| Summary: | 碩士 === 國立雲林科技大學 === 化學工程與材料工程系 === 103 === The purpose of this study was to use of three different properties of the polymer materials(1)Poly(methyl-methacrylate),referred to as PMMA,(2)Carboxymethyl-β-cyclodextrin, referred to as CM- β-CD and (3) Chitosan, referred to as CS, solvent selection formic acid can be formulated PMMA / CM – β – CD / Chitosan solution, and it can produce nanoscale fibers for application by electrospinning .
At first, the basic properties of the PMMA / CM – β – CD / Chitosan solution was observed with conductivity meter, observed with increasing PMMA content, and found the trend of decrease in conductivity of the solution. The electrospinning conditions of manufacturing (including: the flow rate of the propeller, the needle distance, voltage, ambient temperature and the fiber collection methods, etc ...) to the effect of different ratios of PMMA / CM – β – CD / Chitosan nanoscale fibers. The best conditions of manufacturing were the output voltage of 23kv, solution flow rate 0.030 ml/min, collection fiber distance of 15 cm and ambient temperature 30℃. The ratio of the best composite of polymer solution were dvided into three groups to produce nanoscale fibers, and prepared individually for different applications(1) Fiber barbed wire (2) Semi-finished fiber masks (3) Antibacterial fiber fabrics.
The physical analysis are using field electron microscope (FE-SEM), Fourier transform infrared spectroscopy (FTIR), the contact angle measuring instrument (CA), X-ray diffraction analyzer (XRD) and nitrogen isothermal adsorption / desorption analyzer (BET) detection surface patterns fibers, functional groups, hydrophobicity, crystallinity analysis, hole size distribution and specific surface area and void volume.
Finally, the results show that (1) Fiber barbed wire: the maximum amount of adsorption qemax = 124.90mg/g for the proposed second-order kinetic adsorption model, and the material has a mesoporous structure were encapulsated the heavy metal copper ions to achieve the effect of adsorption . Thus, it also has an internal diffusion model. (2) Semi-finished fiber masks: conform to disposable dust masks D1 grade and the same time both medical masks - bacterial filter function. (3) Antibacterial fiber fabrics: Medical antibacterial AATCC 100 test results prove that fiber is an antimicrobial can be applied to the fabric of the medical aspect.
