A simple method to improve the photoelectrochemical performance of TiO2 NTs by simple air plasma post-treatment is reported. The photocurrent density and IPCE are 3–4 times higher than that of the pristine TiO2 NTs even after six months.

Air Plasma Treatment

Surfaces of bamboo derived cellulosic fibrous systems have been modified by air-plasma treatment. Their deformational response was studied to establish the relationship between their three-dimensional profile and permanent deformation as a measure of their comfort properties since the fibrous system made of natural polymer comes into contact with the skin. The composite should have a permanent deformation close to zero, in order to be, in terms of dimensions, as stable as possible. By analyzing the area of 1 cm2 using a Universal Surface Tester (UST), different 3D surface diagrams and surface roughness values were obtained. This type of surface investigation provides relevant information about the permanent deformation response of the studied surface, for comfort purposes. The deformation responses and roughness levels were studied (the roughness being the parameter quantifying the 3D geometry of the systems surface). The effect of air-plasma surface modification on the deformation response of bamboo derived cellulosic fibrous systems and optimization of their 3D surface structure to enhance comfort-related properties proved to be substantial. The surface modifications induced by air-plasma treatment are in a good correlation with the mechanical behavior. As expected, the roughness levels of samples studied using ball sensors are higher than those of specimens scanned using a papillary sensor. Knitted polymer fibrous matrix T1 shows a roughness level of 773 μm resulting from analyses using the ball sensor, while using the papillary sensor it was 102 μm, 86.8% less than before. The analysis of the dimensional stability of knitted polymer fibrous systems was performed by scanning with the papillary sensor, since it provides information comparable with human perception concerning the architecture of the sample surfaces.

Air Plasma Treatment

Low-temperature air plasma was used to treat the cellulose membranes by varying the period of time from 10 to 30 minutes. The surfaces of membranes were changed from hydrophobic to hydrophilic membranes. The contact angles of treated membranes were increased when increasing time to treat. The surface modifications of membrane before and after treated were characterized by SEM. It is shown that air plasma treatment is used to improve the roughness. The dielectric property was also studied.
