Covalent Modification of MWCNT for Styren-Isopren-Styrene Block Copolymer-Based Nanocomposites

Popis výsledku v původním jazyce

Since their discovery, carbon nanotubes (CNT) have attracted particular attention for their unique structural, mechanical and electrical properties. However, thank to strong van der Waals interactions, CNT tend to aggregate and their not uniform dispersion limits their applications. Functionalization of CNT with long molecules and polymer chains enables suppressing the interactions between CNT and their aggregation. In this work, Nanocyl multiwall carbon nanotubes (MWCNT) were covalently modified in order to achieve better dispersion and their location in one phase of styrene-isoprene-styrene block copolymer (Kraton). The modification is expected to cause significant changes in mechanical and electrical properties of final composite materials.
