Ceramic and plastic composite

Abstract

A ceramic and plastic composite includes a ceramic matrix and a plastic layer. Plastics are injected onto the surface of the baked ceramic matrix to form a plastic layer. The plastic layer more deeply fills nanoholes distributed on the surface of the ceramic matrix 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.

What is claimed is: 
     
         1 . A ceramic and plastic composite comprising a ceramic matrix and a plastic layer formed by injecting plastics onto a surface of the ceramic matrix, characterized in that a plurality of nanoholes are distributed on the surface of the ceramic matrix, an average diameter of the plurality of nanoholes ranges between 150 nm and 450 nm, the plastic layer is embedded into the plurality of nanoholes, and a force of combining the plastic layer with the ceramic matrix reaches 300 kg/cm 2 . 
     
     
         2 . The ceramic and plastic composite according to  claim 1 , wherein the average diameter of the plurality of nanoholes ranges between 200 nm and 400 nm. 
     
     
         3 . The ceramic and plastic composite according to  claim 1 , wherein the ceramic matrix comprises Si 3 N 4 , WC, ZrO 2 , or Al 2 O 3 . 
     
     
         4 . The ceramic and plastic composite according to  claim 1 , wherein the plastic layer comprises polyamide (PA), polyphenylene sulfide (PPS), poly-(Butylene Terephthalate) (PBT), or polyetherketoneketone (PEAK).
