“…As a result, the utilization of traditional aliphatic and aromatic polyamide wear-resistant materials with poor heat resistance and mechanical properties has become restricted. 2 However, poly (decamethylene terephthalamide) (PA10T), a semi-aromatic polyamide, offers a solution. With its molecular chains comprising both benzene rings and aliphatic chain segments, PA10T surpasses both aliphatic and aromatic polyamides in terms of heat resistance, mechanical performance, processing capabilities, and reduced water absorption.…”

In an attempt to enhance the properties of biobased semi‐aromatic polyamide poly (decamethylene terephthalamide) acid (PA10T), the effects of different proportions of fillers [MoS2 and polyfluoroalkoxy (PFA)] were investigated. A range of stable and wear‐resistant composites, with filler contents varying from 0 to 10 wt%, were successfully prepared using a one‐step extrusion blending method. To analyze the chemical structures, Fourier transform infrared spectroscopy (FT‐IR) experiments were conducted. Additionally, SEM, tribological tests, differential scanning calorimetry (DSC), x‐ray diffraction (XRD), thermogravimetric analyzer (TGA), tensile measurement, notched impact test, and bending test were employed to thoroughly evaluate the properties of both PA10T and composites. The findings demonstrated that the target products were effectively created, and the composites with fillers exhibited superior wear resistance. Alongside this, they showcased comparable heat resistance and mechanical properties to the pure PA10T. Of particular note, when 4 wt% PFA and 6 wt% MoS2 were added, the specific wear rate of PA10T‐F4M6 (0.0016 mg·min−1) was impressively reduced by 86.2% in comparison to pure PA10T (0.0116 mg·min−1). This reduction in wear mass from 0.7 mg (PA10T) to 0.1 mg (PA10T‐F4M6) further confirms the improvement in wear resistance. Ultimately, these results suggest that composites, with their exceptional wear resistance, hold great potential as heat‐resistant engineering thermoplastics in future applications. Thus, they offer promising prospects for wider utilization across various fields. In essence, this study provides valuable insights into the beneficial impact of MoS2 and PFA fillers on polyamide wear resistance.Highlights The biobased poly (decamethylene terephthalamide) acid (PA10T) was synthesized through an efficient one‐pot melt polymerization method. The composites with excellent performance were prepared by blending the biobased semi‐aromatic polyamide PA10T with unique fillers (MoS2 and PFA) for modification. When 4 wt% PFA and 6 wt% MoS2 were added, the specific wear rate of composites was impressively reduced by 86.2% in comparison to pure PA10T. The addition of fillers (MoS2 and PFA) not only improves the wear resistance of PA10T but also enhances its crystallization properties and melting points effectively. The bending modulus of wear‐resistant composites increased to 1553.66 MPa, representing an approximately 50.47% increase compared to PA10T.

Polyethylene glycol (PEG) is a widely available and environmentally friendly phase change material known for its high energy storage capacity. However, its application in various industries is limited due to slow heat absorption and release, poor mechanical properties, and inadequate weather resistance. PEG was blended with waterborne epoxy resin (WER) to improve its mechanical properties and weather resistance. Furthermore, graphene nanoplatelets (GNPs) and boron nitride (BN) were incorporated into the WER/PEG resin substrate to prepare WER/PEG/BN@GNP coatings, resulting in enhanced thermal conductivity. When the GNP content was 0.5 wt%, the WER/PEG/BN@GNP coatings performed excellent anti‐corrosion. Otherwise, the leakage of PEG under heat‐cool cycling was addressed by the preparation of WER/PEG/BN@GNP coatings, as well as the low rates of heat absorption and release. In this work, the preparation method successfully combines the phase‐change characteristics of PEG, the outstanding mechanical properties of WER, and the high thermal conductivity of BN and GNP. The WER/PEG/BN@GNP coatings present significant potential for practical applications.Highlights A new coating is prepared by incorporation of BN/GNP into PEG/WER matrix. The prepared coating performs phase change and good heat conduction efficiency. The phase‐transition leakage of PEG is resolved by the combination with WER. The synergy of BN and GNP fillers can enhance thermal conductivity effectively. The prepared coating exhibits insulation and anti‐corrosion at low GNP content.

“…The operating environment of polymeric materials has a significant impact on their strength and durability. Aging is associated with changes in the characteristics of the polymer material due to factors such as UV radiation [36][37][38], temperature and its variation [39][40][41][42][43], humidity/water environment [44][45][46][47][48][49][50][51], chemical agents [52][53][54][55] or simply long storage time [56]. Long-term exposure to atmospheric factors can lead to a reduction in their tensile, compressive and bending strength, etc.…”

The aim of this research was a comparative analysis of selected mechanical properties of epoxy compounds that were modified with metallic fillers and aged in aqueous environments. The tested epoxy compounds consisted of three components: styrene modified epoxy resin based on Bisphenol A, triethylenetetramine curing agent (resin/curing agent ratio of 100:10) and two types of metallic fillers in the form of particles: aluminum alloy (EN AW-2024–AlCu4Mg1) and tin-phosphor bronze (CuSn10P). Samples were subjected to ageing in 4 water environments: low-, medium- and high-mineralized natural water and in a sugar-containing solution for 1, 2 and 3 months. The epoxy samples were subjected to compressive strength tests in accordance with the ISO 604:2002 standard. It was observed that, among others, the compositions seasoned in low-mineralized water usually achieved the highest average compressive strength. As for filler type, using the bronze filler (CuSn10P) usually achieved the highest average compressive strength results.
