| titleOfInvention | Acrylic acid and polyhedral silsesquioxane copolymerized hydrogel, its preparation method and its purpose |
| abstract | The invention relates to a acrylic acid and polyhedral silsesquioxane copolymerized hydrogel, its preparation method and its purpose, which belongs to the intelligent high-molecular material technical field. According to the invention, a free radical solution polymerization method is used, and a polymer network structure is formed through the chemical crosslinking effect. The polymer possesses pHsensitivity group, and is capable of generating volumetric expansion or shrinkage by changing the environment pH value of environment. The hydrogel of the present invention is taken as a carrier of medicament slow release, the added POSS with minute quantity is capable of obviously reducing the release rate of the medicament coated in the hydrogel, medicament release time can be prolonged simultaneously, the PAA hydrogel possesses good biological compatibility, so that the prepared copolymerized hydrogel possesses potential value on being as the carrier aspect of the slow release medicaments. |
