“…The effect of ultrasonic fields on the dilution of PMMA in the solvents has been studied for PMMA films obtained by the drop-casting method. The ultrasonic vibration decreases the amount of residual solvent in the film to one-twelfth of the value, which occurs by spontaneous evaporation [18]. Other studies focused on the effect of dimethyl formamide and tetrahydrofuran (THF) on the miscibility in the liquid phase between PMMA and polyvinyl chloride at different relative concentrations [12] and the effect of solvents on the morphology of films prepared by either laser evaporation [16] or drop-casting [19].…”

The physical, thermal, structural, and mechanical properties of poly(methyl methacrylate) PMMA foils cast from solutions of toluene were investigated by differential scanning calorimetry, optical microscope, Fourier infrared spectroscopy, and dynamical mechanical analysis. The PMMA foils were prepared from a different ratio of PMMA powder with toluene solvent by the solution cast method. The surface features, glass transition temperature, and C-H bonds of foils were investigated and compared with commercial PMMA foil. The mechanical characterization of foils was examined by using static and dynamic loads in axial and transverse modes. The tensile behaviors of the commercial and as-prepared foils were investigated by using a strain rate of 0.01/s. The dynamical behavior of the foils was tested in tensile mode using 0.1 N of stress with a frequency of 1 Hz for the determination of storage, loss modulus, and damping values of the tan delta. A significant shape memory was observed in all of the prepared PMMA foils. The solution cast method allows for tuning the glass transition temperature of polymer foil that could easily integrate with the NiTi alloy phase transition temperature to fabricate a suitable composite structure. Integrating both structures will open the flexibility in bistable actuators in composite structures as a function of thermal cycles.

“…The Huggins' co‐efficient [ K H ], experimental and theoretical intrinsic viscosity [η], Δ B , Δ K , and interaction parameters such as Δ[η] m , µ, α, and β are used to assess the miscibility behavior of the polymers. Huggins' coefficient ( K H ) is calculated using the relation;

K_{H} = slope of the curve (η_{s p} / c \sim c) / {[η]}^{2}

where η sp is specific viscosity and [η] is intrinsic viscosity.…”

The parent repeating sequence of elastin, poly(GVGVP) has been synthesized by solution phase method and characterized by 13C and 1 H-NMR spectroscopy. The poly(GVGVP) and poly(vinyl pyrrolidone) (PVP) interactions have been examined in solution phase by the viscometric method at 24 C. The interaction parameters such as α, β, μ, and Δ[η] m indicated the miscible nature of poly(GVGVP)/PVP blends. Immiscibility occurred when the quantity of poly(GVGVP) is lesser than 60%. In the solid phase, Fourier transform infrared spectroscopic scrutiny of the thin films of poly(GVGVP)/PVP blends indicated the presence of strong intermolecular interaction such as hydrogen bonds linking the blend components. This result was further supported by glass transition temperature (T g ), scanning electron microscopic, and X-ray diffraction studies. The blending of poly(GVGVP) with PVP may provide an opportunity to produce new materials for potential biomedical applications.

The parent repeating sequence of elastin, poly(GVGVP), was synthesized using solution phase method and characterized by 13C‐ and 1H‐NMR spectroscopy. In order to study the polymer–polymer interactions between poly(GVGVP) and hydroxyl propyl methyl cellulose (HPMC), the blends were prepared both in aqueous and solid phase and examined using various analytical techniques. The viscometric measurements have been carried out at 24 °C and the interaction parameters such as α, β, µ, and Δ[η]m revealed the miscible nature of the poly(GVGVP)/HPMC blend systems. In addition, Fourier‐transform infrared spectroscopy showed the formation of strong intermolecular hydrogen bond between poly(GVGVP) and HPMC networks. This result was further supported by glass transition temperature (Tg), scanning electron microscopic, and X‐ray diffraction studies. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.
