“…Techniques based on non-equilibrium plasmas are still of growing interest in a wide field of industrial applications: surface treatments applied to metals [1,2] or non-metals [3][4][5] to improve their properties (hardness, resistance to corrosion and wear), sterilization of surfaces of medical instruments [6,7], cleaning of oxidized steel surfaces [8] or generation of nanostructures such as nanotubes [9] or crystalline nanoparticles [10]. Typically, these applications require reactive gases with complex chemistries, which are strongly influenced by the discharge dynamics.…”

This paper presents the spatial characterization of Ar plasma induced by a broad-band helical coupling device at low pressure (15 Pa). The electric field analysis outside the helix but within the coupling device is carried out by electrostatic probe for several excitation frequencies ranging from 13.56 to 433 MHz. The results prove that this helical cavity behaves as a slow-wave plasma source. At 13.56 MHz, the spatial investigation of electric field with and without plasma led to show a flat profile along the helix structure. At this frequency, the plasma is studied by spatially resolved emission spectroscopy and by means of a double Langmuir probe in order to evaluate the densities of some characteristic species (electron and Ar emitter) and the electron and gas temperatures. These temperatures are invariants along the discharge with average values about 400 ± 50 K and 2.3 ± 0.6 eV for gas and electron, respectively. Consequently, the electron energy distribution function and argon ground state density are also constant along the discharge. No variation of the argon metastable density, estimated by means of a simplified kinetic model, could be shown and an average value equal to 9 × 1017 m−3 is obtained. In contrast, the density profiles of electron and Ar emitter show a minimum situated in the middle of the helical structure and two maxima located at the positions where the RF power is transmitted to the gas and at the end of the helix. The electron density values vary from 3 × 1016 to 1017 m−3. According to the low pressure conditions and the flat evolution of the electric field, these hollow shaped density profiles can be explained as a consequence of a non-linear phenomenon.

“…While plasma functionalization is the process of introducing chemical groups already existent in the plasma gas itself, grafting is differentiated by adding a monomer that bonds to the polymer. [19,96] Plasmainduced grafting has a distinctive advantage over traditional chemical methods because it does not require initiators. However, the radical formation on the polymer substrate and grafted monomer by plasma is random, while chemical reactions always happen at the same sites and thus are more controllable.…”

Plasma surface modification of polymers is a well‐established method applied to increase the surface energy of these materials, where the capacity of cold plasmas to generate free radicals and functionalize the surface with polar groups is widely reported in the literature. This article provides a comprehensive literature review on plasma surface treatment, plasma‐induced grafting, and plasma polymerization, evaluating how these techniques can be applied to modify the bulk properties of polymers. A novel process of plasma‐induced polymer bulk functionalization in the melt state is introduced, where an atmospheric pressure plasma jet could be applied to a continuous reactive extrusion process, enhancing the production of graft copolymers for compatibilization of polymeric blends and fiber composites.

In this paper，lower polyethylene(LDPE) was melt to graft maleie anhydride (MAH) in reactive extruder by using dicumyl peroxide(DCP) and benzoyl peroxide(BPO) as the initiator. It can be found that MAH has been grafted to LDPE large molecular chain using by infrared spectrum and graft rate measurement. Orthogonal experiments were employed to confirm the influences of initiator, MAH and LDPE. The results showed that the reaction graft ratio firstly increased，then began to decrease with the increasing of the contents of MAH and initiator. The maximum shear strength was at 2.12MPa when graft polymer was used to adhesive the board of aluminum and polyethylene. The graft rate of graft polymer was at 15.68%.
