A kind of lotus and fill effect of multifunctional disclosed micro structure, each unit is composed of several pieces with the same and different height, triangle triangular wall section, each spaced or staggered, from high to low order surface, forming intermediate layer layer number to zero and the bottom surface; as a straight line, the middle layer can be formed on the surface of open or closed and the bottom space, and other layers to form a closed space; the top section of the wall is smooth on the triangle convex curve, used to reduce rupture of liquid drop to touch the triangle wall, reduce the droplet falling velocity of the kinetic energy and the formation of closed space; the air spring will drop rebound; due to the invention of surface linear, droplet surface static in the small contact area, a superhydrophobic surface of droplets, and the droplets rebound combined with the liquid droplet ejecting structure surface: Many of the triangular wall surface will be reflected downward light and refraction, caused by light effect; the invention has the advantages of high structural strength, easy molding and mass production advantages.

兼具莲花与补光效应的多功能微结构
本专利技术涉及一种兼具莲花与补光效应的多功能微结构。
技术介绍
环保与洁净能源是全世界极为重要的问题,太阳能发电则是主要的洁净能源发电装置;但太阳能面板常因表面受到污染而大幅降低发电效率,同时,太阳光在太阳能面板表面上亦易于反射,因而降低了发电效率;因此,如太阳能面板上,能有一兼具莲花与补光(lotusandlighttrapping)效应之表面,将可大幅提高太阳能面板的发电效率。而所谓莲花效应是指一表面,除了液滴与固体表面间之静态接触角(contactangle)大于150度外,当液滴自一相当高度落于表面时,液滴亦将反弹与滚动,藉此可达到自洁之功能;若该表面静态接触角大于150度,但不具反弹与滚动的特性,则只能称为具静超疏水性(staticsuperhydrophobic);自然界中有诸多物种,天生即具备超疏水性之表面,其中以莲叶之莲花效应(lotuseffect)最为知名。莲叶表面透过电子显微镜(scanningelectronmicroscope,SEM)观察后,如图1所示,可知莲叶表面具有约20μm之突柱,突柱之间距表皮细 ...
