“…The recycled is XLPE foam was used as the core component of the hybrid material. 31,32 The closed-cell structure of XLPE foam traps air inside the material, giving it outstanding thermal insulation capabilities. 33 Its poor heat conductivity means that less heat will move through the material.…”

This research discusses the development of a high performance composite out of waste plastic that is ultralightweight, thermally insulated, and high impact resistant. Polycarbonate sheet and Cross-linked Polyethylene (XLPE) foam were combined to create the composite, and silicon adhesive was used to fabricate the composite. Polycarbonate sheets are high impact resistant material, high thermal insulation is provided by XLPE foam, and silicon adhesive is used because of its low thermal conductivity. The composite was fabricated using a stacking technique. The composite prototype was then evaluated by experimenting it to dry ice at a temperature of −78.6°C. Drop tests, compression tests, density measurements was carried out, and thermal analysis was carried out using thermogravimetric analysis. The sample can endure low temperatures while maintaining room temperature on the other side, according to a 24 h dry ice test, whilst a drop test demonstrated that it can withstand significant impact loads. A numerical simulation using Abaqus/Explicit was also used to validate the variations in temperature between the outside surface at −20°C and the inside surface maintained at 30°C of the composites when exposed to cold temperature. The result reveals that the hybrid composite are highly promising in terms of thermal insulation.

“…43 The market demand for high-quality polyethylene foam is continuously increasing, particularly with the development of the construction industry and e-commerce. 44 Regrettably, waste disposal would become a problem because the polymer does not decompose, 45,46 leading to dire consequences such as global climate change and environmental pollution commonly referred to as "white pollution". 44 Traditional incineration of waste plastics increases CO 2 emissions, while landfilling them takes up land resources and may lead to secondary pollution.…”

Interfacial solar steam generation for sustainable and eco-friendly desalination and wastewater treatment has attracted much attention. However, costly raw materials and complex preparation processes pose constant challenges to its wide promotion. Herein, a novel, cost-effective, and scalable strategy is presented for preparing solar interface evaporators using industrial waste as a raw material. Modified polyethylene foam evaporators (M-EPEs) are simply prepared by drilling and then hydrophilic modification of industrial waste (EPE-1). M-EPEs not only retain the strong mechanical properties and thermal insulating properties (0.047 W·m–1·K–1) of EPE-1 but also exhibit superhydrophilicity and strong light absorption (over 90%). M-EPEs achieve a high evaporation rate of 1.497 kg·m–2·h–1 and photothermal efficiency of up to 93.8% under 1 kW·m–2 solar illumination. Moreover, it has excellent stability and salt tolerance. Our work addresses the environmental issues of recycling polyethylene waste and provides a facile and efficient strategy for designing low-cost, large-scale solar interface evaporators for desalination.

“…Polyethylene (PE) is the most common and widely produced polymer and is extensively used in the electrical, medical, construction, aerospace, and automotive industries. [1][2][3][4] Currently, advanced PE development has shifted from controlling molecular structures to developing high-performance PE commodities. Building desirable crystalline and amorphous hierarchal structures has an effect on the processing technology application of PE.…”

The crystallinity of polyethylene has been extensively studied, but in situ experiments designed to investigate the crystallization of PE and XLPE have hardly been discussed. In this work, the crystallization behavior of PE and XLPE was investigated by designing in situ crystallization observation experiments. We have compared the crystallinity, crosslinking, viscosity properties, and gas byproducts of different XLPE insulating materials. COMSOL simulations demonstrate that the DTAP and DTBP crosslinker initiated crosslinks have better insulating properties and cable stability than the DTBC and DTBTMC crosslinkers. The formation of an insulation layer initiated by the DTAP crosslinker is beneficial for improving the breakdown strength, processing performance, and stable operation of cables. Our work is of great significance for understanding the crystallinity of XLPE and determining the correct crosslinker.Highlights In situ crystallization observation of PE and XLPE.
