層剥離型ポリマー系ナノコンポジットの層剥離状態と物性との関係

抄録

Dennis et al examined in detail the influence of the structure of extruder and screw on the nanocomposite formation of polyamide 6/organically modified montmorillonite (5%).
In this paper, the relation between the degree of delamination of clay and the mechanical properties of nanocomposite is quantitatively clarified, by using the above data.
As the delamination proceeds, the mechanical properties (tensile yield strength and tensile modulus) increase. This tendency is like reverse S-type curve. The relation about impact strength cannot be clarified definitely, but its maximum value may exist at the region of insuffrcient delamination.
