title = "Nanomechanical properties of ultrathin polymers",
abstract = "We have developed a novel microbubble inflation method to measure the viscoelastic properties of ultrathin polymer films over a range of stresses and temperatures. The method is capable of measuring the biaxial creep compliance response of films as thin as 13 nm. We summarize some prior experiments that show a dramatic stiffening of both polyvinyl acetate) (PVAc) and polystyrene (PS) in the rubbery regime at the reduced thickness but a material specific degree of reduction in the glass transition temperature. In addition, we show preliminary results of creep recovery experiments and thin film rupture images that suggest that the method can be used for a broader range of mechanical measurements than originally anticipated.",
