With its unique chemical structure and physical properties, this material provides an environmentally friendly and durable alternative, especially today when traditional animal leather and synthetic leather face environmental and ethical challenges. The application range of silicone film is very wide, from car interiors, furniture decoration, electronic product exteriors, and outdoor equipment. With the advancement of technology and the increasing demand of consumers for environmentally friendly materials, silicone film is gradually becoming a popular choice in the market.

[0003] In the prior art, although there is no shortage of products made of silicone in the above-mentioned fields, such products usually only have a single silicone rubber property and do not have the ability to emit light according to environmental conditions. Summary of the invention

In some embodiments, the adhesive layer can be an OCA adhesive coating, an acrylic adhesive coating, or a silicone coating, etc.

[0055] In some embodiments, the first functional layer 10 may be added with a luminescent material. In this case, by adding the luminescent material to the first functional layer 10, the first functional layer 10 can also have a luminescent effect, thereby further improving the luminescent effect of the luminescent silicone article 1.

[0056] In some embodiments, the luminescent material can be one of fluorescent powder, luminous powder, reflective powder, temperature-change powder, pearl powder, light-changing powder, and phosphorescent powder.
