Langmuir blodgett
Langmuir-Blodgett (LB) technique, which involves the formation of interfacial layers and the subsequent transfer onto a solid substrate, provides one of the most versatile means to characterize the adsorption, self-assembly, and rheological properties of interfacial colloids. In this review, we summarized the relevant studies on anisotropic ...Two bottom-up approaches, Langmuir–Blodgett technique and drop-casting method allow us to control pC7F15MAA ordering; pC7F15MAA takes highly oriented monolayer formation by the LB technique, while it forms nanoparticle assemblies by the drop-casting method. Consequently, pC7F15MAA brings about a flat surface or three …Description. The development of oriented organic monomolecular layers by the Langmuir-Blodgett (LB) and self-assembly (SA) techniques has led researchers toward their goal of assembling individual molecules into highly ordered architectures. Thus the continually growing contribution of LB and SA systems to the chemistry and physics of thin ...
