Description

A wrinkling approach was used to study the mechanics of hybrid nanotube/nanocrystal coatings adhering to soft polymer (PDMS) substrates. We focused on three thicknesses: 10 nm, 30 nm, and 40 nm. The approach we used is the Strain-Induced Elastic Buckling Instability for Mechanical Measurements (SIEBIFMM) technique, which allows measurement of the SWCNT film mechanics by the buckling wavelength and the film thickness by inducing a compressive stress in the films at different strains; 2%, 4%, 6%, 8%, 10%, and 12%. In this thesis, dip-coating method with colloidal nanocrystals was used to enhance the rigidity of the carbon nanotube films by filling the pores of the nanotube network. Our results show an almost two-fold enhancement in the Young modulus of a thin SWCNT film related to the presence of a thin interpenetrating over-layer of the semiconductor nanocrystal.
