, J. R. (2014). Photo-initiated chemical vapor deposition of thin films using syngas for the functionalization of surfaces at room temperature and near-atmospheric pressure. Surface and Coatings Technology, 244, p. 98-108. doi:10.1016/j.surfcoat.2014 This study addresses the current limiting factor, namely the cost issue, by using simple gas precursors, using an a↵ordable initiation source and operating under normal condition. This approach di↵ers from the current approaches which use expensive solvents as precursors, energy consuming-sources of initiation (e.g.high temperature, plasma and VUV) and operate under high vacuum and/or high temperatures. While the current paradigm is to target the peak absorption of a molecule, the present study indicates that long chain polymerized products can be formed from o↵-peak wavelength. It has been found that photo-initiated deposition occurs and that a wide range of water contact angles, from 5 to 118 , can be obtained by manipulating the experimental conditions. A multilinear empirical model has been derived, and it predicts fairly well the contact angles obtained as a function of the di↵erent experimental parameters.
