报告人简介：
Richard J. Spontak achieved the Ph.D. from University of California at Berkeley at 1988, then he was a research scientist with Procter & Gamble before he joined the North Carolina State University (NCSU) faculty in 1992. As a Distinguished professor of NCSU, Prof. Spontak conducts studies to improve the current understanding of microstructural polymer systems, which are of scientific interest as self-assembling polymers and commercial value as adhesives, (bio) compatibilizing agents, nanotemplates, and membranes. His group’s efforts are at the cutting edge of block copolymer research: e.g., they have obtained the first 3D images of the bicontinuous gyroid (Ia3d) and sponge (L3) morphologies. They characterize polymers with electronspectroscopic microscopy, and dispersions/gels with freeze-fracture replication and cryo-TEM techniques. Use of these tools has expedited the study of block copolymers and their blends/gels, and has helped to elucidate novel polymer gelation mechanisms, PDLC composition/morphology relationships, and interpolymer complexation. Other areas of interest include polymer alloying through mechanical attrition, transmission electron microtemography, and modification of polymer solutions via salting-in. He has over 300 publications in Advanced Materials, Advanced Functional Materials, Nature Communications, Macromolecules, ACS Applied Materials & Interfaces and other peer-reviewed journals, his work has been featured on the cover of Microsc. Res. Tech., Langmuir and so on.
