“…For example, polymer matrices 4 are often used in composites for their flexibility and low weight, while ceramic matrices 5 are preferred for their high strength and resistance to extreme temperatures. 6 Composites possess unique properties 7,8 such as strength, weight, corrosion resistance, hardness, high-temperature performance, and conductivity that are not achievable in individual components. The effectiveness of composites is influenced by various factors including the amounts of components, 9 the degree of bonding between additives and fillers, particle size, shape, and distribution.…”

In this investigation, the examination revolves around the characterization of diatomite-enhanced modified safflower oil (MSO)-derived polyester biocomposites. The primary objective is to explore the feasibility of these biocomposites as a substitute for petrochemical-based unsaturated polyester (UP) materials, with the overarching goal of enhancing their economic sustainability. Experimental data analysis employed Response Surface Methodology (RSM) and Artificial Neural Network (ANN), uncovering the optimal composition for the polyester biocomposite to be 6.7 wt.% MSO and 4.5 wt.% diatomite. During the RSM analysis, it was noted that the response parameters exhibited quadratic p-values, specifically, for density ( p < .0001), thermal conductivity ( p < .0001), and Shore D hardness ( p < .0003). However, higher ratios of MSO lead to decreased hardness and increased curing time. SEM images reveal a detrimental impact on the surface morphology of the polyester biocomposite when the diatomite content reaches 8 wt.%. Additionally, Fourier Transform Infrared Spectroscopy (FTIR) and Thermogravimetric Analysis (TGA) offer valuable insights into the chemical bond structure and thermal behavior of the biocomposite, respectively. The Cure Index (CI) value for the diatomite-enhanced composite was determined to be 0.925, indicating a favorable contribution to the polyester curing process. The study finds that diatomite contributes to a linear change in the thermal conductivity coefficient, making the biocomposite suitable for use in the insulation industry. Overall, the study suggests that diatomite reinforced MSO-based polyester biocomposites have the potential as an alternative to petrochemical unsaturated polyester.

“…As there is no association observed for mechanical and tribological performance, the wear characteristic of the epoxy due to change in nanoparticles is addressed in this section. In recent methods, it is observed that the nanocomposite flled with nanoparticles are more uniform in coating surfaces compared to existing coating additives [29,30] for abrasion resistance. Whereas, it is observed that large particles are more suitable in protecting the polymer matrix if not been removed [20].…”

This research work developed a method for the analysis of epoxy matrix nanocomposites used in epoxy resin with the incorporation of Al2O3 and SiO2 nanoparticles. The different tests were performed in order to derive the mechanical characteristics and wear properties of Al2O3 and SiO2 nanoparticles. The mixing is performed using an ultrasound process where the nanoparticles are mixed with the resin for a homogeneous diffusion. The strengths observed for the nanocomposite were higher for bending and impact strength because of the Al2O3 and SiO2 nanoparticle incorporation. The wear rate and friction coefficient is observed to be reduced due to the incorporation of Al2O3 and SiO2 nanoparticles into the epoxy resin. This characteristic has a significant benefit of using Al2O3 and SiO2 nanoparticles for loading conditions. The effects of Al2O3 and SiO2 nanoparticles were more effective in epoxy resin, which were more effectively been derived by reinforcing methods.

This research paper presents the fabrication of epoxy coatings along with the hybrid combination of SiO2 and ZrO2. The epoxy resin is incorporated with SiO2 as the primary pigment and ZrO2 as the synergist pigment. The study delves into the adhesion, barrier, and anti-corrosion properties of these coatings, enriched with silica and zirconium nanoparticles, and investigates their impact on the final properties of the epoxy coating. The epoxy resin, a Diglycidyl ether bisphenol-A (DGEBA) type, is cured with a polyamidoamine adduct-based curing agent. To evaluate the protective performance of silica SiO2 and zirconia ZrO2 nanoparticles in epoxy coatings, the coated samples were tested in a 3.5% NaCl solution. The experimental results clearly demonstrate a remarkable improvement in the ultimate tensile strength (UTS), yield strength (YS), and Elastic Modulus. In comparison to using SiO2 separately, the incorporation of both ZrO2 and SiO2 resulted in a substantial increase of 43.5% in UTS, 74.2% in YS, and 8.2% in Elastic Modulus. The corrosion test results revealed that the combination of DGEBA, SiO2, and ZrO2 significantly enhanced the anti-corrosion efficiency of the organic coatings. Both these pigments exhibited superior anti-corrosion effects and mechanical properties compared to conventional epoxy coatings, leading to a substantial increase in the anti-corrosion efficiency of the developed coating. This research focuses the potential of SiO2 and ZrO2 in hybrid combination for applications, where mechanical, corrosion and higher adhesion to the substrates are of prime importance.
