Design, Fabrication and Characterization of Bio-Inspired Micro-Nano New Generation Polymer Fiber Array

Abstract

Design, fabrication and characterization of micro-nano bioinspired fiber array is the main idea of this thesis.Even though adhesion of the two surfaces together powerfully and easily separation from the same surface without leaving any trace is a desired phenomenon in most technological area, but it is seldom achieved in man-made structures. Nature has done this adhesion and separation phenomena (reversible adhesion) in various animals by fiber arrays on their motion foot during thousands of years. It is considered that this adhesion arises from molecular attraction force between surfaces (van der Waals forces). Gecko owes features listed here by toes (fiber structure found on foot ends of gecko), therewithal these are features which is tried to achieve in fabricated synthetic fiber arrays: Holding on smooth surfaces and surfaces with various roughness values, Have the power to carry weight up to hundreds times of its weight (adhesion force),
