Poly (4-methyl-1-pentene) (PMP) is a high-performance polymer that exhibits excellent thermal and chemical stability. In this research project, we aim to prepare PMP hollow fiber membranes and investigate their structure and properties.Objectives:The main objective of this project is to prepare PMP hollow fiber membranes and evaluate their properties. The specific objectives are:1. To prepare PMP polymer solution with suitable concentration and additives.2. To fabricate PMP hollow fiber membranes using the wet spinning technique.3. To investigate the morphology and structure of the PMP hollow fiber membranes using scanning electron microscopy (SEM).4. To evaluate the performance of the PMP hollow fiber membranes in terms of water flux, rejection, and stability.Methodology:The following steps will be undertaken to achieve the research objectives:1. Preparation of PMP polymer solution: PMP will be dissolved in a suitable solvent with the addition of suitable additives to obtain a homogeneous solution.2. Fabrication of PMP hollow fiber membranes: The prepared polymer solution will be extruded through a spinneret to form hollow fibers, which will be quenched in a coagulation bath to solidify the polymer. The resulting membranes will be washed and dried.精品文档---下载后可任意编辑3. Characterization of membrane morphology and structure: Scanning electron microscopy (SEM) will be used to investigate the morphology and structure of the fabricated PMP hollow fiber membranes.4. Evaluation of membrane performance: The performance of the PMP hollow fiber membranes will be evaluated in terms of water flux, rejection, and stability. The flux and rejection will be determined by passing water through the membrane and measuring the permeate quality and quantity. The stability of the membrane will be evaluated by measuring its performance over time.Expected outcomes:The expected outcomes of this research project are:1. Preparation of PMP hollow fiber membranes with suitable properties for separation applications.2. Investigation of the morphology and structure of the PMP hollow fiber membranes.3. Evaluation of the performance of the PMP hollow fiber membranes in terms of water flux, rejection, and stability.4. Understanding of the relationship between the structure and properties of the PMP hollow fiber membranes.Conclusion:This research project aims to prepare PMP hollow fiber membranes and investigate their structure and properties. The outcomes of this study will contribute to the development of high-performance hollow fiber membranes for use in various separation processes.
