Abstract
A new method named polymer plating was developed for surface modification of stainless steel plates with different functional groups of organic solutions.The polymer-plated films on the surface of stainless steel plates were characterized by Fourier transform infrared spectra,contact angle and surface free energy.Compared with untreated stainless steel plate,the surface polymer-plated by TTN possessed hydrophilic characteristic with higher surface free energy and lower contact angle of distilled water,however,the polymer-plated films by DHN and AF17N had hydrophobic feature with lower surface free energy and higher contact angle of distilled water,where AF17N polymer-plated surface obtained optimal hydrophobicity because of the lowest surface free energy and the highest contact angles.This technique achieved the hydrophilic/hydrophobic modification on surface of stainless steel,and provided a method for fabricating polymeric function film with different wettability.
