Purpose – This paper aims to investigate effects of acrylic functionalisation of multiwalled carbon nanotubes (MWCNTs) on properties of carbon
nanotubes/epoxy nanocomposites.
Design/methodology/approach – A number of analytical techniques, including Fourier transform infrared spectroscopy, Raman spectroscopy,
scanning electron microscopy and transmission electron microscopy, were used to assess the effects of acid treatment on MWCNTs.
Ultraviolet-curable coatings were fabricated by sonication and cast moulding process. The mechanical properties of MWCNTs/epoxy composites at
different weight fractions were evaluated by performing tensile tests and dynamic mechanical analysis tests. Also, gel contents were examined.
Findings – It was found that addition of nanotubes monomer to epoxy formulations had significant effect on the viscoelastic and mechanical
properties.
Practical implications – Improving dispersion and alignment of MWCNTs in the composite matrix will contribute to the development of
resin/MWCNTs nanocomposites and promote the applications.
Originality/value – The paper establishes a method to introduce MWCNTs into epoxy matrix as a monomer to enhance the photo curable and
dispersion properties of the MWCNT/epoxy films.
