In this study, polymers, their definition and history, and some examples of the most important ones have been explained. The major manufacturing processes for polymer product making and especially thin film polymers also have been described. Polyvinylidene Fluoride (PVDF), which is the focus of this thesis discussed in details and chemical physics and the molecular structures and different configurations of its crystalline assembly and their properties discussed in details. Several PVDF powders and different solvents acquired, the major affective parameters and conditions investigated, and the best ratios and processes in order to achieve the desired solution proper to use for electro-spinning procedure reported. Micro 3D structured features fabricated from SU-8-100 photoresist on the Silicon wafer substrate and all the steps, conditions, chemicals and instruments have been fully described. Electro-spinning machine, its functions and fundamentals explained and one designed, built and used to investigate the properness of this method for depositing PVDF polymer on micro 3D structures. The surface quality and the evaluating measurement tools and techniques have been described. Scanning electron microscope (SEM) as the major evaluating tool used and many experiments with different conditions and parameters set-up conducted to investigate the uniformity and surface quality of the electro-spun chips. Image analysis software was used to quantify the surface quality of the chips in different areas and under different conditions. In addition, EDX spectroscopy was performed to identify the elements of deposited polymer on the microchips.
