I want to form composite of pvdf with ceramic compound to dissolve pvdf I am using NMP, how will I dissolve ceramic.
In order to obtain a composite of (Lithium zirconium phosphate) in PVDF matrix, there is NO need to dissolve the (Lithium zirconium phosphate). The general steps for such process are:
1- Make a solution of the PVDF in a suitable solvent.
2- Add the ceramic powder with mixing and, if necessary, ultrasonic treatment. Sometimes, adding a surfactant is required to obtain a stable suspension.
3- Remove the solvent by normal evaporation, spray drying, or adding another liquid that can NOT dissolve the PVDF and has high affinity to the solvent.
Ultrasonic treatment is the best approach. Please find herewith a relevant paper.
To prepare a nanocomposite, no need to dissolve the phase (ceramic oxide) but you have to make a dispersion of your matrix materials (polymer). Then, add your phase to the dispersion and agitate by stirring or ultra-sonication and remove the solvent and excessive matrix materials to get the desired composite.
