Richard J. Spontak was a research scientist with Procter & Gamble before he joined the NCSU faculty in 1992. Spontak has over 104 publications in peer-reviewed journals, and his work has been featured on the cover of Microsc. Res. Tech. and Langmuir.
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.
