| titleOfInvention | Temperature-pH dual-sensitivity gel microsphere as well as preparation method and application thereof |
| abstract | The invention provides a gel microsphere product having temperature-pH dual-sensitivity. The average pore size of the gel microsphere is in a range of nanometers to 200 nm and the average grain size thereof is 1-100 microns. The preparation method comprises the following steps of: (1) providing an aqueous solution which is dissolved with water-soluble monomer N-isopropyl acrylamide, acrylic acid, an initiator and a cross-linking agent as an aqueous phase W; (2) providing oily substance which is dissolved with an oil soluble emulsifying agent and is insoluble with water as an oil phase O; (3) mixing the aqueous phase with the oil phase to obtain a W/O emulsion, agitating and introducing an inert gas; (4) keeping the inert gas atmosphere, adding an accelerant into the W/O emulsion, and polymerizing to obtain the gel microsphere at a temperature which is lower than the critical dissolving temperature of N-isopropyl acrylamide; and (5) washing the polymerized gel microsphere to obtain the gel microsphere product. The invention further provides application of the gel microsphere. |
