Abstract

The invention discloses amino-modified nano-polystyrene and a preparation method thereof, and belongs to the field of nano-material preparation. The amino-modified nano-polystyrene comprises, in weight percentage, 2-8% of monomer styrene, 0.5-1.5% of dodecyl amine-hydrochloride, 0.3-0.5% of 2, 2'-azobis [2-methylpropionamidine] dihydrochloride and the balance water. The amino-modified nano-polystyrene has the advantages of simple and convenient process, mild reaction conditions, simple reaction equipment, grain size controllability and green and environmental protection property.

Description

technical field [0001] The invention relates to the field of nanomaterial preparation, in particular to an amino-modified nano polystyrene and a preparation method thereof. Background technique [0002] Surface-functionalized polymer microspheres have received more and more attention. Such microspheres can be widely used in many fields, such as biochemistry and biomedicine, pharmaceuticals, chromatographic column packing and clinical testing. So far, researchers have prepared polymer microspheres with various functional groups, including carboxyl, hydroxyl, amino, vinyl, azo, etc. These surface-functionalized polymer microspheres can be used to immobilize and detect biomacromolecules such as proteins such as antibodies and enzymes. [0003] It is relatively easy to introduce amino groups on the surface of metal or semiconductor nanoparticles, so most of the current research is limited to the amination of metal or semiconductor nanoparticles, and there are relatively few stu...
