One question you need to determine is how good of a dispersion do you really need (how well dispersed do you absolutely need?) This will determine how fine a particle you need to grind the PTFE (at very low temperatures). Then with both dispersions mixed as well as you can, you apply pressure and heat to the PTFE to sinter/fuse the PTFE particles to each other holding the titanium oxide particles in suspension.
Dear Andrew thanks for your qucik reply. I have titanium dioxidein powder form of 25 nanometer size anatase type particle. I would like to prepare emulsion of TiO2 and PTFE. PTFE is availble in solution form. What chemicals addition will provide better dispersion in PTFE. The PTFE and TiO2 emuldion will be used for surface coating. Kindly provide me the chemicals and their usage and procedure to prepare this emulsion. Thanks
