Preface

Thanks to Prof. Tien-Chien Jen, the Chair Professor at Anhui Agriculture University and the Director of UJ-Nanjing Tech Joint Research Center in China, for assisting Modern International Green Cultural Communication Association (MIGCCA) to successfully hold the 2021 International Conference on Polymeric, Metallic and Composite Materials (PMCM 2021) during May 29-30, 2021 in Wuhan, China In light of the worldwide outbreak of COVID-19, there were only 20 people present at the meeting. In such a small academic conference, all participants have more opportunities to communicate and build relationships with other scholars. At the meeting, Prof. Abd El-Fatah Abomohra, as the keynote speaker, made a speech to discuss the potential uses of microalgae in human health, wastewater treatment and biofuels. Dr. Kinjal J. Shah, who was not available to attend the conference in China, sent us a prerecorded talk, which made the form of participation more diversified. Meanwhile, we highly encouraged doctorate (PhD) and postgraduate students to present their research proposal and findings in this conference. With the concerted efforts of us all, the conference has been a complete success and contributed significantly to promoting dialogue and exchanges among scholars and researchers to report most recent innovations and developments, summarize state-of-the-art, and exchange ideas and advances in the aspects of polymeric, metallic and composite materials.
