This document discusses surface modification techniques. It introduces surface modification and lists some of its purposes like enhancing anticorrosive and adhesion properties. It presents a modern classification of surface modification and discusses some technical resources for surface modification like plasma treatment and corona discharge. Plasma treatment can be used for micro cleaning, functionalization, and establishing hydrophobic and hydrophilic properties. Corona discharge modifies surfaces to provide longer lifespan, improve bonding and corrosion resistance. It also lists some commercial corona plasma equipment manufacturers and provides references.

optical
properties.
 Produced biocompatibility

8. Surface modification technical
resources
 1. Plasma Treatment

9. Plasma Treatment
Plasma Treatment Helps To…
1. Micro clean to enhance the surface wetting of
adhesive.
2. Functionalize group to improve surface
energy.
3. Establish hydrophobic and hydrophilic
properties.

10. Plasma functionalization of organic
materials
oxygen plasma
Surface polymer
C-OH C-O COOH C=O
. Polar groups on a polymer surface cause a dramatic increase of
surface wettability.
Reactive particles from oxygen plasma are incorporated on the
surface forming O-rich functional groups.

11. Corona Discharge
It Modifies The Properties of A Surface To-
 Provide a longer lifespan.
 Improve surface bonding.
 Improve corrosion resistance.
