“…There was no significant difference in CA values between PA-g-PMMA 164 -Br and PA-g-PS 66 -Br because of the nature of the grafted polymer. Although the contact angles values were not correlated with the local texture of the fabric, the dramatic differences between unmodified and modified fibers confirm the polymer growth on the fibers' surfaces [39][40][41]. and the contact angles dramatically increased to 118° and 115°, respectively.…”

A totally new approach in the synthesis of mixed polymer brushes tethered on polyamide (PA) surfaces is presented herein. As a proof of concept, two types of homopolymers were synthesized in sequential surface-initiated atom transfer radical polymerization (SI-ATRP) reactions: poly(methyl methacrylate)/poly((2-dimethylamino)ethyl methacrylate) and polystyrene /poly((2-dimethylamino)ethyl methacrylate). The ATRP initiator was immobilized on the surface through PA chain-end groups in two subsequent steps, separated by homo-polymerizations. The amount of the PA chains’ end groups available on the modified surface was tuned by the thermal rearrangement of the surface.

“…If they changed only the value of b the water contact angle would increase for the microstuctured surface with increasing b value but for the hierarchical structured surface, the change in the contact angle value is negligible and there is no tell-dependency. Cansoy et al [54] measured water contact angles on surfaces with two types of pillars: square and cylindrical. The pillar separation distance, s, changed from 20 to 40 m and the advancing contact angle changed slightly as a function of s but independent of the pillar shape.…”

“…As usual, the Cassie -Baxter mode [29,30] is employed here in an attempt to understand the large increase of the hydrophobicity on patterned surfaces with pillars and dimples ( figure 3). From a previous study [18], the wettability of a surface decorated with large, simple micropatterns was commonly configured in the transition from the Wenzel to Cassie -Baxter mode.…”

Inspired by biological topographical surfaces, micropatterned elastomeric surfaces with square pillars and dimples of different geometry scales were fabricated. Their wettability and adhesion properties with various liquids were systematically investigated and compared with flat surfaces. Interesting results were obtained in the case of silicone oil (the toe-pad-like wetting case) in that the scale-dependent wettability and adhesion performed inversely for pillars and dimples. Micropillars significantly enhanced the surface wettability with a geometry scale dependence, whereas the dimples suppressed the wettability independent of the geometry scale. The adhesion force of the micropillars increased with an increase of the geometry scale. However, in the case of the micro-dimples, the adhesion force obviously decreased with an increase of the geometry scale. This behaviour was attributed to the fact that pillars are ‘open’ to oil but dimples are ‘close’ to oil, presenting different orientations to the solid–liquid interface.
