Roles of aqueous nonsolvents influencing the dynamic stability of poly-(n-butyl methacrylate) thin films at biologically relevant temperatures

Abstract

Poly-(n-butyl methacrylate) (PnBMA) is an important polymer in biomedical applications. Here we study the stability of PnBMA thin films prepared on top of slippery silicon substrates and exposed to nonsolvent...

Advancements in Novel Mechano-Rheological Probes for Studying Glassy Dynamics in Nanoconfined Thin Polymer Films

“…Thus, the addition of plasticizer resulted in a reduction in modulus and viscosity but enhanced σ rec . Later, Sarkar et al showed that incubation of the polymer film in nonsolvents can also affect the stability of the film.…”

“…Thus, the addition of plasticizer resulted in a reduction in modulus and viscosity but enhanced σ rec . Later, Sarkar et al 268 showed that incubation of the polymer film in nonsolvents can also affect the stability of the film. Dewetting as a characterization technique has been explored very well in literature to establish it as a nanorheology tool.…”

“…337 The exact implication of water as a supporting medium needs to be studied more. Sarkar et al 268 using the dewetting experiments showed how incubating in water can affect the stability of thin PNBMA films by affecting the viscosity, modulus, and surface tension of the films. in addition, Galuska et al 338 have shown that there is water uptake in the film on experimenting with Film Over Water (FOW) mode.…”
