Adhesion Characterization of micro components fabricated by Micro stereo lithography
Journal Title: REST Journal on Emerging trends in Modelling and Manufacturing - Year 2017, Vol 3, Issue 1
Abstract
Interfacial adhesion of UV curable polymers is important in Micro stereo lithography (MSL) due to the sticking problems during separation from their substrate and insuring adhesion between two dissimilar materials used in micro-fabrication. Therefore, standardizing quantitative ranking among different substrates helps to select the required substrate for fabrication of polymers according to their application. In this report, Nano Indentation techniques is proposed and used to perform experiment on interfacial adhesion of HDDA (1, 6 Hexanediol Diacrylate) polymer over Teflon Substrate. The Nano-indenter is used to perform bending test on HDDA polymer from which the interfacial adhesion is easily analysed. Finally, interfacial adhesion of HDDA on Teflon is obtained from the computerized Nano-indenter machine and measured with an appropriate measurement unit.
