Then after a certain treatment, it is made into colloid.
Dry it again, then take some out and add it to a special liquid (acid, etc. )
Then add the substance to be synthesized with it and stir it with a blender.
And then dry to prepare that composite material.
A few days ago, I saw a patent: the invention discloses a method for preparing a composite material of carboxymethyl cellulose and bacterial cellulose, which includes the following steps: making naturally fermented coconut water, distilled water, ammonium sulfate, magnesium sulfate, disodium hydrogen phosphate and sucrose into a culture medium, then adding carboxymethyl cellulose, adjusting the pH value of the culture medium to 3.9-4.2, then sterilizing at high temperature and high pressure, and inoculating liquid seeds of Acetobacter xylinum into the culture medium after the culture medium is cooled to room temperature. The wet film of carboxymethyl cellulose and bacterial cellulose composite was obtained by static culture, and the dry film of carboxymethyl cellulose and bacterial cellulose composite was obtained by freeze-drying after the wet film was purified and stored for later use.
