Abstract
Economy in our society demands for positive profits. We have implemented all the aspects of capitalism in nowadays way of life, which stands for hard work, that pays off. The idea seems very reasonable, however, it brings a number of environmental concerns to the table after being followed for a number of years. Today, we are very concerned with the issues of global warming and scarcity of clean water sources. One of the contributors to the green house effect is carbon dioxide gas emerging from the utilization of oil-based sources of energy. Most of the industries run on oil-based derivatives. Most of the chemical industry is based on the oil-based polymers, which are not biodegradable or biocompatible. Therefore, discovering alternative substitutes for the oil based polymers through biodegradable and biocompatible materials are a step in the right direction. In this study I have explored the piezoelectric nature of natural biopolymers like chitin, collagen and gelatin. Moreover, I have applied three post-processing techniques to compare the strength of piezoelectric response in chitin Nano-fibers under different post - processing conditions. Using PFM experiment helped reinforce the strength of piezoelectric response in chitin aligned and random fibers. Furthermore, this study served as a steppingstone for discovery of material tensile properties, and finer mats morphology and fiber properties like diameter, porosity and distribution. Comparing material content under different post - processing conditions helped reinforce chemical stability and reactivity. For the future development this project will be focused on conducting a more deliberate study of the tensile properties of the samples. It will also conduct XRD studies, which will shed light on the dependence of piezoelectric and tensile properties on the crystalline structure of chitin Nano-fibers. Moreover, there is potential for conducting porosity experiments. As a result of this work, I have gained an in-depth understanding of mechanical properties of a wide range of biopolymer fibrous mats and their potential applications. Discovery of this scientific avenue is a tremendous potential for a major change in industrial vision and industrial material sourcing strategies.
