Abstract:

The proposal was directed towards the fundamental understanding of two areas of polymer materials 1 Phase Transformations and Microstructure, 2 Ultrastructure and Mechanical Properties. Years 1 and 2 were primarily concerned with rigid rod PBX-type materials. During Year 2 and especially in Year 3 emphasis was redirected toward technique development AFM and LVHRSEM for materials characterization, and materials processing roll casting of block copolymers and magnetic field alignment of liquid crystalline polymers. As well, efforts shifted to block copolymer materials during the second half of the grant. Collaborative efforts with Professor P. Prasad at the University of Buffalo sol-gel composites and Professors S. Gruner and P. Chaikin at Princeton University phase transitions and nanolithographic uses of block copolymers were quite successful
