Title:
HETEROATOM DOPED POLYMER NANOSPHERE/CARBON NANOSPHERE AND PREPARATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/024766
Kind Code:
A1
Abstract:
Disclosed is a heteroatom doped polymer nanosphere/carbon nanosphere and a preparation method thereof. The method uses an aromatic amine and an aldehyde as raw materials and, in the presence of a compound represented by general formula (I) below, reacts the aldehyde with the compound represented by general formula I to form a Schiff base, and then reacts the aromatic amine with the resulting Schiff base, wherein the reaction is conducted in an aqueous solution system at a mild reaction temperature (10°C to 50°C) under stirring. The resulting polymer nanospheres are subjected to centrifugation and drying, followed by baking in an inert atmosphere to obtain carbon nanospheres. The preparation method of the present invention is simple, mild, and fast, allowing for production in large amounts. The nanosphere product prepared using the method has controllable dimensions and morphology, an even particle size, and homogeneously doped heteroatoms, and thus has good prospects for application.
