Parahydrophobic surfaces (PHSs) composed of arrays of cubic 渭-pillars with a double scale of roughness and variable wettability were systematically obtained in one step and a widely accessible stereolithog. Formlabs 3D printer. The wettability control was achieved by combining the geometrical parameters (H = height and P = pitch) and the surface modification with fluoroalkyl silane compounds Homogeneous distribution of F and Si atoms onto the pillars was observed by XPS and SEM-EDAX. A nano-roughness on the heads of the pillars was achieved without any post-treatment. The smallest P values lead to surfaces with static contact angles (CAs) >150掳 regardless of the H utilized. Interestingly, the relationship 0.6 鈮?H/P 鈮?2.6 obtained here was in good agreement with the H/P values reported for nano- and submicron pillars. Furthermore, exptl. CAs, advancing and receding CAs, were consistent with the theor. prediction from the Cassie-Baxter model. Structures covered with perfluorodecyltriethoxysilane with high H and short P lead to PHSs. Conversely, structures covered with perfluorodecyltrimethoxysilane exhibited a superhydrophobic behavior. Finally, several aqueous reactions, such as precipitation, coordination complex, and nanoparticle synthesis, were carried out by placing the reactive agents as microdroplets on the parahydrophobic pillars, demonstrating the potential application as chem. multi-reaction array platforms for a large variety of relevant fields in microdroplet manipulation, microfluidics systems, and health monitoring, among others. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2COA of Formula: CuH2O2).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. The transition metal-catalyzed chemical transformation of organic electrophiles and organometallic reagents has turned up as an exceedingly robust synthetic tool. Due to these characteristics, copper nanoparticles have generated a great deal of interest especially in the field of catalysis. COA of Formula: CuH2O2
