Formulation of porous material from xyloglucan and polyvinyl alcohol, and manufacturing process.

Abstract

The formula for preparing porous materials from xyloglucan and polyvinyl alcohol consists of xyloglucan. Polyvinyl alcohol, citric acid, distilled water, or deionized water are used in the following process: Prepare a polyvinyl alcohol solution by dissolving it in distilled or deionized water using an ultrasonic device. The sonic homogenizer is heated, and xyloglucan is added to the polyvinyl alcohol solution. The mixture is then stirred. Using an ultrasonic homogenizer, heat the solution, add citric acid, and mix. Using an ultrasonic homogenizer, pour the mixture into a container of the desired shape, freeze it, and then put it into the machine. Freeze-drying: Place the dried workpiece on a Teflon tray and put it in a convection oven. Remove the perforated material. The prune hydrogel is removed from the oven.
