“…After 55 days, the results show that all of the surface‐treated nanofibers lost hydrophilicity (by considering the standard deviation). Similar losses in hydrophilicity have been observed for many plasma‐treated polymers . For instance, Wavhal and Fisher found that after Ar plasma treatment, the hydrophilic modification of a polyethersulfone membrane was not permanent, and a change in contact angle was observed within two days of plasma treatment.…”

This paper provides a comprehensive analysis of microwave‐induced low‐vacuum argon plasma treatment effects on the hydrophilic stability of various polymeric nanofiber webs. After plasma modification, samples are kept dry at room temperature in a dark place for the experiments, and the wettability of the nanofibers is improved by plasma treatment. The stability of the plasma‐treated hydrophilic nanofiber webs is observed for 55 days using water contact angle measurements. Different polymeric nanofiber webs show different stability. Based on the contact angle measurements, the surface starts to lose hydrophilicity during the first week after plasma treatment. The structural changes are examined by pore size measurements, scanning electron microscopy, and Fourier transform infrared spectroscopy. Two of the selected nanofiber webs are used as microfilters for separation of oily wastewater with a cross‐flow separation unit to measure the effect of the plasma treatment under wastewater. The permeability and selectivity of the plasma‐treated and untreated samples are compared. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46751.

“…As we reported previously RESULTS AND DISCUSSION (14), these changes are attributed to the formation of hydroxyl, carbonyl, and carboxyl groups. Washing with methaChemical Changes in the Surface with O 2 Plasma nol caused the spectrum to lose intensity on the high-energy Treatment side of the main peak.…”

“…We have already reported the changes in surface characteristics of several O 2 -plasma-treated polymers during aging (14,15). However, the dynamic behavior of the oxygencontaining functional groups introduced into the polymer main chain has not been clearly distinguished from the diffusion of the low-molecular-weight compounds formed by the plasma treatment.…”

“…In the examined conditions we were able to get grafting yield in the range from 0.3 to 12.4 l g/cm 2 . It is clearly seen that yield increases with plasma treatment time (see samples GS 1 -3, and GS 13 vs GS 5) what is in agreement with some literature data [10,11,15].…”

Polysulfone membranes were modified with acrylic acid using plasma initiated graft polymerization (both in solution and vapor phase) and plasma polymerization. Changes on the surface were monitored by contact angle measurements and FTIR‐ATR technique. Pore size and ultrafiltration properties were also evaluated. Grafting in solution gave as a result hydrophobic membranes with pore size diameter signficantly reduced. Such membranes lost their ultrafiltration properties. Grafting in vapor phase seems to give brush‐like structure. Membranes possess hydrophilic surface and unique filtration properties in basic environment. Plasma polymerization of acrylic acid on the PSU surface creates a layer of material highly reminding pure poly(acrylic acid). Performance of such membranes was also pH‐dependent showing better properties in basic solution.
