| titleOfInvention | Organic-inorganic double shell microcapsule for hydrophobic small molecules temperature control release and preparation method thereof |
| abstract | The present invention relates to organic-inorganic double shell microcapsule discharged for hydrophobic small molecules temperature control and preparation method thereof.At present, the also rarely seen open report of research of microcapsules is prepared using chitosan and silica as double-deck wall material.Amphiphilic triblock copolymer, silica precursor, silane coupler and hydrophobic small molecules material are added in organic solvent by the present invention simultaneously, and stirring and dissolving obtains mixed liquor at room temperature；90~150mg Chitosan powders are added in weak acid solution and obtain shitosan lysate；At room temperature, mixed liquor is gradually added drop-wise in shitosan lysate, ultrasound obtains the organic-inorganic double shell microcapsule for hydrophobic small molecules temperature control release.The present invention passes through interfacial polymerization, obtain using double-deck wall material microcapsules of the chitosan as shell, silica for inner casing, Release of core material rate gradually reduces with the rise of temperature, and this microcapsules not only have obvious temperature control releasability to hydrophobic small molecules, and its sustained release efficiency is higher. |
