Improving the Thermal Properties of Polycarbonate via the Copolymerization of a Small Amount of Bisphenol Fluorene with Bisphenol A

open access: yesInternational Journal of Polymer Science, 2022
Polycarbonate is an attractive transparent plastic with high mechanical/thermal properties. A family of copolycarbonates of bisphenol-A (BPA), 9, 9-bis (4-hydroxyphenyl) fluorene (BHPF), and diphenyl carbonate (DPC) were prepared by a transesterification

Effect of pretreatment on microstructural stability and mechanical property in a spray formed Al-Zn-Mg-Cu alloy

open access: yesMaterials & Design, 2021
Aluminum alloys fabricated by spray forming (SF) technology are commonly followed by hot-working without heat treatments. A new approach that is a pretreatment before hot-working is proposed in the present work.
