Many kinds of hyper structured nano materials for industrial application are probably the class of materials with the widest variety of functionalities. Today the term hyper structured nano material encompasses a wide range of products such as displays, fuel storage, electronic devices and interconnect materials for semiconductor etc. In this study a review of the present status of the hyper structured nano materials will be given, together with a discussion of the major issues facing the industry. We have studied for many years about hyper structured nano materials like nano-porous P/F polymer particles, polycarbonate nano-particles and low dielectric constant materials using the advanced technology. Dispersed condensation polymerization is a novel process for the control of inner structure of polymeric materials, also, it can be utilized to synthesis of nano-structured porous particles. It was an object of the present proceeding to produce condensation polymers in the form of nano-sized particles by new process, which is capable of alternating the existing process, which requires very high temperature and vacuum to allow the removal of the condensate molecule from the polymer melt. Nano-sized porous polymer particles are applied to a nanofabrication for organic EL, enzyme, antibody, etc. We also prepared high molecular weight PC nano-particles using transesterification between bisphenol-A (BPA) and diphenyl carbonate (DPC) in supercritical CO2 which is an excellent plasticizing agent and a good solvent for phenol, by-product of the reaction. The porous thin film with a low dielectric constant for interlayer dielectric applications in microelectronics is essential that the layer maintain its specific electrical, physical, and chemical properties after incorporation in the device structure and during subsequent processing. |
