The functionalised fillers are characterised by Raman spectroscopy and TGA. The functionalised fillers are dispersed in a PBT-PTMO thermoplastic elastomer matrix via in situ polymerisation. The functionalisation causes a fine filler dispersion right at beginning of nanocomposite manufacturing. The fillers act as nucleating agents for crystallisation and evidences for a grafting from PBT at the surface of the functionalised nanotubes are found. An outstanding reinforcement effect by the functionalised CNTs is confirmed by tensile tests. A new and facile functionalization of carbon nanotubes with 1,4-butanediol is proposed. The modified fillers could improve the mechanical properties of thermoplastic elastomers based on poly(butylene terephthalate co-tetramethylene oxide) multi-block copolymers. The nice dispersion and strong interfacial adhesion led to improved mechanical performance. Thermal analysis evidences the chemical coupling of poly(butylene terephthalate) at the functionalized nanoparticles surface. © 2013 WILEY-VCH Verlag GmbH & Co.
