Preparation and Properties of Clay Nanocomposites based on Epoxy/Acrylate Interpenetrating Polymer Network

摘要

Two types of organophilic-montmorillonite (treated with dimehyldioctadecyl anmonium chloride(C38MMT) or amino dodecnic acid chloride(C12MMT)) dispersed into BPN based on epoxy/acrylate have been prepared by simultaneous polymerization techniques. 2-ethyl-4-methylimidazole (2E4MZ) as curing agent for epoxy resin was used, and AIBN or BPO were used for radical initiators of the acrylate, respectvely. The cured products were analyzed by some measurement techniques, such as X-ray diffraction, dynamic mechanical analysis and tensile shear test. In the first case, involving the C38MMT, the intercalated nanocomposite was produced by AIBN-2E4MZ cured system. On other hand, delaminated-nanocomposite was obtained in all other curing systems (using C12MMT system and C38MMT/BPO system). The glass transition temperatures of the both nanocomposites were slightly higher than the un-filled IPNs. The tensile shear strength of the delaminated-nanocomposite was drastically better more than intercalated nanocomposite.
