Study of the mechanical response of carbon nanotubes-SU8 composites by nanoindentation

Multiwalled carbon nanotubes (MWCNTs)/SU8 composites have been produced to enhance the mechanical properties of SU8 photoresist. We have studied the influence of SU8 solvent on the structural homogeneity of composites through nano-indentation testing. It is found that acetone and propylene glycol methyl ether acetate (PGMEA) are very suitable solvents to prepare MWCNTs/SU8 composites with significant increase of the Young's modulus (E-Y). The highest increase of E-Y in respect to the parent material of 104% was obtained with acetone as solvent. It was noticed that the remaining solvent in the composite influences strongly E-Y, as well. (C) 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
