The cure behavior and the modular change of the nanocomposite were monitored with the resin curemeter. The results showed that after the intercalation of montmorillonite, the nanocomposite cure faster and the modulus of compound increased obviously. Especially, the elasticity and fitness of the PDMS/MMT nanocomposite were enhanced, also the nanocomposite had better mechanical properties and stronger solvent resistance. The results suggest that this nanocomposites is more suitable for preparing elastomeric stamps in soft lithography.展开更多
