碩士 === 國立臺北科技大學 === 有機高分子研究所 === 99 === This study is synthesized Polyurethane by prepolymer synthesis. Hard segment is made by 1,4-butane diols and 4, 4’-diphenylmethane diisocyanate, and soft segment is made by polytetramethylene glycol. Furthermore, added the ZnO powders to N,N-dimethyl acetamide, then mixed with PU during synthesis process. Finally, through the drying treatment in 60℃, and fabricate PU/ZnO composite materials.PET and PA 6 fabrics were treated by plasma in different seconds, and pick up with ZnO/PU and drying treatment to fabricate the composite materials. From the experimental results, The contact angle would be improved to 0° that proved the hydrophilic properties could be modified. The useful function group would be checked by FT-IR spectrum that proved the functional group has not existed significantly. Otherwise, the UV-vis properties of the composites were also tested to investigate UV penetration coefficient and also found improvement close to 0%. It could used at umbrellas、hat and kind of Shade cloth.
