A metal coordination crosslinking novel high performance thermoset Accession number: 20181104912224 Authors: Yang, Peng 1 ; Yang, Jun Xiao 1 ; Chang, Guan Jun 1 Author affiliation : 1 State Key Laboratory Cultivation Base for Nonmetal Composite and Functional Materials, School of Material Science and Engineering, Southwest University of Science and Technology, Mianyang; 621010, China Corresponding author: Chang, Guan Jun (gjchang@mail.ustc.edu.cn) Source title: Materials Science Forum Abbreviated source title: Mater. Sci. Forum Volume: 913 Part number: 1 of 1 Issue title: Functional and Functionally Structured Materials II - Chinese Materials Conference 2017, CMC 2017 Issue date: 2018 Publication Year: 2018 Pages: 746-751 Language: English ISSN: 02555476 CODEN: MSFOEP ISBN-13: 9783035712445 Document type: Conference article (CA) Conference name: Chinese Materials Conference, CMC 2017 Conference date: July 6, 2018 - July 12, 2018 Conference location: Yinchuan City, Ningxia, China Conference code: 211579 Sponsor: Chinese Materials Research Society (CMRS) Publisher: Trans Tech Publications Ltd Abstract: N-substituted crosslinking polybenzimidazole pyridine sulfone, as novel high performance functional polymers, was prepared by the coordination of N-substituted polybenzimidazole pyridine sulfone (Py-N-PBIS) ligand with varying content of metallic ion (Co2+, Ni2+, Zn2+). The structures of the polymers were characterized by means of FT-IR and1H NMR spectroscopy, and the results showed a good agreement with the proposed structures. TGA measurements exhibited that the crosslinking polymers possessed good thermal stability with high thermal decomposition temperatures (thermally stable up to 405-510 ¡ãC). Additionally, the thermal stability of the coordination polymers was improved constantly with the increasing of the content of Co2+, Ni2+or Zn2+. The metal coordination crosslinking N-substituted polybenzimidazole pyridine sulfone could be considered as a novel high performance thermoset. © 2018 Trans Tech Publications, Switzerland.
