23 Jul Preparation method of copper metal organic frameworks / polyvinyl alcohol nanocomposite films
Abstract
The invention discloses a preparation method of copper metal organic frameworks / polyvinyl alcohol nanocomposite films. The method comprises the steps of S1, using triethylamine combining Cu3 (NO) 2 and trimesic acid as the material, adding the material in the mixture of deionized water and ethanol, stirring uniformly the mixture to obtain Cu3(BTC)2 nanoparticles, S2, adding polyvinyl alcohol into the deionized water, heating and stirring the water to obtain a polyvinyl alcohol solution, adding Cu3(BTC)2 nanoparticles into the polyvinyl alcohol solution, stirring the solution, conducting ultrasonic treatment to obtain Cu3(BTC)2/polyvinyl alcohol solution mixture solution, S3, pouring the mixture solution uniformly on a glass board, conducting vacuum drying to obtain the copper metal organic frameworks / polyvinyl alcohol nanocomposite films. The Cu3(BTC)2/polyvinyl alcohol nanocomposite film has a good mechanical strength, and has application potentials in the fields such as packing material, tissue engineering material and filtering film material.
