In this work, plasma-polymerized cyclohexane (PPCHex) thin film, which can be used as a non-biofouling surface for proteins, was characterized by using time-of-flight secondary ion mass spectrometry (TOF-SIMS) along with a principal component analysis (PCA), X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy. The PPCHex thin film was deposited on a glass surface by using the inductively coupled plasma chemical vapor deposition method and cyclohexane as a precursor. The non-biofouling property of the PPCHex surface was controlled in a reproducible manner as a function of sample bias plasma power and was correlated with the surface chemical composition and hydrophobicity of each surface. In addition, a PCA of the TOF-SIMS data provided insight in a systematic manner into the surface chemical compositions and molecular cross-linking on plasma-polymerized thin films as a function of sample bias plasma power.
