“…It is evident that the introduction of NDs into the polymeric matrix increases the adhesion force (P adh ). It should be noted that by using a hydrophilic silicon nitride (Si 3 N 4 ) tip for the force measurements, increased adhesion is exhibited to a hydrophilic surface compared to a hydrophobic surface; the measured adhesive forces are therefore a direct indication of the hydrophilicity of the sample surface [64].…”

“…Si 3 N 4 is hydrophilic material that interacts more strongly with hydrophilic substances than with hydrophobic ones [59]. Thus, the measured adhesion between the tip and polymer provides information on the nature of the sample surface.…”

Atomic force microscopy (AFM) has been used to study the effect of various photoinitiators doped into poly(methyl methacrylate) (PMMA) on the mechanical properties of PMMA films at the nanometer scale. Pure and modified PMMA films (containing four different photoinitiators) were exposed to a mercury vapor lamp in air atmosphere. Force-distance curves for hardness, Young modulus, and adhesion forces were obtained using different AFM modes (tapping or contact-mode) and different tips (diamond or silicon nitride). The results revealed that the added photoinitiators slightly changed the nanomechanical properties of PMMA as a result of alterations in the photochemical reactions and physical processes occurring in the studied systems. tert-Butyl peroxybenzoate had the most efficient effect on the measured parameters in UV-irradiated PMMA, whereas benzoyl peroxide was less active. The mechanism of the observed processes is discussed.

“…[1][2][3] Especially in electric power industry, PDMS-based silicone rubber insulators are currently replacing conventional inorganic ceramics for high-voltage applications because of their light weight, good dielectric property, and excellent water repellency. [4][5][6][7][8] Owing to the hydrophobic methyl groups and low free surface energy, surface hydrophobicity is one of the most important factors that contributes to the superior performance of preventing moisture from silicon rubbers. [5][6][7] However, if insulators have been in service for long time, the initial hydrophobic surface would be altered to be hydrophilic.…”

A series of silicone rubber samples with di®erent cyclosiloxanes contents have been successfully prepared, and their hydrophobic recovery behaviors and mechanism were investigated in detail. The gas chromatography-mass spectroscopy technique after Soxhlet extraction was utilized to examine the low molecular weight siloxanes in the sample, SEM was used to observe the surface morphology of the silicone rubber in°uenced by plasma treatment, and contact angle measurement was applied to probe the hydrophobic recovery of the sample surface after plasma treatment at di®erent storage temperatures. The storage time-dependent contact angle of water can be well tted by the di®usion model calculated from Fick's second law. The results imply that the hydrophobic recovery of silicone rubber is related to the di®usion of low molecular weight siloxanes, while larger content or higher temperature can induce faster hydrophobic recovery.
