RF-CF4 plasma surface modification of paper: Chemical evaluation of two sidedness with XPS/ATR-FTIR

Effects of Treatment Time by Sulfur Hexafluoride (SF6) Plasma on Barrier and Mechanical Properties of Paperboard

“…The results show that plasma treatment can decrease the strength of paperboard, which conforms to other research . This is because broken cellulose chains are produced under the influence of particle bombardment …”

“…Water resistance, which is a typical characteristic of fluorinated polymers, can be imparted to natural fibres through the application of fluorine‐containing resins, thus creating outstanding water resistance properties. On the other hand, low‐temperature plasma treatments are known to induce physical and chemical surface changes in polymers through etching, grafting, polymerization and/or cross‐linking processes, without changing their bulk properties . Plasma species do not penetrate below about 10 nm of the surface; therefore, the rest of the paperboard's chemical structure remains totally unmodified during the plasma treatment …”

“…On the other hand, low-temperature plasma treatments are known to induce physical and chemical surface changes in polymers through etching, grafting, polymerization and/or cross-linking processes, without changing their bulk properties. [29][30][31][32][33] Plasma species do not penetrate below about 10 nm of the surface; therefore, the rest of the paperboard's chemical structure remains totally unmodified during the plasma treatment. 31,34,35 Because demand for environmentally friendly packaging using renewable resources with high water resistance and oil barrier properties is increasing, further investigation on the effect of plasma technology on biodegradable packaging materials such as paperboard is needed.…”

Enhanced cellulosic hydrogen production from lime-treated cornstalk wastes using thermophilic anaerobic microflora

“…Table 2 summarizes the theoretical O/C atomic ratios and relative C1eC3 peak areas of the main components of the cornstalk. The deviation of the observed O/C ratios and relative abundance of C1eC3 from theoretical values can be used to provide qualitative characterization of its surface chemical composition after lime pretreatment [29,30].

Surface modification of a polyamide 6 film by He/CF4 plasma using atmospheric pressure plasma jet

“…The modification effects of plasma treatments may include improving surface hydrophilicity and roughness for enhanced wetting, dyeing, printing and adhesion properties [4][5][6]. Under the bombardment of active species generated by a homogeneous plasma, polymer surfaces can be modified by removing surface contaminations [7,8], introducing new chemical functional groups [9][10][11][12][13][14], and depositing a thin coating [15][16][17]. However, most of the plasma systems operate under a low pressure and require an expensive and complicated vacuum device [18].…”
