Abstract

The 2022 3rd International Conference on Material Chemistry and Composite Materials (MCCM 2022) took place via virtual form on December 16th-18th, 2022 in Zhuhai, China particularly favorable for informal and in-depth discussions. Invited and contributed papers present state-of-the-art research in material chemistry and composite materials. This workshop always welcomes a fruitful mix of experienced researchers and students, to allow a better understanding of related fields.The 2022 session of the material chemistry and composite materials, hosted by Guilin University of Technology, was doubtlessly a great success. The program encompassed a wide variety of topics, namely New Energy Materials, Polymer Material, Computational Materials Science, Molding Process of the Material, etc. All papers published in this volume of Journal of Physics: Conference Series (JPCS) have been peer reviewed through processes administered by the proceedings Editors. Reviews were conducted by expert referees to the professional and scientific standards expected of a proceedings journal published by IOP Publishing.About 150 delegates from around the world participated in the conference, and the conference agenda was divided into two sessions, including Keynote Speeches and Oral Presentations. Each keynote speaker was given 30-40 minutes for keynote speeches. Among them, Prof. Yang Liu from Huazhong University of Science and Technology, China performed a keynote speech on the title: New Molecular Insight into Ferroelectric Polymer and Nanocomposites. In this talk, he first presented their discovery of morphotropic phase boundary-like behavior in ferroelectric P(VDF-TrFE) copolymers which exhibits the state-of-the-art piezoelectric coefficient of - 63.5 pC/N. Moreover, he revealed the origin of relaxor behavior in ferroelectric polymers. Finally, he addressed recent emerging advance especially achieved by scanning probe microscopy which has been used to characterize the interface in terms of different polymer matrix, fillers and filler size. The insightful speeches of each keynote speakers triggered heated and interesting discussions and a good number of informal talks between all the participants and it was a great opportunity to promote academic communication and collaboration.List of Committee member is available in the pdf.
