  • Patent number: 10934455
    Abstract: The present invention relates to a polysilsesquioxane resin composition for a flexible substrate. More specifically, the present invention relates to a polysilsesquioxane resin composition for a flexible substrate, having excellent heat resistance and transparency, the resin composition being usable for a flexible display substrate. More specifically, a transparent thin film can be formed, excellent transmittance is exhibited in the visible range even after curing, heat resistance is excellent, and flexibility and crack resistance can be controlled. Compared to a conventional polyimide-based substrate material, the present invention has excellent insulation characteristics and passivation characteristics, which can be satisfied simultaneously, and is advantageous for productivity since release characteristics are ensured during a delamination process from a glass substrate.

  • Patent number: 10843445
    Abstract: A sheet-shaped matched-type electromagnetic wave absorber can obtain electromagnetic wave absorption performance with a relatively small thickness but has a problem that particularly a dimensional change in an electromagnetic wave absorption layer (resin composition layer) has a large influence on the electromagnetic wave absorption performance when being exposed to a high temperature. By laminating a resin composition layer in which a filler with an aspect ratio of 5 or more and a filler with an aspect ratio of less than 5 are dispersed and fixed with an electromagnetic wave reflection layer in a cured product of a resin composition containing an acrylic polymerizable resin and a polymerization initiator, it is possible to provide a matched-type electromagnetic wave absorber having high heat resistant dimensional stability and high electromagnetic wave absorption performance.
