Abstract:	本研究主要是利用水性PU與奈米SiO2製備出奈米複合物，並探討其複合物的物性變化及透濕防水性能，以提升水性PU的應用價值，經由實驗結果發現，此複合材料中的奈米無機物可提高整體材料之耐水性、熱性質及機械性質。隨著SiO2的含量增加，其水性PU/二氧化矽複合材料的熔點呈明顯上升趨勢，最高可增加達22.75℃，而熱裂解溫度也因奈米SiO2的複合添加，使耐熱裂解性一併地被提升，最高可達61.86℃。另外，水性PU奈米複合物的加工織物之透濕性雖呈小幅下降，但耐水壓卻有顯著的上升且斷裂強力也隨之提升。 In this study, the nanocomposites were prepared by waterborne PU and nanomgrade SiO2, improved the end-ues Value. The effect of nanograde SiO2 additive on physical properties and vapor permeability and water resistance of nano-composite were researched. Although the thermal properties of the nonacomposites were tested by thermogravimetric analyzer (TGA) and Differential Scanning Calorimeter (DSC). Form results showed that the melt and degradation temperature of nanocomposites increased with increasing nanograde SiO2 Partides, and the Water resistance was the same results, but vapor permeability of nanocomposite film was decreased.
