Abstract
Abstract This article proposes the preparation and microwave thermal cured (MTC) epoxy-modified phenolic fibers for the first time. Epoxy-modified thermoplastic phenolic resin was first prepared in acidic condition using phenol, formaldehyde, and epichlorohydrin as the reactants, and then underwent additive reaction with formaldehyde to obtain epoxy-modified thermosetting phenolic resin, which was converted into nascent fibers through wet spinning. Finally, epoxy-modified phenolic fibers were obtained through different curing methods including solution cured, solution thermal cured, microwave cured, MTC, and was characterized by infrared spectroscopy, microscopic infrared imaging, nuclear magnetic resonance, thermogravimetric analysis, and scanning electron microscopy. The experiment results show that MTC epoxy-modified phenolic fibers have optimal mechanical property with ultimate elongation of 4% and breaking strength of 133 MPa. Graphical abstract
期刊介绍：
e-Polymers is a strictly peer-reviewed scientific journal. The aim of e-Polymers is to publish pure and applied polymer-science-related original research articles, reviews, and feature articles. It includes synthetic methodologies, characterization, and processing techniques for polymer materials. Reports on interdisciplinary polymer science and on applications of polymers in all areas are welcome.
The present Editors-in-Chief would like to thank the authors, the reviewers, the editorial staff, the advisory board, and the supporting organization that made e-Polymers a successful and sustainable scientific journal of the polymer community. The Editors of e-Polymers feel very much engaged to provide best publishing services at the highest possible level.
