“…1556 and 1650 cm-1 were showed the vibrational mode of amide groups, the two sharp peaks at 1039 and 1221 cm-1 were observed for the S-O stretching of sulfonate groups, and the band around 3400 -3000 cm-1owing to the O-H stretching vibration [12,13]. In the IONPs spectrum, the broad band at 3700-3000 cm−1 indicated the stretching vibration mode of surface hydroxyl groups of the pristine IONPs [20].…”

“…Figure 4 shows the Thermo Gravimetric Analysis (TGA) curves of PVA, PAMPS, IONPs and PVA/PAMPS/IONP composite. The mass loss of the PVA occurred in two stages: The first mass loss around100-150°C was attributable to the loss of water molecules and the second mass loss around 250-350°C owing to the thermal degradation of the PVA backbone [12,13]. In the PAMPS, the decomposition temperature occurred at 100°C due to moisture loss, and around 300°C was the decomposition of sulfonate and propenyl groups.…”

“…Recently, chemically cross-linked poly (vinyl alcohol) and poly (2-acrylamido-2-methyl-1-propanesulfonic acid) (PVA-PAMPS) films are effectively used in the mechanical devices, attributable to their biocompatibility and cost-effectiveness [12,13]. Notably, the PVA has been widely utilized in the fabrication of tablet coating, artificial tears, drug delivery and tissue replacement, owing to their specific characteristics of toxicologically safe, high oxygen permeability and biodegradability [14], conversely they possess very less mechanical stability.…”

“…Specifically, the PAMPS, a sulfonic acid acrylic monomer has high proton conductivity and well hydrated due to presence of sulfonic acid groups in its backbone, and they are effectively applied infuel cells, medical devices and actuators [7,15]. In order to improve their mechanical and thermal stabilities of these PVA and PAMPS polymers, they could be blended / chemically crosslinked for obtaining flexible, mechanically and thermally stable material [12,13]. Generally, the reinforcement of nano-particles into the polymer matrix enhances the mechanical, dimensional and thermal stabilities of the host polymer matrix.…”

“…It can be elucidated by the interaction of the hydrophilic IONPs and the hydrophilic PVA/PAMPS matrix with the water molecules [12,13]. The water content of the PVA/PAMPS (66.06 %), PVA/PAMPS/IONP-1 (68.58 %), PVA/PAMPS/IONP -2 (70.13 %), PVA/PAMPS/IONP -3 (71.23%) and PVA/PAMPS/IONP -4 (73.83 %) were observed.…”

Open Access Research Articlepolymeric materialsin order to enhance their applications as well as physico-chemical properties of the host polymer [10,11].Recently, chemically cross-linked poly (vinyl alcohol) and poly (2-acrylamido-2-methyl-1-propanesulfonic acid) (PVA-PAMPS) films are effectively used in the mechanical devices, attributable to their biocompatibility and cost-effectiveness [12,13]. Notably, the PVA has been widely utilized in the fabrication of tablet coating, artificial tears, drug delivery and tissue replacement, owing to their specific characteristics of toxicologically safe, high oxygen permeability and biodegradability [14], conversely they possess very less mechanical stability. To overcome this major drawback, it should be chemically cross-linked / blended with other hydrophilic materials to acquire mechanically stable materials. Specifically, the PAMPS, a sulfonic acid acrylic monomer has high proton conductivity and well hydrated due to presence of sulfonic acid groups in its backbone, and they are effectively applied infuel cells, medical devices and actuators [7,15]. In order to improve their mechanical and thermal stabilities of these PVA and PAMPS polymers, they could be blended / chemically crosslinked for obtaining flexible, mechanically and thermally stable material [12,13]. Generally, the reinforcement of nano-particles into the polymer matrix enhances the mechanical, dimensional and thermal stabilities of the host polymer matrix. Very recently, Guo et al. [16] fabricated IONPs reinforced PVA composites with superior thermal stability, and the IONPs have robust interaction with the PVA matrices by hydrogen bonding between their hydroxyl groups.In this study, based on the above merits of IONPs in the polymer matrix, PVA/PAMPS / IONPs nano-composite films were fabricated by Thermally Induced Phase Separation technique. The major function of the IONPs is to enhance the thermomechanical properties, magnetic activity (superparamagtic) and dimensional stabilities of the PVA/PAMPS matrix. The physicothermal properties of the PVA/PAMPS/IONPs films were studied AbstractThe aim of this study is to investigate the influence of Iron oxidenano-particles (IONPs) on the physico-chemical properties of poly(vinyl alcohol) (PVA) -poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPS) polymer matrix. The IONPs were synthesized from ferric chloride using NaBH 4 as reducing agent in distilled water, and the IONPs were characterized by FT-IR and TGA. Thinnano-composite films were fabricated by blending IONPs colloidal suspension with PVA / PAMPS solution by Thermally Induced Phase Separation technique. The reinforcement of the IONPs in the PVA / PAMPS matrix was also confirmed by FT-IR and TGA, and water uptake measurements revealed the hydrophilic nature of the IONPs. The cross-sectional and surface morphologies of the films were analyzed by High-Resolution Scanning Electron Microscopy, and the results showed that the surface roughness of the films and size of the IONPs enhanced with respect to t...

The study of proton conductivity processes has gained intensive attention in the past decades due to their potential applications in chemical sensors, electrochemical devices, and energy generation. The scientific community has focused its efforts on the development of high‐performing polymeric membranes as proton exchange membranes (PEMs) for fuel cell (FC) applications. In particular, high conductivity at different humidity and temperature and enhanced chemical and mechanical stability under operative conditions are considered the main goals to be reached. The design of mixed‐matrix membranes (MMMs) based on conductive polymers and inorganic fillers is an approach commonly used for achieving materials with improved conductive and mechanical properties. In the last five years, the use of metal‐organic frameworks (MOFs) as fillers for conductive MMMs has rapidly grown for their intrinsic stability and structural versatility. The recent progress around the proton conductivity of MOF based composite membranes on PEMs for FC applications is critically reviewed.

devices to work under tough conditions. There are reports about artificial ATP synthesis and biomimetic power generation through proton gradients. [3] These abiotic ones have potential applications for electronic devices, fuel cell, and chemical sensors. [4] However, significant challenges remain for developing high performance and dynamic regulation of proton conduction. A class of material that is possibly able to improve the proton conduction performance in fuel cells is metal-organic frameworks (MOFs). [5] MOFs are organicinorganic composite porous materials, constructed from metal ions or clusters, and organic ligands through coordination bonds. [6] MOFs have such advantages as high porosity, large specific surface area, and enormous chemical variety. [7]
