Title of Talk

Green system for metals protection based on the use of silanes

 

Abstract

Traditional anticorrosion system usually uses environmentally unfriendly chemicals, such as chromate and phosphate compounds. To overcome this drawback and to meet the requirement of sustainable development in the modern society, green system consisting of eco-friendly components has attracted more and more interest in the past decade. In this talk, new painting systems developed in our research group which are based on the use of organosilanes and inorganic silica materials, i.e. sol-gel materials, will be presented. Such sol-gel materials can either be used as the pretreatment layers or effective additives for the primers. When used as the pretreatment layer, electrodeposition is recommended because this technique is capable of generating much thicker films. We believe that the new painting system using sol-gel materials as the pretreatment layers and corrosion inhibitors in primers is a promising alternative to the conventional painting system.

Profile. Prof Jiming Hu received his PhD in Materials Science and Engineering from University of Science and Technology Beijing (USTB) in 2000. He then worked in Zhejiang University (2000-2002) and Hong Kong University of Science and Technology (2002-2003) as the postdoctoral fellow. He joined Zhejiang University as an associate professor in 2003 and was promoted to full professor in 2007. Prof Hu has received numerous awards including the Chinese Chemical Society Prize for Young Scientists (2007), the Qianjiang River Talent of Zhejiang Province (2010), and the New Century Excellent Talents in University from Ministry of Education (2011).

His research interests lie in the general areas of Electrochemistry, Corrosion and Protection of metals, in particular in seeking green methodologies for metal protection. Prof. Hu has been recognized in the field of electrochemically assisted deposition of protective silane films and silane-incorporated super-primers. His recent research interests focus on the electrodeposition of inorganic silica films and concentrate on exploring new applications of such films in anticorrosion materials and protection systems.
