Surface wettability is considered as an important property of biological systems being closely tied to chemical and physical processes Superhydrophobic and superhydrophilic properties exist on polar extremes of surface wetting properties with both of the phenomena greatly investigated over the past two decades Superhydrophobicity is a celebrated feature of lotus leaves which are infamous for the innate self-cleaning ability arising from the presence of a hierarchically-structured hydrophobic surface1 Typically a superhydrophobic surface displays a water contact angle of over 150 and very low tilt angle 5 allowing water droplets to effortlessly roll off of the surface along with any contaminants and dust which is the same mechanism for the self-cleaning property of lotus leaves2 3 Likewise Superhydrophilic surfaces have also attracted significant attention in basic science and applied research drawing inspiration from natural systems like mosses and the compound eyes of mosquitoes4 Natural systems exhibiting such surface wetting limits depend on specialized compositions of texture and chemistry Through mimicking the natural structure we could artificially modulate the wetting ability ranging from superhydrophobic to superhydrophilic A diverse array of advantageous materials can be achieved for self-cleaning anisotropically dewetting water vapor harvesting and antifogging and antireflection 5 with the foreseeable applications in various areas such as water and snow non-adhesion on windows or antennas reduction of drag friction self-cleaning utensils microfluidic devices windshields solar cells Though a number of methods that have been investigated for generation of superhydrophobic and superhydrophillic surfaces including sol-gel plasma fluorination solidification of alkylketene dimer nanoparticle deposition and chemical vapor deposition techniques6 in the previous report most of the studies about the surface wettablity were focusing on developing solely superhydrophobic or superhydrophilic surface and none of them combines substrate independence with an economical and environmentally friendly approach Most recently by combining the properties of the lotus effect and marine mussel adhesion chemistry a superhydrophobic microbead construct based on
@Kibin is a lifesaver for my essay right now!!
