Abstract

A composite includes a substrate having an oxide layer, a nano film formed on the oxide layer, a plastic member, the nano film has a three-dimensional network structure, the plastic member covers the nano film and penetrates into the three-dimensional network structure, the plastic member bonds with the substrate through the nano film and the oxide layer.

First claim

What is claimed is:

1. A composite comprising:
a substrate;
an ink layer formed on the substrate;
a nano film formed on the ink layer, the nano film having a three-dimensional network structure and a thickness of between about 3 nm to about 15 nm; and
a plastic member covering the nano film and penetrating into the three-dimensional network structure, the plastic member bonding with the substrate through the nano film and the ink layer.

2. The composite as claimed in claim 1 , wherein the nano film is a product of a polycondensation reaction between OH groups contained in resultant hydrolytic reaction products of alkaline organic silanes reacting with water, the nano film has Si—O—Si groups and alkyls.

3. The composite as claimed in claim 2 , wherein the ink layer contains alkyls, the alkyls of the ink layer and the alkyls of the nano film have the same or similar structure, such that the ink layer bonds with the nano film.

4. The composite as claimed in claim 1 , wherein the ink layer has a thickness of between about 15 μm to about 25 μm, and is made of an epoxy resin, a polyamide resin or an acrylic resin.
