 劳伦斯·德·哈恩（Laurens Theobald de Haan）

Email: ldhaan@m.scnu.edu.cn

男，荷兰籍，华南师范大学全职教授。2014年11月博士毕业于荷兰埃因霍温理工大学功能有机材料与器件实验室，师从世界著名液晶高分子材料专家、荷兰皇家科学院院士 Dirk Jan Broer 教授。2015年7月于华南师范大学-深圳市国华光电科技有限公司博士后联合培养基地入站，参与荷兰埃因霍温理工大学、华南师范大学、深圳市国华光电科技有限公司共建的“红外反射液晶高分子材料与器件国际合作基地”的建设和合作研究工作。2018年作为特聘副研究员入职华南师范大学，2019年入选国家级人才项目并任全职教授。他目前的项目主要是开发基于液晶聚合物的响应表面材料，目前已在制备会因热、水和应变而改变颜色、或施加电场影响形状的光子表面新材料等方面取得一系列的重要成果和进展。劳伦斯·德·哈恩教授目前与埃因霍温理工大学有合作交流项目。

Prof. Laurens Theobald de Haan received his PhD degree in 2014 from the Eindhoven University of Technology on “Programmed Morphing of Liquid Crystal Polymer Networks”. His PhD supervisors were prof. D.J. Broer and prof. A.P.H.J. Schenning, who are both renowned professors in the field of liquid crystal polymer materials. After obtaining his PhD degree he accepted a postdoctoral position at South China Normal University (SCNU) in Guangzhou in collaboration with Guohua Optoelectronics in Shenzhen, under supervision of prof. G. Zhou. In 2019 he was awarded a national talents program and obtained his current position as a full professor at SCNU. His current projects mainly focus on the development of responsive photonic surfaces based on liquid crystal polymers. He and his students have prepared photonic surfaces that their reflective properties in response to heat, water, strain, and pH changes, and potential applications as sensors and in temperature-regulating smart windows have been demonstrated. In current and future projects, the responsiveness of the photonic polymers is further improved to expand the scope of these materials, for example to detect specific biomolecules or pollutants. Prof. Laurens de Haan has collaborations with professors at universities in the Netherlands and Belgium.
