An innovative fabrication of compliant, robust, lightweight, nanocomposite membranes with extraordinary sensitivity and dynamic range was reported. It was demonstrated that nanocomposite membranes, with nanoscale thickness and microscopic lateral dimensions, can possess unparalleled sensitivity combined with extreme robustness. Freely suspended, nanocomposite, organic-inorganic membranes using a polymer-nanoparticle SA-LbL technique was fabricated. It was observed that the presence of significant pre-stretching can be suggested as an additional reason for the outstanding micromechanical properties and unusual recovery phenomenon.
