23 Jul Sulfonated poly N-phenylglycine photo-thermal material as well as preparation method and application thereof
Abstract
The invention discloses a sulfonated poly N-phenylglycine photo-thermal material as well as a preparation method and an application thereof. The preparation method comprises: carrying out oxidation polymerization on an N-phenylglycine monomer by using ammonium persulfate to obtain poly N-phenylglycine; and carrying out chlorosulfonic acid sulfonation to introduce a sulfonic group into an aromatic ring structure of the poly N-phenylglycine so as to obtain a water-soluble photo-thermal material namely sulfonated poly N-phenylglycine. The synthetic method is available in raw materials, and is simple in synthesis process and small in environmental protection; meanwhile, the carboxyl on the sulfonated poly N-phenylglycine can be subjected to modification to obtain an efficient high polymer photo-thermal material with multiple functions, and the efficient high polymer photo-thermal material has an application value in treatment of cancer; and the kill rate of cancer cells is enhanced by using photo-thermal treatment of the N-phenylglycine photo-thermal material, so that the N-phenylglycine photo-thermal material has an extensive application prospect in the aspects of photo-thermal treatment, functional materials, tissue engineering and the like.
