The invention relates to a preparation method of a
carbon dioxide responded
graphene nano hybrid material, which comprises the following steps of reacting 5,10,15,20-tetrakis(4-aminophenyl)-21H,23H-porphine with 1,1-dimethoxy-N,N-dimethylethylamine so as to obtain 5,10,15,20-tetrakis(4-phenyl-N,N-dimethyl-N''-acetamidine
bicarbonate)-21H,23H-porphine; and then, adding
grapheme, so that molecules of the 5,10,15,20-tetrakis(4-phenyl-N,N-dimethyl-N''-acetamidine
bicarbonate)-21H,23H-porphine are coupled on the surface of the
grapheme, and then a
grapheme-5,10,15,20-tetrakis(4-phenyl-N,N-dimethyl-N''-acetamidine
bicarbonate)-21H,23H-porphine
nano hybrid material is formed. The grapheme
hybrid material prepared according to the invention has
carbon dioxide responsiveness, and the dispersion of the
hybrid material in an
aqueous solution can be reversibly regulated through feeding
carbon dioxide or
argon into the
aqueous solution, and therefore, the
hybrid material has wide applications in the fields of
drug controlled release carriers, intelligent switches, intelligent sensors, biological nano-devices and the like. The preparation method disclosed by the invention is simple and practicable, and raw materials can be subjected to industrialized production, and therefore, the preparation method has good popularization and application values.
