Since most of recent advances in science and technology may have not been achieved without polymer and polymer technology, some have called this the “polymer age”. Polymers have inherent characteristics such as high molecular weight, polydispersity, diversity of chemical structure, chain-like molecular shape, anisotropy and viscoelasticity. Accordingly, as compared to metals and ceramics, polymers have unique properties: low density, easy to process, easy to manufacture highly complex parts, excellent thermal insulation, diverse electrical properties from excellent insulation to high electrical conductivity, and wide range of strengths, flexibility and degree of toughness depending upon the chemical and physical structure. In this talk, various aspects of polymers and polymer technology will be discussed on the basis of my research experiences for the past 36 years in Seoul National University: synthesis, structure, properties and applications of polymers (e.g., copolymerization to create new polymer; polymer blends (e.g., the use of block copolymer as compatibilizer to reduce the domain size and to increase interfacial adhesion in polymer blend); theory and simulation of polymers and multiphase polymers (e.g., theoretical derivation of EOS to predict the phase behavior of polymer blend, molecular simulation of polyimides to predict their mechanical properties, computer simulation to predict self-assembly and microphase separation of ring block copolymer, theory and experiment of block copoplymer-like supramolecule, molecular simulation to predict the crystal structure of new polymer); biopolymers and sensors (new type of pH sensor using FRET, computer simulation of ClC channel); nanocomposites (dispersion of CNT in polymer matrix using a new polymeric surfactant); polymer-based solar cells (molecular design and synthesis of new semiconducting polymers, development of new hole transport layer material, stability and durability). |
