To improve organic surface for the application of hybrid materials is required the molecular bridge( as interaction) .Kusano Sensei knows my work due to the special support for our special book which has translated by Kusano Sensei. Then, I would like to introduce as follows:
For strengthening the bonding force with the polymer of the base material, a crosslinkable functional group must be added. In this field, we completed the basic technology for complex development using plasma, ultraviolet rays and special coupling agents more than 25 years ago. Many plasma personnel have not yet developed a comprehensive technology, so only wettability is targeted. However, plasma may have an adverse effect on strengthening bonding and preventing material deterioration.
Surface modification of materials is used in various technologies: preparation of asphalt pavement, preparation of concrete, new adsorbent materials, wastewater treatment .. For this, the surface is modified with various functional groups due to the creation of intermolecular or chemical bonds.
The final Surface of the organic pigments or dyes are converted to amorphous Silica nano thickness film completely.
To insulate toxic substances ,to remove hydrohobicity and to improve mechanical property , the organic functional groups in the surface layer are temporarily bonded by the organic silicate, and then the silicate forms a homogeneous film without cracking by gentle self-hydrolysis. By electron microscopic precision imaging of the interface, the relationship between the two is that a gradual interface exists with a film thickness of 1 nm or less.
