摘要: Calorimetry is an effective analytical tool to characterize the glass transition under confinement. The step in heat capacity at dynamic nanometer thin films can effectively be measured with low addenda chip calorimeters. Since AC-calorimetry measures a compliance \(({C}_{p})\) linear response regime it probes molecular dynamics super-cooled liquid state. Down few nanometers of film thickness, always reveals bulk vicinity transition. This different from experiments probing glassy state where liquid-like layers surface or free volume diffusion may influence observed behavior. Temperature modulated offers broad range. Today 11 orders magnitude frequency are covered for samples by combining various kinds range, akin broadband dielectric spectroscopy, significantly important study confinement effects. Varying allows change corresponding length scale probed segmental dynamics. In relaxation map, again, behavior all investigated down thickness.
