Curable composition, cured product, and methods thereof

A cured product comprising a curable composition, wherein the curable composition comprises:

• a polymer having a terminal unit;
• a monomer polymerizable with the terminal unit of the polymer;
• and
• an inorganic particle capable of absorbing moisture, wherein
• the inorganic particle comprises magnesium oxide surface-functionalized with a silane compound, and
• the silane compound comprises octadecyl (trimethoxy)silane (TODS), triethoxy(octyl) silane (TOS), or 3-(trimethoxysilyl) propylmethacrylate (TSMA).

A method, comprising:

• dispersing an inorganic particle in a monomer to form a first mixture;
• and
• mixing the first mixture and a polymer to form a second mixture, wherein
• the monomer is polymerizable with a terminal unit of the polymer, and
• the inorganic particle is capable of absorbing moisture,
• the inorganic particle comprises magnesium oxide surface-functionalized with a silane compound, and
• the silane compound comprises octadecyl (trimethoxy)silane (TODS), triethoxy(octyl) silane (TOS), or 3-(trimethoxysilyl) propylmethacrylate (TSMA).
