“…Therefore, the values of the surface energy are not absolutely accurate. It is known that plasma treatment can produce a considerable amount of unsaturated bonds and free radical [11]. These unsaturated bonds and free radicals can react with oxygen to form polar groups on the fiber surface, which causes an increase in surface energy of the sample.…”

Polyacrylonitrile fibers were treated with a nitrogen glow-discharge plasma. The surfaces of untreated and treated fibers were examined with contact angle measurements, atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS). Surface energy calculations of the fibers were carried out from contact angle measurements using the relationships developed by Fowkes. It is found that plasma treatment causes a reduction in water contact angle on the fiber surfaces. The dispersion component of surface energy changes slightly, while the polar component is increased significantly from 14.6 mN/m to 58.7 mN/m and the total surface energy increase is 139%. The increase of surface energy is mainly caused by the introduction of hydrophilic groups on the fiber surfaces after plasma treatment.

“…Although there is an abundance of literature on the surface wettability of plasma treated materials [6][7][8][9][10][11], it is still not fully described from a theoretical point of view. The aim of the present study is to look further into the effect of plasma treatment on the surface energy and wettability of polyacrylonitrile fibers.…”

“…The applications of plasma treatment in textiles have been widely investigated, with a focus on improving several properties such as wettability, water repellency, soiling, soil release, printing, dyeing, and finishing processes. [1][2][3][4][5][6] Plasma treatments in textiles were generally carried out under low pressure (high vacuum). However, low-pressure plasma treatment for textiles is likely to be a batch process, which is time and energy consuming and therefore may not be economically feasible for many applications.…”

ABSTRACT:The effect of the air/oxygen/helium atmospheric plasma treatment on desizing polyvinyl alcohol (PVA) on cotton fabric was discussed as compared with the conventional H2O2 desizing. The possible change mechanism of PVA during atmospheric plasma exposure was induced through a combination of weight loss of PVA after plasma, PVA dissolving rate in water at room temperature, X-ray photoelectron spectroscopy, and Fourier Transform infrared spectroscopy.

To eliminate the temperature influence on pressure sensor, high birefringence photonic crystal fiber is introduced to fiber loop mirror to sensing pressure.In the pressure 0∼1.5 Mpa range, pressure sensor with the sensitivity of 3.76 nm/Mpa is realized theoretically and experimental. Also, a novel demodulation method with the sensitivity of 6.67 dB/Mpa is proposed that changing the wavelength shift into power, which decreased the cost sharply. © 2012 Wiley Periodicals, Inc.
