Abstract

Recently, displays and optoelectronics have made remarkable development because they are the most frequently exposed applications to humanity. The pixel size has become smaller and a new form factor is needed for displays and optoelectronics beyond rigid ones. New material breakthroughs enabling new form factors with plastic-like flexibility, mechanical toughness as well as glass-like thermal/mechanical resistance and low thermal expansion are required. Sol–gel-derived siloxane hybrid material (Hybrimer), showing synergetic properties of organic and inorganic (O–I) materials, can be realized by chemical hybridization and dense O–I co-networks. In addition, the characteristics of hybrimer can be easily optimized via control of organic functional groups, sol–gel reaction, and polymerization steps. First, a sol–gel reaction and polymerization, which enables chemical hybridization of O–I groups, are introduced. Then, the various display and optoelectronic applications using hybrimer achieved by control of properties are provided: (i) patterning, (ii) passivation, (iii) glass-fabric reinforced film, and (iv) color conversion films. This paper includes a brief overview of fabrication process and applications using hybrimer developed over the past decades.

Highlights

  • Sol–gel-derived siloxane hybrid material (hybrimer) is composed of a chemical hybridization between organic and siloxane phase.

  • Hybrimer can be simply fabricated using sol–gel reaction and polymerization.

  • Properties of hybrimer can be easily tuned by controlling the organic groups and sol–gel reaction.

  • Hybrimer can be applied to various display and optoelectronics.
