Deposition penetration depth and sticking probability in plasma polymerization of cyclopropylamine

Low-temperature atmospheric pressure plasma deposition of TiO2-based nanocomposite coatings on open-cell polymer foams for photocatalytic water treatment

“…Moreover, to date, published studies have been mainly limited to the use of flat substrates and, therefore, additional efforts are still needed to achieve the deposition of well-structured TiO 2 -based films on complexgeometry supports. Interestingly, in the last few years, AP low-temperature plasmas have been successfully proposed for the surface modification of 3D porous materials [45][46][47][48][49][50][51]. It has been shown that, for instance, the careful optimization of the plasma reactor configuration and operating conditions can lead to the deposition of a thin film on both the outer and inner surfaces of the treated samples.…”

A Study of Plasma−Porous Carbon−Co2 Interactions: Ammonia Plasma Treatment and Co2 Capture

“…At a pressure of 80 Pa used in our experiments, the Debye length is in the order of 10 −1 mm similar to that in ref. 54 At this Debye length, which is much greater than the pore widths of the AC-A sample estimated to be ≈0.5 nm, ≈1 nm, ≈4 µm by CO 2 , Ar and Hg porosimetry respectively, the plasma could not have extended into such depths.…”

“…52,53 In a recent study, LP (50 Pa) plasma polymerisation of cyclopropylamine on a variety of substrates with different 3D geometries was investigated in terms of the deposition penetration depth and the uniformity of film chemistry. 54 One of the substrates studied was polycaprolactone nanofibrous mats which had an average pore diameter of ≈1 µm.…”

Enhanced Adhesion of Electrospun Polycaprolactone Nanofibers to Plasma-Modified Polypropylene Fabric

“…At low pressure, the PP fabric was modified by oxygen plasma treatment or by plasma-enhanced chemical vapor deposition (PECVD) of amine plasma polymer (amine-pp) film from cyclopropylamine (CPA, 98%, Merck, Darmstadt, Germany) vapors mixed with argon. The modifications were carried out in a ultra-high vacuum stainless-steel reactor with parallel plate electrodes 210 mm in diameter, described in detail in previous publications [ 46 , 47 ]. The bottom electrode was capacitively coupled to a RF generator working at a frequency of 13.56 MHz.…”
