Abstract
A composition for encapsulation and an encapsulated apparatus, the composition including a (meth)acrylic alkoxysilane monomer including a moiety represented by Formula 1 or 2, below, or an oligomer thereof; a multifunctional (meth)acrylate monomer or an oligomer thereof; and an initiator, wherein * and ** represent a binding site between elements.
Claims18
A composition for encapsulation, comprising:
- greater than 10 wt % to about 85 wt % of a (meth)acrylic alkoxysilane monomer including a moiety represented by Formula 1 or 2, below, or an oligomer thereof;
- about 10 wt % to about 89 wt % of a multifunctional (meth)acrylate monomer or an oligomer thereof;
- and
- about 0.1 wt % to about 5 wt % of an initiator, all amounts being in terms of solid content in the composition for encapsulation,
- wherein * and ** represent a binding site between elements, and
- wherein the multifunctional (meth)acrylate monomer or oligomer thereof has a weight average molecular weight of about 50 g/mol to about 1,000 g/mol.
A composition for encapsulation having a curing shrinkage of about 10% or less, a storage modulus after curing of about 5 GPa to about 20 GPa, and an adhesive strength to an inorganic barrier layer after curing of about 20 kgf/(mm)2 to about 100 kgf/(mm)2, wherein the composition includes:
- greater than 10 wt % to about 85 wt % of a (meth)acrylic alkoxysilane monomer including a moiety represented by Formula 1 or 2, below, or an oligomer thereof, and
- about 10 wt % to about 89 wt % of a multifunctional (meth)acrylate monomer or an oligomer thereof, all amounts being in terms of solid content in the composition for encapsulation,
- wherein * and ** represent a binding site between elements, and
- wherein the multifunctional (meth)acrylate monomer or oligomer thereof has a weight average molecular weight of about 50 g/mol to about 1,000 g/mol.
