Statistically designed amphiphilic copolymer coatings were deposited on to Thermanox®, Si wafer and quartz crystal microbalance (QCM) substrates via Plasma Enhanced Chemical Vapor Deposition (PECVD) of 1H,1H,2H,2H-perfluorodecyl acrylate (PFDA) and diethylene glycol vinyl ether (DEGVE) in a Inductively Excited Low Pressure Plasma reactor. Plasma deposited amphiphilic coatings were characterized by Field Emission Scanning Electron Microscopy (FESEM), X-ray Photoelectron Spectroscopy (XPS), Atomic Force Microscopy (AFM) and Water Contact Angle (WCA) techniques. The surface energy of the coatings can be adjusted between 12 to 70 mJ/m2. The roughness of the coatings can be tailored de-pending on the plasma mode used. A very smooth coatings was deposited with a CW (continuous wave) power, whereas, a rougher surface with Ra in the range of 2 to 12 nm were deposited with the PW (pulsed wave) mode. The nanometer scale roughness of amphiphilic PFDA-co-DEGVE coatings was found to be in the range of the size of the two proteins namely BSA & Lysozyme used to examine for the antifouling properties of the surfaces. The results show that the statistically designed surfaces, presenting a surface energy around 25 mJ/m2, present no adhesion with respect to both proteins measured by QCM. |
