“…Pure salbutamol particles showed the highest tendency to absorb water and to retain water after drying. A separate sharp endotherm at ∼60°C, which is in the vicinity of the glasstransition temperature, is attributed to an enthalpy relaxation of amorphous material (5,(43)(44)(45)(46). However, the relaxation peak disappeared upon 5 days drying.…”

“…In the present study, likewise, the small crystalline domains were 'solubilized' by amorphous matrix of the same material. The size-dependent melting of crystals has been intensively studied (20,(43)(44)(45)(46). In general, the melting temperature decreases and the endotherm is lowered and becomes broader as the crystal size decreases to a few tens of nanometres.…”

“…73 Equation (13) has been highly successful in describing T m shifts with geometrical confinement in diverse materials, including polymers. [74][75][76][77][78][79][80] When confinement becomes comparable to 4 − 6 times the molecular size, it is known that Eq. (13) starts to fail, 50 corresponding to the thinnest films we examine.…”

Changes in the dynamics of supported polymer films in comparison to bulk materials involve a complex convolution of effects, such as substrate interactions, roughness, and compliance, in addition to film thickness. We consider molecular dynamics simulations of substrate-supported, coarse-grained polymer films where these parameters are tuned separately to determine how each of these variables influence the molecular dynamics of thin polymer films. We find that all these variables significantly influence the film dynamics, leading to a seemingly intractable degree of complexity in describing these changes. However, by considering how these constraining variables influence string-like collective motion within the film, we show that all our observations can be understood in a unified and quantitative way. More specifically, the string model for glass-forming liquids implies that the changes in the structural relaxation of these films are governed by the changes in the average length of string-like cooperative motions and this model is confirmed under all conditions considered in our simulations. Ultimately, these changes are parameterized in terms of just the activation enthalpy and entropy for molecular organization, which have predictable dependences on substrate properties and film thickness, offering a promising approach for the rational design of film properties.
