The properties of a thin polymer film can be significantly affected by the presence of a
penetrant. This can have potential implications for many technological applications, such as …

Literature data on the solubility and diffusivity of CO 2 and N 2, as well as swelling of
polymers in these fluids are reviewed along with experimental methods and modeling. The …

This Perspective provides a critical analysis of the current knowledge concerning solvent
vapor annealing (SVA) of block polymer thin films. Herein, we identify key challenges that …

The application of membranes in gas separation and pervaporation requires materials that
are resistant to plasticizing feed streams. We demonstrate the relationship between CO2 …

A novel high-pressure apparatus and technique were developed to measure
CO2/water/solid contact angles (θ) in situ for pressures up to 204 bar. For two glass …

We examine the contact angle of water droplets on polystyrene (PS) thin films of varying
thicknesses supported by silicon wafers under both air and pressurized carbon dioxide …

The effects of CO2 annealing on the melting and subsequent melt crystallization processes
of spin-cast poly (ethylene oxide)(PEO) ultrathin films (20–100 nm in thickness) prepared on …

We report a mobility gradient of polymer chains in close proximity of a planar solid substrate
in compressed carbon dioxide (CO2) gas. A series of bilayers composed of bottom …

In situ neutron reflectivity was used to investigate the effects of density fluctuations on the
solubility of supercritical carbon dioxide (scCO2) in polymer thin films. Deuterated …

After more than 2 decades of intense research, the density variation in confined polymer
films still remains a puzzling problem subject to controversy as the methods utilized to …
