Production and Application of Polymer Foams Employing Supercritical Carbon Dioxide Adv. Polym. Technol. (IF 3.1) Pub Date : 2022-12-28 Guilherme M. R. Lima, Ranjita K. Bose
Polymeric foams have characteristics that make them attractive for different applications. However, some foaming methods rely on chemicals that are not environmentally friendly. One of the possibilities to tackle the environmental issue is to utilize supercritical carbon dioxide ScCO2 since it is a “green” solvent, thus facilitating a sustainable method of producing foams. ScCO2 is nontoxic, chemically

PVDF-Based Fluoropolymer Modifications via Photoinduced Atom Transfer Radical Polymerizations Adv. Polym. Technol. (IF 3.1) Pub Date : 2022-12-21 Nuo Xu, Guangyu Pan, Hui Zhang, Peng Lu, Lei Shen, Yuguang Li, Dong Ji, Jindian Duan, Xin Hu, Chunhua Lu, Zhongzi Xu, Ning Zhu, Kai Guo
Graft modifications of PVDF fluoropolymers have been identified as the efficient route to improve the properties and expand the applications. Taking advantage of C-F and C-Cl bonds in the repeat units, atom transfer radical polymerizations (ATRP) were widely used for graft modification. Recently, photoinduced ATRP has shown good spatial and temporal control over the polymerization process in contrast

Novel Synthesis of Polyimide Foams with Aromatic and 1,6-Diaminohexane Imide Bonding Adv. Polym. Technol. (IF 3.1) Pub Date : 2022-12-5 Dong-Sen Chen, Chun-Hua Chen, Wha-Tzong Whang, Chun-Wei Su
A novel type of polyimide foams (PIFs) with chemically inserted flexible aliphatic diamine (1,6-diaminohexane (HMDA)) segments was successfully synthesized and characterized in this research. The aliphatic HMDA segments were randomly incorporated in the long chain aromatic imide bonds. The obtained PIFs containing various HMDA contents (0 to 20 mol%) exhibited different morphologies such as lowered

Solution Uptake in Cylindrical Carbon-Fibre-Reinforced Polymer (CFRP) Tendons Adv. Polym. Technol. (IF 3.1) Pub Date : 2022-11-30 Paul Scott, Eleni Toumpanaki, Janet M. Lees
Salt water exposure conditions relevant to carbon-fibre-reinforced polymer (CFRP) prestressed concrete structures in marine environments are investigated. The diffusion into relatively small diameter CFRP tendons can be a lengthy process so the prediction of the long-term moisture uptake using short-term experiments on thin films of epoxy would be advantageous. However, the fibre inclusions within
