used the sol-gel method to enhance NR composites, specifically studying the effects of TEOS concentration, temperature, and reaction time on NR composites.…”

The wear resistance of rubber composite materials has always been the focus of research. The wear resistance will not only affect the service life of products and the safety of equipment, but also have an important impact on the environment. In this work, the preparation and properties of wear-resistant rubber nanocomposites based on natural rubber (NR) were studied. It is dedicated to improving the wear resistance of NR composites. On this basis, the dispersibility of montmorillonite (MMT) hybrid materials in NR-based rubber composites was explored. SiO 2 @MMT, SiO 2 @MMT@KH560, PDA@GO, and MMT@GO hybrid materials were prepared, and the hybrid materials were applied to the NR/butadiene rubber (NR/BR) system, and NR/BR/hybrid material composite materials were successfully prepared. The results show that the interlayer spacing of MMT in hybrid materials increases, which effectively improves the dispersibility of MMT in rubber matrix. The tensile strength of NR/BR/MMT@GO composite material increased by 12%, the elongation at break increased by 25%, the DIN abrasion decreased by 16.5% compared with the optimum wear rubber formula, and the wear resistance was greatly improved. This work provides a feasible way for the design of functional polymer composites.
