Surface tailoring of an ethylene propylene diene elastomeric terpolymer via plasma‐polymerized coating of tetramethyldisiloxane

摘要: In the research presented here, we explore use of a low-energy plasma to deposit thin silicone polymer films using tetramethyldisiloxane (TMDSO) (H(CH3)2SiOSi(CH3)2H) on surface an ethylene propylene diene elastomeric terpolymer (EPDM) in order enhance hydrophobicity, lower energy and improve degradation/wear characteristics. The processing conditions were varied over wide range treatment times discharge powers control physical characteristics, thickness, morphology chemical structure films. Scanning electron microscopy (SEM) shows that pore-free homogeneous granular microstructure composed small grains are formed depends conditions, such as power time deposition. thicknesses coatings determined SEM, which confirmed deposited plasma-polymer could be precisely controlled by parameters. kinetics film deposition also evaluated. Contact angle measurements different solvent droplets used calculate energies coatings. These appeared hydrophobic had low energies. X-ray photoelectron spectroscopy (XPS) photoacoustic Fourier-transform infrared (PA-FT-IR) investigate detailed structures optimum achieve desired discussed light chemistry takes place at interfaces.
