Special Issue Information

Dear Colleagues,

Functional polymer composites are present trends in the sector of biomedical, biosensor, actuators, and biotechnological applications; this is because polymer-based composites are light, cheap, versatile, and durable materials under aggressive environmental conditions. Moreover, they constitute a step in the direction of smart polymer composites, with their versatile behavior permitting a variety of applications in commercial markets of the energy harvesting, energy storage, and self-sensing sectors. Integrating the functional behavior of polymers and substrates could impact the movement towards the application of composites in multiple sectors, from macro- to micro-scale applications. For this Special Issue, the title “Functional Polymer Composites: Latest Advances and Prospects” has been proposed. A wide variety of chosen fillers and matrixes could have the characteristics to meet the complex standards for functional polymer composite materials in high-tech industries. Functional polymer composites are crucial in the development of new, innovative technologies. Advances in functional polymer composites promote new solutions concerning materials related to energy and environmental policies. The mechanical performance of smart polymer composites could exhibit better performance in lightweight energy storage systems with the development of improved multifunctional and non-corrosive characteristics.

The Special Issue aims to collect articles reporting on the latest advances and prospects in this field, presenting the methods, designs, properties, and structures characterizing promising new applications for functional polymer composites. The Special Issue covers potential applications in various areas, including energy storage, energy harvesting, energy devices, electricity, shape memory materials, actuators, and sensor areas. Papers presenting advanced modelling, simulation, and experimental processes—covering the design, preparation, and prediction of the properties of proposed functional polymer composites—are warmly welcomed for submission to this Special Issue.

Physical, Thermal, and Mechanical Characterization of PMMA Foils Fabricated by Solution Casting

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. Full article

Changes in the physicochemical characteristics of a regenerated cellulose (RC) film due to a surface modification with room-temperature ionic liquids (ILs) are determined. Two ILs (1-butyl-3-metylimidazolium hexafluorophosphate and tricaprylmethylammonium chloride) were selected, and film surface modification was performed by a dip-coating process (1 h) in the corresponding IL. The surface characterization of the RC/IL films was carried out by XPS at various take-off angles (from 15° to 75°), while the modification of mechanical properties was established by tensile analysis, obtaining a significant increase for the Young modulus of both RC/IL films when compared with the RC-support. Optical characteristics of the RC/IL films were determined by transmittance and reflectance measurements for wavelengths covering visible and near-infrared regions, while impedance spectroscopy (IS) measurements allow us to estimate the electrical changes in the RC/IL films. These results show the high transmittance of both RC/IL films (>90%) with slight differences depending on the IL in both optical regions, while the IS data analysis indicated a conductivity reduction and dielectric constant increase in the dielectric constant for both eco-friendly RC/IL films.

Antibiotics are increasingly used to treat certain bacteria that are harmful to humans. However, their inadequate or excessive use can lead to the proliferation of certain more resistant strains, which ultimately reduces their effectiveness. To counter this, it is essential to limit the amount of antibiotics ingested, particularly through animal food, if the animals themselves have received antibiotic treatment. In the case of milk, it is necessary to be able to detect quantities of antibiotics in the range of a few parts per billion. A sensor has therefore been developed for this purpose. The sensitive layer that we propose to use in this study, is based on a molecularly imprinted conductive polymer (MICP) that allows a very specific interaction and have been integrated into electrochemical detection approaches by polymerization on electrodes. The sensor is based on the measurement of the variation in conductivity of a sensitive layer deposited between two electrodes, which is influenced by the presence of the antibiotic. Although it seems possible to further improve the performance of these sensors, their use in this field seems very promising considering the obtained results. Full article
