“…The upper results comply with Timell (1986) and Gardner (2016) stating that wood species with higher extract content (sessile oak, spruce) manifest higher contact angle, relative to the ones having lower extract content (beech, birch) on surfaces prepared in the same way (see envelopes on Fig. 3).…”

“…According to Gardner et al (2016), in case of differently rough wood surfaces the quality and quantity of polymer constituents of the cellwall, influence the wettability of the machined surface. According to Piao et al (2010), earlywood -having thin cellwalls and larger lumen diameter -manifests higher wettability than latewood portions with thick cellwalls and smaller lumen diameter and according to Timell (1986) earlywood has higher lignin content because earlywood cells have thinner walls.…”

“…The surface tension of solid (γ s ) contains both polarity component ( γ s p ) and dispersion component ( γ s d ) It can be calculated with geometric‐mean equation :

γ_{normals} = γ_{normals}^{normalp} + γ_{normals}^{normald}

γ_{LV} (1 + cos θ) = 2 (γ_{normalL}^{normald} γ_{normalS} {^{normald})}^{1 / 2} + 2 (γ_{normalL} p γ_{normalS} {^{normalp})}^{1 / 2} .

MC nylon‐6‐b‐polyether amine(PEA)copolymers were synthesized with macroinitiator based on amino‐terminated PEA functionalized with isocyanate via in situ polymerization. It was found that introduction of PEA delayed the polymerization process of caprolactam, resulting in the decrease of molecular weight of the copolymer. With increasing content of PEA, the melting peak started declining and widening, while the crystallinity and crystal grain size decreased, indicating weakening of the crystallization ability of nylon‐6 matrix. The fracture surfaces of the copolymer changed from irregular mosaic to the striation, presenting tough fracture characteristic, and the notched impact strength of the copolymers were improved dramatically. The electrical resistivity of the copolymers was increased by three orders of magnitude, and kept stable with prolonging storage time, indicating a permanently antistatic ability. The improved antistatic mechanism was deduced by the increase of concentration of oxygen atom and CO group on the surface of the copolymers with increasing PEA content. The water contact angle decreased and surface tension increased, and finally the hydrophilicity of the copolymers was enhanced, resulting in the fairly good antistatic behavior of the copolymers by absorbing moisture from air.

“…First, the Hamaker constant and the acid-base energy constant between the InGaAs surface and the silica particle in the solution can be estimated from the surface energy components of InGaAs and SiO2 (5). In this study, the surface energy components of InGaAs and SiO2 were calculated from the contact angles of DIW, ethylene glycol, and αbromonaphthalene using Young-Good-Girifalco-Fowkes equation (6). As shown in Fig.…”

The adhesion of silica particles on an InGaAs surface in a 1/1/100 NH4OH–H2O2–H2O mixture (APM) solution was investigated. To control the particle adhesion on InGaAs surface, hexadecyltrimethylammonium bromide (CTAB) was added to the APM solution at concentrations of 10-4–10-2 M, and its effect was examined. To understand the adhesion behavior of silica particles on the InGaAs surface in the APM solution with the addition of CTAB, Lifshitz–van der Waals energy, acid–base interaction energy, and electrostatic energy were estimated. In addition, energy barrier was calculated from the changes in those energies. It was found that the behavior of the energy barrier was strongly related to the adhesion behavior of the silica particles on the InGaAs in the APM solution with different concentrations of CTAB. Therefore, the addition of CTAB changes the interaction force and the energy for particle to adhere to the InGaAs surface.
