| Abstract | ||||
| The water industry needs to develop economical and stable materials and methods for providing adequate quantities of fresh water. Cellulose acetate material is widely used in many important applications. The motivation lies not only in the economic and ecological advantages of using cellulose-based materials but also in the advantageous characteristics and properties of these materials. This project aims to provide a better understanding of process-structure-property relationships with advanced functionalities in a new modification of cellulose acetate and to show potential large-scale processability. An important expected result for composite-based cellulose acetate materials is the favorable combination of excellent mechanical properties. The possible applications of the modified cellulose acetate membrane for removing various contaminations from polluted waters will be investigated. To achieve this goal, the main tasks of the research project this year are the synthesis and modification of cellulose acetate and in situ preparation of some nanoparticles and their characterization. In this concept, cellulose acetate was synthesized via acetylation of cotton west and characterized using XRD and FT-IR. The prepared cellulose derivative was subjected to chemical modification to create silicones moieties in its structure, then the new composite was used for in situ preparation of some nanoparticles. The nanoparticles (silver, zinc, zirconium, titanium, and silica) were successfully prepared and characterized using TEM, SEM, and XRD. The next step of the project will be the production of membranes and ex situ preparation of nanoparticles then mixed with the modified cellulose acetate and the production of another type of membrane. | ||||
