“…Surface chemical modification can be performed through the surface grafting, onto polymer films, of suitable monomers containing functional groups that can be used for further reactions. In this way, functional groups such as amine, imine, hydroxyl, carboxylic acid, sulfate, and epoxy groups can be incorporated onto the surface of a broad range of conventional polymeric substrates, most of which have a nonpolar, less reactive surface 11. Surface grafting may proceed by free‐radical mechanisms generated by oxidants such as Ce +4 ions12 and peroxide initiators 13.…”

The modification of polyethylene by the grafting of poly(acrylic acid) onto the surface of one of the faces of low-density polyethylene films with UV radiation is reported. The transport of oxygen, nitrogen, carbon monoxide, carbon dioxide, methane, ethane, ethylene, propane, and argon across surface-modified films containing 3.7% poly(acrylic acid) has been investigated at several temperatures. The layer of poly(acrylic acid) grafted onto the surface of one of the faces of the films reduces the permeability coefficient of the gases by a factor of about 1/6. The sharp drop in the gas permeability as a result of the poly(acrylic acid) layer may arise either from the formation of ordered structures of the grafted chains or from the development of highly crosslinked structures. The values of the polymer-gas enthalpic interaction parameter for the modified film are higher than those for the unmodified one.

“…4,5 The surface treatment of the chemical compounds in silicon rubber or vulcanized rubber is usually performed by using a glow discharge or a corona discharge. 2,6,7 Modifying a polymer surface of a low-temperature plasma through glow discharge or corona discharge does not directly influence the characteristics of the polymer material itself; only the modification of the surface layer is capable of having that effect. The use of an excimer laser is a dry process, compared to the others that are generally wet, and it not only simplifies the surface modification process but it also saves water resources that are used largely for cleaning the surface.…”

Surface treatment using an excimer pulse laser beam has been conducted in order to increase the adhesive strength of vulcanized rubber. The adhesive strength increased with increasing the number of irradiation time with laser pulses and reached to 1,500 N/m after 100 cycles of irradiation. Increased in energy density was directly proportional to the improvement of the adhesive strength. Maximum value of the adhesive strength of 1,500 N/m obtained at the energy density of 176 mJ/cm 2 . We conclude that an increased energy density improves in both the surface area and adhesive strength.

“…This energy transfer process continues until one of the atoms is knocked out into the vapor phase. In our previous study, 10,11 we reported that ablation played an important role to decrease hydrophilic surface properties and surface topographies for the immobilized poly(ethylene) (PE) surfaces with acrylic acid by Ar plasma.…”

The ablation effects of Ar-plasma treatment and alkali-decomposition behavior in NaOH solution of polyethylene terephthalate (PET) film were investigated. The modifications were evaluated by analysis of atomic force microscopy topographical changes, and by the measurement of decomposition yield in conjunction with heats of formation and electron densities of acyl carbon calculated by Parameterization Method 3 method. It has shown that the alkali-decomposition is hampered by plasma treatment and its decomposition yield is closely related with plasma treatment conditions such as exposure time to plasma. Plasma-treated PET films exhibited lower decomposition yield, compared to that of virgin PET. Increasing plasma exposure time contributes positively to decrease the decomposition yield. It has also shown that the topography of PET surface was affected by the base-promoted hydrolysis as well as Ar-plasma treatments. These behaviors are attributed to the decreased nucleophilicity of acyl carbon damaged by the ablation of Ar-plasma.
