THEORETICAL PREDICTION OF 3-DIMENSIONALLY CONJUGATED NOVEL POLYMERS WITH EXCELLENT MECHANICAL AND ELECTRIC PROPERTIES - STIFFER THAN DIAMOND

Is there no more possibility to produce a novel material with elastic modulus higher than diamond, starting from conventional synthetic poly mers? Through the computer-aided molecular design, a simple method of introduction of three-dimensional cross Linking into a conventional po lymer crystal lattice has been found to give three-dimensionally conju gated honeycomb-like structure, which has a tremendously high Young's modulus of 700-1800 GPa. This value is remarkably higher than that of diamond crystal, 1050 GPa. Thus constructed structure of isotropically conjugated system has additional possibility to give the highly elect rically-conductive polymer materials in three-dimensional directions.
