No template method for rapid synthesis of micro/nanoballs

China Coatings Network
: Recently, The Xu Guobao Task Force, a national key laboratory for electroanalytical analysis and chemistry of the Chinese Academy of Sciences, made new progress in micro/nano research. They first reported the use of simple templateless methods to synthesize highly average inter-aminophenol-formaldehyde resin polymer balls and carbon balls. On this basis, a simple and rapid synthesis of high-quality inter-aminophenol-formaldehyde resin encased trioxide nanoparticle composite ball method has been developed. Inter-aminophenol-formaldehyde resin has good thermal stability, after carbonization to obtain the corresponding carbon-pack iron oxide nanoparticle composite ball. The prepared magnetic composite nano-ball surface has a wealth of amino and other active groups, easy to further functionalize, to promote the application of magnetic nanomaterials has great significance.
it is understood that micro/nanospheres are widely used in analytical chemistry, drug transmission, biomedicine, collosal catalysis and photonic crystals. However, at present, the preparation of collage balls with uniform size, with the help of templates or surfactants and other synthesis methods, there are still complex routes and other disadvantages.
