| 摘要 |
The disclosure relates to a reversible, electrically controllable light transmission (RECLT) film, article of manufacture composition, process and product produced by the process, comprising a conductive narrow composition distribution polyvinylidene fluoride copolymer in combination with an electrolyte and an RECLT material. The narrow composition distribution polyvinylidene fluoride copolymer has low solubility, high thermal stability and strength, and very high optical clarity. The polyvinylidene fluoride copolymer comprises a nonporous or porous copolymer of vinylidene fluoride preferably with either hexafluoropropylene or tetrafluoroethylene or chlorotrifluoroethylene, or vinyl acetate, or combinations thereof. The RECLT material includes organic or inorganic compounds known in the art. Typical RECLT materials include electrochromic materials, reversible metal electrodeposition materials, liquid crystal materials and dispersed particle materials.
