Adhésion Carbonate de calciumLe carbonate de calcium (CaCO3) est composé d'un ion carbonate (CO32-) et d'un ion calcium (Ca2+), sa masse molaire est de 100,1 g/mole.
C'est le composant principal du calcaire et de la craie, mais également du marbre. C'est aussi le principal constituant des coquilles d'animaux marins, du corail et des escargots. Composites à fibres Dioxyde de silicium Hydrophobie Traîtements de surface

Résumé : |
A simple method is reported for the preparation of superhydrophobic fiber reinforced plastic (FRP) surfaces with controlled adhesion. By simply adjusting the content of CaCO3 and SiO2 of surface coating, after surface treatment, we can obtain the different FRP surfaces with diverse morphologies. The results confirm that the FRP samples not only could achieve superhydrophobicity but also present huge differences in adhesive abilities. The microlens surface presents a strong sticky performance which can hold a 10-μL water droplet even tilted vertically or turned upside down. Such a property is very similar to the rose petal effect. In comparison, the microbowls surface presents a slippery property which can be regarded as a lotus effect. The water roll-off angle is as low as of approximately 9°. At the same time, the adhesion work of the surfaces is decreased from extreme high (34.7 mN/m) to very low (7.9 mN/m). Noticeably, the heat resistance and antifriction of the microbowls surface are better than that of the microlens. |
