| Research Abstract |
Nanostructured conjugated polymeric materials are promising in various areas, and to establish a general synthetic process creating self-support hierarchical nanofibrillar polypyrrole materials is the purpose of the ongoing research.
So far, a facile chemical approach has been successfully developed to prepare hierarchical polypyrrole composite materials, by using natural cellulosic substance such as commercial filter paper as scaffolds.Nanoprecise coating of polypyrrole on virgin natural cellulose fibers as well as titania-coated cellulose fibers was achieved by means of a modified polymerization-induced, adsorption process.The polypyrrole coating was achieved at nanometer level, and hence the resulted polypyrrole composites posses the morphological hierarchies of the original cellulosic substances, for which unique functionalities can hence be expected.
Moreover, the current nanocoating approach also provides a way to control the surface physical properties of cellulosic substances, like the hydrophobicities.
The current demonstrated technique is of sufficient generality for various polymers and substrates, and opens up new doors for nanostructured materials of insoluble conjugated polymers.
