Elaboration and mechanical characterization of nanocomposites thin films

Relationship between structure and rheological, mechanical and thermal properties of polylactide/Cloisite 30B nanocomposites

“…31 Mechanical properties of poly(methylmethacrylate)-SiO 2 thin films have been studied using nanoindentation technique. 32 An improvement in modulus and hardness has been observed with the increase of the indentation depth, in good agreement with the composition of the layers. Last, we have shown a significant improvement into modulus and hardness with the increase of clay loading because of the addition of stiff clay nanofillers into the poly(3-hydroxybutyrateco-3-hydroxyvalerate) matrix.…”

Structure and nanomechanical properties of CdTe thin films

“…The substrate indentation hardness and modulus were determined separately by carrying out experiments on an uncoated substrate and values of H = 8.1 ± 0.4 GPa and E = 79.6 ± 2 GPa were found. These values are in good agreement with the reported data from the literature (Mammeri et al, 2006). As can be seen, the hardness and modulus values of the substrates are much higher than those of the CdTe films and therefore may influence the thin film mechanical properties.…”

“…As can be seen, the hardness and modulus values of the substrates are much higher than those of the CdTe films and therefore may influence the thin film mechanical properties. Previous studies (Saha and Nix, 2002;Simunkova et al, 2003;Mammeri et al, 2006) also indicated that the substrate significantly affects the coating hardness and elastic modulus after a critical depth. This effect may be more important in the case of hard films grown on harder substrates (Saha and Nix, 2002; Simunkova et al, 2003).…”

Mechanical properties of electrochemically synthesised metal–organic framework thin films

“…[29][30][31][32][33] Furthermore, nanoscratch experiments can provide insight into the attachment strength of the lm to the substrate, by determining the applied force needed for delamination. 32 …”
