| titleOfInvention | A kind of PLA particle and preparation method thereof |
| abstract | The invention discloses a kind of PLA particle and preparation method thereof.It is to dissolve PLA and water-soluble polymer with solvent, forms it into the two phase emulsion of PLA solution phase and water-soluble polymer solution phase, at a temperature of 30 °C ~ 60 °C, adds precipitating reagent and obtains porous PLA particle；Wherein, the temperature of the precipitating reagent of addition is 0 °C ~ 10 °C.The inventive method operation facility, mild condition, by means of water-soluble polymer and precipitating reagent, it is possible to prepare cellular PLA particle, its oil absorption is in 400mL/100g ~ 600mL/100g, especially suitable for industrialized production.Particle can be widely applied to the fields such as cosmetics base material, catalytic adsorption, insoluble drug release, biological support. |
