The oxidizable compound includes wherein each R2 is independently —N(R1)2, —OR1, or —R1, and R1 is C1-3 alkyl group. The reducible compound has a chemical structure of and each R3 is independently C4-12 alkyl group, —OCnH2n+1, and n=0˜7.

Abstract: A coating material includes a modified particle and a reactive compound. The modified particle includes a core, and a silane coupling agent having an epoxy group (or a double-bond) grafted onto a surface of the core. When the silane coupling agent having the epoxy group is grafted onto the surface of the core, the reactive compound includes a non-silicon multi-epoxy compound and a silicon-containing multi-epoxy compound. When the silane coupling agent having the double-bond is grafted onto the surface of the core, the reactive compound includes a multi double-bond compound.

Abstract: An electrochromic composition, an electrochromic layer and an electrochromic device are provided. The electrochromic composition includes 20-80 parts by weight of polyimide, 20-80 parts by weight of silicon oxide nanoparticle, 1-50 parts by weight of electrochromic material, and 850 to 1200 parts by weight of solvent. The polyimide is a reaction product of a dianhydride and a diamine. The dianhydride and the diamine are as defined in the specification.

Abstract: A composite material includes a core particle and a silane coupling agent including a double-bond or an epoxy group grafted onto the surface of the core particle. The core particle includes an oxide of zinc and titanium, and zinc and titanium have a weight ratio of 1:0.4 to 1:0.9. The composite material may react with a radical initiator or a crosslinker to form a film, and the film can be used to cover a light-emitting element of a light-emitting device.
