| 제목 | Fabrication of polymer nanomaterials and their applications |
| 초록 | The development of novel fabrication routes for polymer nanomaterials is of special interest in contemporary materials science. The ability to generate nanometer-sized polymer materials can offer unprecedented and interesting insights into the physical and chemical properties differently with their corresponding bulk materials. In this presentation, we provide a diverse range of synthetic methods for fabricating polymer nanomaterials, which is significantly advanced by our group in these recent years. The diverse polymeric materials including vinyl polymer, thermoset polymer, conducting polymer and their derivatives were adopted to prepare polymeric nanomaterials using soft-template, hard-template, seed polymerization, interfacial polymerization and vapor deposition polymerization method. From the carbonization process (in the case of carbon precursor), the corresponding carbon nanomaterials could be obtained with maintaining their original shape. In addition, control of shape and structure of polymer nanomaterials affords versatile morphological spectrum such as nanoparticle, core-shell nanomaterial, hollow nanosphere, nanofiber/nanorod, nanotube, thin film and nanopattern and nanocomposite. Surface modification of polymeric or carbon nanomaterials has been attained great attention in recent years to make the nanomaterials more useful. We have the diverse techniques to control the surface of nanomaterials, including silane treatment, plasma modification, grafting polymerization, and vapor deposition polymerization. Functional thin layer could be introduced onto the prepared or commercialized nanomaterials without deformation of their original shape or properties. These methodologies provided novel approaches to prepare functional polymeric nanomaterials. In addition, their applications are discussed under nanometer-sized dimension as following: 1) The conducting polymer nanomaterials enable to prepare highly efficient chemical and biological sensor, 2) When the polymeric materials having biocidal effect are prepared in nanodimension, their antibiotic effect is largely improved due to their large surface area, 3) The nanomaterials also exhibit improved performance in the fluidic application such as nanofluid and electrorheological fluid, 4) We can prepare effective catalytic support with functional polymer nanomaterials having magnetic properties, 5) The micro-patterns composed of conducting polymer nanomaterials can be obtained by inkjet printing and this method proposes the possibility to totally organic electro-device, and 6) Miscellaneous.. |
