Abstract
A ceramic and plastic composite and a method for fabricating the same are disclosed. A chemical cleaning treatment, a microetching treatment, a hole reaming treatment, and a surface activating treatment are performed on the surface of a ceramic matrix to form nanoholes with an average diameter ranging between 150 nm and 450 nm. Plastics are injected onto the surface of the baked ceramic matrix to form a plastic layer. The plastic layer more deeply fills the nanoholes to have higher adhesion. Thus, the higher combined strength and air tightness exist between the ceramic matrix and the plastic layer to improve the reliability and the using performance of the ceramic and plastic composite.
