“…There are many examples of vacuum plasma induced adhesion enhancement of polymers throughout the literature covering many years of study, with further examples and new approaches being added regularly. These range from the interfacial adhesion between fibres and a polymeric matrix being improved [13], enhancing the adhesive potential of polypropylene [14], polycarbonate [15], Tefzel © (poly(tetrafluoroethylene)-co-polyethylene) [16] etc (see the recent review of Durand for further examples [17]), to getting improved adhesion of polymer-metal compounds by adding a plasma polymerized acrylic acid coating [18]. Further examples can be found in the food packaging [19] and biomedical [20] industries.…”

An atmospheric pressure non-equilibrium plasma (APNEP) developed in the UK by EA Technology Ltd is currently being investigated in collaboration with the University of Surrey. Of the many applications of surface modification that can be induced using plasmas, adhesion enhancement is one of the most commercially important. In this paper, we illustrate the use of an atmospheric plasma to enhance the adhesion characteristics of low-density polyethylene (LDPE) and poly(ethylene terephthalate) (PET). The polymers were treated in the remote afterglow region of an atmospheric pressure plasma to avoid the thermal effects that can cause degradation for thermally sensitive materials when placed in direct contact with the plasma. Reactive (oxygen containing) and inert (oxygen free) atmospheric plasmas rapidly impart adhesion enhancement by a factor of two to ten as measured by 180° peel tests. However, extended exposure to the atmospheric plasma does not impart additional adhesion enhancement as the surface is ablated revealing the underlying polymer with poor adhesive characteristics. In contrast, vacuum plasma treated LDPE and PET show increased adhesion with extended plasma treatment. An adhesion enhancement in excess of two to three orders of magnitude was found to be achievable for vacuum plasma treatment times greater than 10 min.

“…In order to understand the physical significance of this curve shape, acid (γ + ) and base (γ -) components of the γ AB parameter were independently plotted as a function of the γ P parameter. As presented in Figure 6, while the γ + parameter remains virtually unchanged when an important increase in γ P is noted, the growth of γ -is proportional to that of γ esters, alcohols, ethers, peroxides and hydroperoxides has also been proposed [40]. In order to understand at a molecular-level the oxidation mechanism of the epoxy vinyl ester composite exposed to the atmospheric cold plasma shower, ATR infrared spectra of the composite surface were recorded.…”

“…However, prolonged surface etching by sulfuric acid may strongly influence the bulk rubber properties 49 . A surface modification technique widely described in the literature is cold plasma treatment (oxygen or nitrogen plasma) 49–77 . However, plasma treatment affects only the near surface of the rubber, leaving the bulk rubber untreated 49 …”

This study investigated novel methods for treating the surface of nitrile‐butadiene rubber to enhance its stability and resistance to thermal oxidation and aggressive media. The rubber surface was modified using 1,1,2‐trifluoro‐1,2,2‐trichlorethane. The study found that the duration of the modification strongly affected specific properties of the rubbers examined. It was observed that surface modification with 1,1,2‐trifluoro‐1,2,2‐trichlorethane improved the properties of nitrile‐butadiene rubber. Subsequently, the impact of the modification duration on morphology, thermal resistance, and chemical resistance was presented.
