Polyethylene glycol (PEG) is a key molecule in the fabrication of non-biofouling surface for various biological applications such as biochips and tissue engineering. In particular, plasma-polymerized PEG (PP-PEG) thin films have many practical uses due to their strong adhesion onto any solid substrates. In this work, we fabricate PP-PEG thin films by using the capacitively coupled plasma chemical vapor deposition (CCP-CVD) method and non-toxic PEG200 molecules as a precursor. The surfaces of the PP-PEG thin films were characterized by using contact angle measurement, X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), Fourier transform infrared (FT-IR) spectroscopy and time-of-flight secondary ion mass spectrometry (TOF-SIMS). Our results show that PP-PEG thin film surfaces deposited at low plasma power were very similar in chemical composition to the PEG polymer surfaces. In addition, these PP-PEG surfaces showed excellent non-biofouling property and biocompatibility during in vitro and in vivo tests. These results indicate that our PP-PEG thin films would be useful for practical biological applications.
