Topical Collection Information

Dear Colleagues,

The functionalised and modified polymer electrolyte membrane and its composite materials have widely played a significant role in the development of advanced science and technologies in energy storage and conversion devices, biomaterials, optoelectronics, etc. and they are constantly increasing and expanding over every field of technology. Modern polymer technology can enable the precise control of polymer morphology, which satisfies the required performance in high-technology devices. Besides, polymers are complex materials that are useful candidates for sensor and biomedical applications. The polymer composites are alternatives to classical chemicals which consist of high efficiency, precision, and suitability. One of the most significant characters of the polymer composite has reduced stiffness in comparison to the glass fibre, that means that it can be used in a wide range of sensor and biomedical industries. Hence, the latest developments of polymeric materials pave the way to produce an inexpensive and dependable sensor and biomedical systems arranged for industrial application. Furthermore, sustainable polymer technology is expected to reach new scientific fields, as well as the development of existing industries in the future. Thus, we want to highlight the efforts of researchers who have contributed to recent development in various fields based on modern polymer technology as the aims of this Topic Collection.

The topics of interest include, but are not limited to:

  • Synthesis and characterization of conductive polymers.
  • Advanced organic-inorganic composite materials for application to electrochemical devices.
  • Composite materials based on hydrocarbon membranes, including modelling for energy device application.
  • Polymer electrolyte membrane for water electrolysis and fuel cell application.
  • Polymer electrolyte for energy storage and conversion applications.
  • Functional polymer for electrochemical applications.
  • Functionalized polymers for antimicrobial, anticancer and tissue engineering applications.
  • Polymeric materials for sensors applications, including chemosensors, gas sensors, etc.

To produce highly efficient and repeatable perovskite solar cells (PSCs), comprehending interfacial loss and developing approaches to ameliorate interfacial features is essential. Nonradiative recombination at the SnO2–perovskite interface in SnO2-based perovskite solar cells (PSCs) leads to significant potential loss and variability in device performance. To improve the quality of the SnO2 electron transport layer, a novel polymer-doped SnO2 matrix, specifically using polyacrylic acid, was developed. This matrix is formed by spin-coating a SnO2 colloidal solution that includes polymers. The polymer aids in dispersing nanoparticles within the substrate and is evenly distributed in the SnO2 solution. As a result of the polymer addition, the density and wetting properties of the SnO2 layer substantially improved. Subsequently, perovskite-based photovoltaic devices comprising SnO2 and Spiro-OMeTAD layers and using (FAPbI3)0.97(MAPbBr3)0.03 perovskite are constructed. These optimized devices exhibited an increased efficiency of 17.2% when compared to the 15.7% power conversion efficiency of the control device. The incorporation of polymers in the electron transport layer potentially enables even better performance in planar perovskite solar cells. Full article

Bistable morphing composites have shown promising applications in energy harvesting due to their capabilities to change their shape and maintain two different states without any external loading. In this review article, the application of these composites in energy harvesting is discussed. Actuating techniques used to change the shape of a composite structure from one state to another is discussed. Mathematical modeling of the dynamic behavior of these composite structures is explained. Finally, the applications of artificial-intelligence techniques to optimize the design of bistable structures and to predict their response under different actuating schemes are discussed.

The aim of this paper was to provide insight into the impact of matrix and surfactants on the rheology, morphology, and dielectric and piezoelectric properties of screen-printed BaTiO3/PVDF composites. Two matrices were compared (PVDF–HFP and PVDF–TrFE), and lead-free BaTiO3 microparticles were added in volume fractions of 30% and 60%. Here, we demonstrated that the presence of surfactants, helping to prevent phase separation, was crucial for achieving a decent screen-printing process. Fourier-transform infrared (FTIR) spectroscopy together with scanning electron microscopy (SEM) showed that the two “fluoro-benzoic acid” surfactants established stable bonds with BaTiO3 and improved the dispersion homogeneity, while the “fluoro-silane” proved to be ineffective due to it evaporating during the functionalization process. PVDF–TrFE composites featured a more homogeneous composite layer, with fewer flaws and lower roughness, as compared with PVDF–HFP composites, and their inks were characterized by a higher viscosity. The samples were polarized in either AC or DC mode, at two different temperatures (25 °C and 80 °C). The 30% BaTiO3 PVDF–TrFE composites with two fluorinated surfactants featured a higher value of permittivity. The choice of the surfactant did not affect the permittivity of the PVDF–HFP composites. Concerning the d33 piezoelectric coefficient, experimental results pointed out that PVDF–TrFE matrices made it possible to obtain higher values, and that the best results were achieved in the absence of surfactants (or by employing the fluoro-silane). For instance, in the composites with 60% BaTiO3 and polarized at 80 °C, a d33 of 7–8 pC/N was measured, which is higher than the values reported in the literature. Full article
