ABSTRACT The effects of mixing sequence of the polyether polyol and curing agent (triethylenetetramine) on mechanical and thermal properties and morphology of epoxy/polyether polyol/organoclay ternary nanocomposites are investigated in this study. The polyether polyol domain size data are relatively unchanged with mixing order both in epoxy/polyether polyol blends and in ternary nanocomposites. Generally, impact strength data of the ternary nanocomposites prepared by the second addition order are higher than the ones produced by the first addition order. Flexural strength and strain at break may be accepted as unaltered generally for the ternary nanocomposites with respect to addition order. Except for the sample containing 3 wt-% Cloisite® 30B and 3 wt. % polyether polyol, flexural modulus data are close to each other in ternary nanocomposites. The highest flexural modulus is obtained for the 5 wt-% Cloisite® 30B and 3 wt-% polyether polyol sample prepared by the second addition order, as 2978 ± 27 MPa.

混合顺序对环氧/聚醚多元醇/有机粘土三元纳米复合材料的影响

摘要 本研究研究了聚醚多元醇和固化剂（三亚乙基四胺）的混合顺序对环氧树脂/聚醚多元醇/有机粘土三元纳米复合材料的机械和热性能以及形貌的影响。聚醚多元醇域尺寸数据在环氧/聚醚多元醇共混物和三元纳米复合材料中的混合顺序相对不变。一般情况下，第二次加入制备的三元纳米复合材料的冲击强度数据高于第一次加入制备的三元复合材料。就加成顺序而言，对于三元纳米复合材料而言，弯曲强度和断裂应变通常可以被接受为未改变。除了含有 3 wt-% Cloisite® 30B 和 3 wt. % 聚醚多元醇，弯曲模量数据在三元纳米复合材料中彼此接近。
