Abstract
Abstract Nanocomposites of phenoxy resin with various functionalized multi-walled carbon nanotubes (CNTs) were investigated to assess and compare the effect of functionalization on dynamic mechanical properties. Non-functionalized and various functionalized CNTs containing -COOH, -OH, and -NH2 groups were utilized for preparing phenoxy/CNT nanocomposites through a melt mixing process. Dynamic mechanical properties of nanocomposites, storage modulus (E′), and loss tangent (tanδ) data in temperature range of 20–120°C were collected. Transmission electron microscopy and optical microscopy were also used to gain an insight into the CNTs dispersion state within phenoxy matrix. The functionalized CNTs had no adverse effect on storage modulus of phenoxy. The morphological investigation revealed the highest degree of agglomeration and the shortest tube lengths for the CNT-COOH within phenoxy matrix.
