“…The presence of anhydride groups is confirmed by the presence of two peaks in the high resolution spectra of the O (1 s) corresponding to oxygen doubly bonded to carbon (ÀC=O) at 532.5 eV and oxygen singly bonded to carbon (O=CÀOÀC=O) at 533.8 eV. These results are in agreement with previously published data [13,15,16]. Complete coverage of the underlying aluminium substrate was confirmed by the absence of any Al(2p) signal showing through.…”

“…A mixed locus of failure (mainly cohesive in EPDM very close to the EPDM=plasma polymer interface) is obtained. This approach offers great flexibility in that the density of such alkene functionalities at the surface can be easily tailored by simply programming the pulsed plasma duty cycle [13].…”

“…The optimum deposition conditions correspond to: power output ¼ 5 W, pulse on-time ¼ 25 ms, and off-time ¼ 1200 ms. These parameters were previously optimised on the basis of a full factorial design and a central composite approach to get maximum maleic anhydride concentration in the polymer coating [13]. Upon completion of deposition, the R.F.…”

High interfacial strengths of elastomer to metal joints imply the formation of covalent bonds at the interface. It is proposed to deposit a plasma polymer coating containing double bonds on an aluminium substrate for the formation of crosslinks between the elastomer and the coating during peroxide crosslinking of the elastomer. Ethylene-co-propylene-co-diene terpolymer (EPDM) is considered here. Maleic anhydride is polymerised and reacted with allylamine to lead to an amide functionalised plasma polymer which is heated to produce imide functional groups. Plasma polymer coated aluminium=EPDM joints were evaluated by a peel test and the locus of failure was identified by several techniques: SEM, infrared spectroscopy, wettability, and XPS.

In contrast to most of the existing literature on plasma polymerization of acrylic acid (AA), not only the chemical structure and film thickness of the deposits were studied, but also a new way to obtain COOH-rich surfaces were studied. This is an important aspect when applying the obtained coatings for biomedical and electronics applications. Therefore, acrylic acid/CO 2 polymer films with a thickness of ca. 150 nm were deposited in the pulsed plasma regime onto polyethylene and aluminum. Their structure-property relationships were studied in dependence on the mixture ratio of acrylic acid monomer and CO 2 gas. The influence of the CO 2 gas on the regularity and functionality of plasma-deposited poly(acrylic acid) (PAA) was studied in detail using bulk-sensitive (FTIR) as well as surfacesensitive methods, such as X-ray photoelectron spectroscopy. Results obtained show, in presence of a small amount of CO 2 gas within the acrylic acid plasma, a structure of PAA with high concentration of COOH groups was estimated. A polymer network is obtained with an increasing abundance of branched groups for AA/CO 2 with increasing CO 2 gas in the mixture.

“…The powder mixtures were contained in reactor tubes connected to the inlet of a low-temperature vacuum r.f. plasma reactor as described before [23]. Under evacuation of the plasma reactor, the monomer vapor was introduced in the reactor by sublimation at a constant flow rate of approximately 1.6 x 10 -9 kg s -1 .…”

In a trend for sustainable engineering and functionalisation of surfaces, we explore the possibilities of gas phase processes to deposit nanocomposite films. From an analysis of pulsed plasma polymerisation of maleic anhydride in presence of nanocellulose whiskers, it seems that thin nanocomposite films can be deposited with various patterns. By specifically modifying plasma parameters such as total power, duty cycle, and monomer gas pressure the nanocellulose whiskers are either incorporated into a buckled polymer film, or single nanocellulose whiskers are deposited on top of a polymeric film. The density of the latter can be controlled by modifying the exact positioning of the substrate in the reactor. The resulting morphologies are evaluated by optical microscopy, AFM, contact angle measurements and ellipsometry.
