| titleOfInvention | A kind of preparation method of polylactic acid material with anti-adhesion and sterilization function |
| abstract | The present invention prepares a polylactic acid material with anti-adhesion and sterilization function. The steps are: 1) stirring and dissolving the biodegradable material polylactic acid in a good solvent, adding a poor solvent to achieve phase separation, and fully stirring to obtain a coating solution 2) The solution obtained in 1 was uniformly coated on the PLA sheet and dried; 3) The top layer PLA was peeled off with tape to obtain a superhydrophobic surface; 4) The chlorophyll was dispersed in absolute ethanol and applied to the PLA sheet Superhydrophobic surface, dry. The surface of the material not only possesses superhydrophobic properties to resist the initial adhesion of bacteria, but also photodynamically kills the adhered bacteria. Super-hydrophobic and photodynamic synergistic antibacterial method, less bactericide dosage, high bactericidal efficiency, good antibacterial long-term effect, strong controllability, and will not induce bacterial resistance. The polylactic acid material with anti-adhesion and sterilization function prepared by the invention is non-toxic and harmless, has good biological and environmental compatibility, and can be used for medical or packaging materials to resist bacterial infection. |
