We present a brief overview of our recent application of the well known phenomenon of buckling instabilities under compressive stresses for measuring mechanical properties of complex polymer nanocomposites. After initial studies of homogeneous nanoscale LbL polymer films we expanded our studies toward more complex materials: polymer nanoscale LbL films reinforced with gold nanoparticles, polymer nanoscale films reinforced with random and oriented silver nanowires, micropatterned bi-component polymer films, sculptured films with 3D topology, and biomaterials (silk).
