Progress in recycling and reutilization of waste polyethylene terephthalate

Progress in Rubber Plastics and Recycling Technology (2023)

Ruixin Chen Sai Deng Tongyan Cui Shiyu Duan Qingxiu Jia

Polyethylene terephthalate (PET) is a versatile material with a wide range of applications, and the demand for PET products has been steadily increasing in recent years. This has generated large quantities of non-biodegradable PET waste. To reduce environmental pollution, recycling and reuse of waste PET is an economical solution. Different PET products vary greatly in their impurity contents, processing technology, and performance, which poses certain challenges for the recovery, purification, and reuse of PET waste in a high value-added manner. Various recycling and reutilization methods are compared, potential issues with different PET products in the recycling process are analyzed, and viscosity enhancement modification techniques and applications of recycled PET are introduced. This paper provides a reference for the recycling of various waste PET products.

Synthesis of Stable Cs-Rich FA-Cs Perovskite Solar Cells by Assistance of a Lewis Base Additive

ACS Applied Energy Materials (2024)

Shiyu Duan Nan Tian Jicheng Zhang Zhaoxuan Huang Disheng Yao

Cs-rich FA-Cs perovskites theoretically have good humidity stability, photothermal stability, and suitable band gap for top cells of tandem solar cells. However, the phase separation of Cs-rich FA-Cs perovskite films occurs when the Cs content exceeds 30%, so it is difficult to synthesize pure Cs-rich FA-Cs perovskite films. Here, pure Cs-rich FA-Cs perovskite Cs1–xFAxPbI2Br(0 ≤ x ≤ 0.6) films without any impurity phase are first synthesized by reducing its phase formation energy barrier through assistance of PbI2(DMSO) and PbBr2(DMSO) admixtures. Compared with the pristine CsPbI2Br films, the humidity stability of those films is significantly improved and a remarkably enhanced power conversion efficiency (PCE) of 14.55% in α-Cs0.7FA0.3PbI2Br solar cells is achieved. Meanwhile, after annealing at 140 °C for 1 h or irradiating with ultraviolet light in N2 or dry air for 12 h, no phase separation and band gap change are found in Cs0.7FA0.3PbI2Br. The distributions of the PCE are similar, and the champion PCE of the corresponding Cs0.7FA0.3PbI2Br solar cells remains within 14.24–14.55%. This shows that α-Cs0.7FA0.3PbI2Br has good thermal and ultraviolet radiation stability.

Research progress on sustainability of key tire materials

SusMat (2023)

Sai Deng Ruixin Chen Shiyu Duan Qingxiu Jia Xinmin Hao

Abstract In recent years, countries worldwide have engaged actively in the research and development of green and sustainable materials in the face of the increasing depletion of petroleum resources, the need to reduce material waste, and the environmental pollution caused by the various types of waste. In the tire industry, the key materials for the various components of tires are mostly dependent on petroleum resources. Development of green tires and green processing technologies using sustainable materials is an important development direction for the future of the tire industry, and many tire‐manufacturing companies have proposed their visions for the development of eco‐friendly tires. Rubber, cord fabric, and additives are the main materials used in tire manufacturing. This article summarizes the research status of the green materials that can meet the requirements of environmental friendliness and sustainability, replace traditional materials, and reduce petroleum resource consumption in existing tire production. These materials mainly include natural rubber or bio‐based synthetic rubber, green renewable cord fabrics, and green processing additives. The prospects for the application of these new green materials in tire manufacturing are also discussed.
