Elastic Moduli of Ultrathin Amorphous Polymer Films
The elastic moduli of ultrathin poly(styrene) (PS) and poly(methylmethacrylate) (PMMA) films of thickness ranging from 200 nm to 5 nm were investigated using a buckling-based metrology. Below 40 nm, the apparent modulus of the PS and PMMA films decreases dramatically, with an order of magnitude decrease compared to bulk values for the thinnest films measured. We can account for the observed dec...
متن کاملTemperature- and thickness-dependent elastic moduli of polymer thin films
The mechanical properties of polymer ultrathin films are usually different from those of their counterparts in bulk. Understanding the effect of thickness on the mechanical properties of these films is crucial for their applications. However, it is a great challenge to measure their elastic modulus experimentally with in situ heating. In this study, a thermodynamic model for temperature- (T) an...
متن کاملElastic Moduli of Polymer Thin Films: A High-throughput Metrology
Thin polymer films are playing an increasing role in technological applications such as lithographic resist layers, barrier layers, electronic packaging, and optical coatings. As a result, it is becoming apparent that confined polymers can display subtle or even dramatic differences in their physical properties when compared to the same polymers in the bulk state. Understanding these difference...
متن کاملWrinkling of Ultrathin Polymer Films
This paper presents a bilayer model to account for surface effects on the wrinkling of ultrathin polymer films. Assuming a surface layer of finite thickness, effects of surface properties on the critical strain, the equilibrium wavelength, and the wrinkle amplitude are discussed in comparison with conventional analysis. Experimental measurements of wrinkling in polymer films with thickness rang...
متن کاملElastic moduli of nanostructured carbon films
We have computed the elastic constants of nanostructured carbon films as obtained from classical molecular dynamics simulations of a cluster beam deposition process. The calculations show that the elastic constants of the deposited films are related to the average size of the clusters by a power law. This allows us to extrapolate the present theoretical data to the scale of the experimental res...
