“…When compared with silane coupling agents, these long‐chain fatty acids, that is, stearic, palmitic, and ester FP, LA has been found to render efficient coupling action at a lower percentage that is, at 2 wt %. LA (RFALA2) showed the highest enhancement in the flexural modulus values (4535 MPa) when compared to our previous reports, where 1 wt % SA‐ and PA‐coated FA/R and 2 wt % FP‐coated FA/R composites showed flexural modulus values of 4294, 4522, and 3054 MPa, respectively …”

“…These fatty acids, having carbon chain lengths of 16 (PA, FP) and 18 (SA) were observed to have considerable influence on the filler/matrix interface and to have reoriented the crystalline arrangement of the polymer chains and modified the structural properties of the composites. The use of 1–2 wt % of these fatty acids as a coupling agent in FA/R composites showed improvements in the mechanical and thermal properties …”

Sustainable composites were developed from fly ash (FA) and recycled polypropylene (R) with lauric acid (LA) as the coupling agent. The FA particles were surface-coated with 1, 2, 3, and 5 wt % LA, and the coating on the FA particles was verified by transmission electron microscopy and Fourier transform infrared spectroscopy. R and LA-coated FA particles were melt-mixed in a 1:1 weight ratio to achieve a high-filler-loaded composite. The flexural, impact, nanoindentation, and fracture surface analyses were carried out to examine the properties of the composites. The flexural strength and modulus values increased in the 2 wt % LA-coated FA/R composites by 6 and 50%, respectively, compared to the values of the uncoated FA/R composites, whereas the impact strength increased considerably by 119% in the 1 wt % LA-coated composites. Nanoindentation tests also showed an increase in the mechanical properties in the case of the 1 and 2 wt % LA-coated composites in comparison to the uncoated ones. Fracture surface studies done by scanning electron microscopy revealed improved interfacial interactions between the filler and matrix in the presence of the LA coupling agent. X-ray diffraction (XRD) studies indicated reorientations of the polymer chains in the presence of different concentrations of the LA coupling agent; this resulted into different crystallinities and crystallite sizes. Differential scanning calorimetry showed a significant difference in the crystalline peaks of the composites, and this corroborated well with the XRD observations. LA, thus, significantly influenced the structural properties of the composites, and this, in turn, influenced their mechanical and thermal properties.

“…Fly ash has been used widely as reinforcement in polymer matrix composites and it was earlier used in various polymers, such as polyetheretherketone [7], polypropylene [8,9], epoxy [10], poly(vinyl alcohol) [11], and high density polyethylene (HDPE) [12] and ethylene-octene copolymer (EOC) [13].…”

Class-F fly ash (FA) from a coal-fired thermal power station was subjected to high energy ball millinginduced mechanochemical activation aided by a surfactant. Subsequently, ethylene-octene copolymer/mechanochemically activated FA (EOC/MCA-FA) composites were prepared by solution casting. The surface modification of FA was confirmed from contact angle measurements and FTIR spectroscopy, which accounts for a good interaction between MCA-FA and the polymer matrix. X-ray diffraction reveals that the crystalline size of quartz phase present in FA got reduced, while the relative lattice strain on it increased during milling. Morphological studies revealed that interfacial adhesion between the polymer and MCA-FA is good and this accounts for the improvement in mechanical properties of the composites even at the minimum filler loading. Flame retardance of the matrix polymer is improved by the addition of either fresh FA or MCA-FA. The results imply that FA is a valuable reinforcing filler for ethylene-octene copolymer and its mechanochemical activation is an effective strategy for its future use.

“…The densities and compressive strengths of the composites increased as a function of their FA content; the% shrinkage and water absorption decreased with increased FA loading. Sengupta et al [7] prepared composites from recycled polypropylene and furfuryl palmitate-modified FA. Anandhan et al [12] developed composites from EOC and unmodified as well as surfacemodified class-F FA (MFA) by twin screw extrusion.…”
