| titleOfInvention | A kind of LCP film for FPC industry and preparation method thereof |
| abstract | The present invention provides an LCP film used in the FPC industry and a preparation method thereof. The film is prepared from liquid crystal monomers as shown in formula I and formula II. The preparation method is as follows: pouring the liquid crystal monomers of the formula I and the formula II, the photoinitiator and the ultraviolet absorber into a liquid crystal cell, and at 95° C., under the ultraviolet light of 2mW/cm2 and 365nm to induce Polymerization, exposure for 30min, namely liquid crystal polymer. Dissolving the liquid crystal polymer in an organic solvent, adding polycarbonate resin, temperature-resistant Teflon resin and epoxy resin in turn, stirring and mixing evenly, transferring the obtained reaction solution into a twin-screw extruder for extrusion and granulation , and finally the dried particles are prepared into LCP films by a casting process. The LCP film has a low dielectric constant at high frequencies, which improves signal transmission speed and can be widely used in 5G networks. . |
