Mechanical Performance of Diamine Silane Modified Carbon Nanotubes Reinforced Epoxy Resin Composites
Source abstract
Abstract
The addition of unmodified carbon nanotubes (CNTs) to epoxy resin will cause a decrease in the initial thermal decomposition temperature of the EP/CNT composite material, likely due to the weak interfacial adhesion between the nanofiller and its surrounding matrix. As such, functionalized drug carriers using CNTs could overcome this; for example, after silane modification, the diameter of CNTs is increased from 32 nm to 38 nm. The fracture cross-section of EP/CNT composite material is rough on the surface and exhibits ductile fracture, while the pure EP material presents a brittle fracture cross-section with a smooth fracture cross-section. It has also been proven that the dispersibility of CNTs is improved, along with an enhancement in the degree of dispersion. Thus, as compared to pure EP, after surface treatment of the CNTs, the tensile strength and elastic modulus of the EP/CNT composite material were improved up to a value of 134.6% and 32.9%, respectively, while the elongation at break decreased to 60.09%.
