Over the past several years we have witnessed an exponential growth in the production of novel nanomaterials. The enormous demand for technological solutions by major manufacturing industries presents a strong driving force in the search for more advanced nanomaterials. Research and development efforts in the field seem to focus on the discovery of new physical and chemical properties among modern nanomaterials. One punctilious challenge is the need to make sure that these nanomaterials are environmentally friendly. Biocompatible polymer coatings can reduce the toxicity of nanoparticles , coating of silver nanoparticles with a biodegradable polymer can prevent toxicity , and carbon nanotubes can be coated by spontaneous oxidative polymerization of dopamine . One of my research interests is to coat silica, titania and other metal oxide nanoparticles with polydopamine. Photolytic generation of activated oxygen is being investigated to accelerate the oxidative polymerization. More possibilities will be derived from the spontaneous polymerization of aniline, thiophene, pyrrole and phenols.
This special issue aims to encourage worldwide researchers in sharing their scientific and technological knowledge on new polymer coatings of low toxicity and facile formation. It may include novel synthetic routes for coating nanomaterials with proper biocompatible polymers, strategies for rapid formation of thick polymeric films, and instrumental methods for characterization of their unique physicochemical properties. Special welcomes will be extended to emerging technologies that are best suited for coating a variety of nanomaterials and biocompatible polymers that can be applied in very large volumes of environmental water.
