| 摘要 |
<p>The present invention relates to a modified organic-inorganic hybrid copolymer capable of being used to improve heat resistance, chemical resistance, light transmittance, and hardness of a polymer plastic substrate material which can be, for example, used in a flexible display. The present invention also relates to a method for preparing an organic-inorganic hybrid copolymer, a coating composition including the copolymer, a coating plastic substrate which can be obtained by using the coating composition, and a manufacturing method thereof. The organic-inorganic hybrid copolymer synthesized by using the method of the present invention includes a C-C bond, a Si-C bond, and an Si-O group. The coating film including a cured product of the organic-inorganic hybrid copolymer enables a conventional organic polymer plastic film to have heat resistance, chemical resistance, high light transmittance, and high hardness.</p> |
