本研究以奈米碳化鋯 (ZrC) 粒子與PU 混合後，以羅拉進
行特定壓力與時間之捻壓，然後製成薄膜。結果發現，以此種方法
所製備之複合材料之薄膜，其強度、彈性係數、破斷能、軟鏈結之
熔點、軟鏈結之玻璃轉位點及焦碳形成之百分比等均隨複合薄膜材
料中奈米碳化鋯粒子其使用量之增加而提高，但達2.5%之使用量
後反而會降低；而伸度及焦碳之形成溫度則與前者呈現相反之變
化，唯在奈米碳化鋯之使用量達2.5%後，其趨勢則與前者相同。
若奈米碳化鋯/PU 複合材之薄膜其製備過程未經捻壓，則不論奈米
碳化鋯使用量之多寡，薄膜樣本之物性均隨奈米碳化鋯使用量之增
加而降低。經以FTIR 與廣角繞射分析後證實，在複合薄膜材料製
備之前，先以羅拉捻壓ZrC/PU 混合物，所得製得之薄膜其上之PU
分子可以醚及酯基與奈米碳化鋯相互作用，形成配位結合，改變物
性、結晶構造與熱性質。

In this study, we used nanometer zirconium carbon (ZrC)
particle to compose with polyurethane resin under a specific roller
pressure and time period to prepare the composite films, and find that
the values of tensile strength, modulus, energy at break, Tm of
soft-segment, and Tg of soft-segment, and weight percentage of char
yield are increased, and elongation and char yield temperature are
decreased with the increase of the amount of nanometer zirconium
carbon particle composed in polyurethane as the amount of particle is
lower than 2.5 wt%, but those data are decreased with the increasing
of the particle used as the amount of particle is higher than 2.5 wt%.
However, those data of the different physical properties are all
decreased with the increasing of the amount of nanometer zirconium
carbon particle used without roller pressure. From infrared
spectroscopic spectra and Wide Angle X-Ray Diffraction patterns, we can
assure that the ether and ester groups of polyurethane polymer can
interact with nanometer zirconium carbon with coordinate bonding to
change the structure of crystal, thermal properties and physical
properties of polyurethane polymer/nanometer zirconium carbon
particle composites films under roller pressure before preparation.
