Abstract

The invention discloses a preparation method of a thermo-sensitive fluorescent polymer. The preparation method comprises the following steps: (1) synthesizing an NMA (N-alpha-naphthyl methacrylamide) monomer; (2) synthesizing a P(St-co-NMA)m (poly(styrene-co-NMA) macromolecular chain transfer agent; (3) synthesizing P(St-co-NMA)m-b-PENGMAn (P(St-co-NMA)m-b-poly(polyethylene glycol methacrylate)), namely the thermo-sensitive fluorescent polymer. According to the preparation method, the prepared nanoparticles simultaneously have thermosensitivity and fluorescence, and a series of fluorescent nanoparticles with different particle sizes can be prepared by changing external conditions.

Description

technical field

[0001] The invention specifically relates to a preparation method of a temperature-sensitive fluorescent polymer. Background technique

[0002] Environmentally responsive functional polymers have become a research hotspot in recent years. When the external environment (such as light, temperature, pH, ionic strength, electric field and magnetic field, etc.) changes, some physical or chemical properties of the polymer (morphology, Size, catalysis, recognition, etc.) will undergo corresponding reversible or irreversible changes, and has potential application value in the fields of controlled drug release, separation, microelectronics, optics, and catalysis.

[0003] At present, the emulsion polymerization method is a mainstream method for preparing functional polymer nanospheres. By adjusting the amount of initiator, monomer amount, temperature, pH, stirring intensity, emulsifier type and amount, etc., different particle sizes and monodisperse particles can be p...
