Xingfa Ma received his bachelor’s degree in Chemistry, specializing in polymers (now the Department of Polymer Science and Engineering), from Zhejiang University in 1987; his MD in Materials Engineering (polymer and its composites) from Harbin Institute of Technology in 2001; and his PhD in Materials Physics and Chemistry (now the Department of Polymer Science and Engineering) from Zhejiang University in 2005. He worked as a researcher of polymer applications at the Shandong Research Institute of Non-Metallic Materials (1987 to 2007). In 2007, he moved to Yantai University, and he was promoted to Professor of Materials Physics and Chemistry at the School of Environmental and Material Engineering in 2011. His research topics mainly include multifunctional organic/inorganic nanocomposites and their properties under visible light and NIR light (such as 405, 532, 650, 780, 808, 980, 1064 nm, etc.). Orcid: 0000-0003-2681-6158.  The focus of study is as follows. (1) The interfacial interaction of components in the nanocomposite promotes the separation and transfer of photogenerated carriers. (2) Defects tailoring of nanocomposites exhibited photoconductive signals in broadband spectrum range. (3) The defect passivation of the nanocomposites suppressed the photogenerated carrier recombination. Keywords: organic/inorganic functional nanocomposite; interface interaction; photoconductivity; broadband spectrum; defect tailoring.
