Tribological study showed that with the increasing of nanoscale roughness and combined with chemical modification, the tribological properties are greatly improved, which may be affected by real area of contact and the surface chemistry.
Surface energy was estimated by contact angle measurements and surface chemistry by X-ray photoelectron spectroscopy (XPS) as a function of the time during three months.
We investigate the relationship between the measured water contact angle, surface roughness, and surface chemistry, and determine the optimal silanization conditions that lead to the highest observed water contact angles.
Adhesion results for both horizontal and vertical surfaces are presented, with particular emphasis placed on the role of surface roughness, relative humidity, surface chemistry and contact pressure.
Both EDX analysis and contact angle data indicated that the surface chemistry of the beads themselves (both the hydrophobic and hydrophilic beads) was masked by the SU8.
Thus, this study suggests that combined effect of crystalline phase and surface chemistry controls blood-contact behavior of TNTs.
Surface chemistry was studied with water contact angle measurements performed using the commercial contact angle goniometer KSV CAM 200 (KSV Instruments Ltd., Helsinki, Finland) with an automatic dispenser and motorized stage.
The surface durability was evaluated by changes in wetting performance (contact angle measurements), surface morphology (SEM) and surface chemistry (FTIR, XPS).
Due to the fact that the bulk volume affects the surface chemistry, which functions as contact zone where adhesion takes place, variations in the cross-linking density could generate (for example, in polar surface groups) if respective end groups are available due to an incomplete reaction.
The surface chemistry of lithium electrodes in contact with NCPE revealed the formation of Li O C and LiN compounds.
