“…A significant change was absent in terms of shifting of the peak, but the intensity of the peak due to enzyme attack was found slightly diffused.4 Furthermore, for the epoxy, the presence of benzene and ester at the OH bond through a sharp broad peak was observed in the range of 3300–3500 cm −1 . [ 44 ] In case of EFS, the combination of both groups is relatively noticeable with the appearance of the same peak as found in both epoxy and RFS. The stretching vibration for PO 4 3− bond of hydroxyapatite in fish scale was observed at 1012 cm −1 .…”

Degradation of epoxy‐based composites reinforced with fish scale particles was studied using two enzymes, papain, and bromelain. Mechanical, structural, thermal, and morphological properties of the composites were characterized. Results showed a significant deterioration of the properties after the degradation of the composites. Flexural strength of the composites was reduced by 38% and 13%, respectively, due to the presence of the enzymes. Crystalline temperature of the composites was significantly decreased by 18°C due to the enzymatic attack. A significant amount of weight loss occurred during the degradation process. In addition, the structural and surface properties of the composites demonstrated the degradation of the polymer and the fish scale. Overall, fish scale can be used as a potential filler to tune the mechanical properties of the polymers and to facilitate the degradation of the polymers.

“…The degradation of the NE and epoxy‐based composites happens in the temperature between 350°C and 600°C. [ 30 ] The residual weight of the NE, E10PC, E20PC, E30PC, E40PC, and E30MPC composites was 3%, 11%, 10%, 27%, 30%, and 28%, respectively. From Table 2, it was found that the T onset temperature of the NE, E10PC, E20PC, E30PC, E40PC, and E30MPC composites was 345°C, 350°C, 350°C, 360°C, 350°C, and 361°C, respectively.…”

“…At around 100 C, the composites go through weight loss due to the moisture and volatile elements absorbed by the composites during the preparation. Then, the dehydration of the composites occurs in between 100 C and 350 C. The degradation of the NE and epoxy-based composites happens in the temperature between 350 C and 600 C. [30] The residual weight of the NE, E10PC, E20PC, E30PC, E40PC, and E30MPC composites was 3%, 11%, 10%, 27%, 30%, and 28%, respectively. From Table 2, it was found that the T onset temperature of the NE, E10PC, E20PC, E30PC, E40PC, and E30MPC composites was 345 C, 350 C, 350 C, 360 C, 350 C, and 361 C, respectively.…”

Different loading of Portland cement (PC) (10, 20, 30, and 40 wt%) was used to produce epoxy-based polymer concrete. The optimum loading was used to prepare another sample using hydration in presence of air circulation. The polymer concretes were characterized in terms of mechanical, thermal, structural and morphological properties. The properties showed increasing trends after cement addition. Results showed that the tensile strength of the polymer concretes were improved by 37.2%, 115.5%, 165.9%, and 40.6% for loading of 10, 20, 30, and 40 wt% cement, respectively. In addition, the flexural strength of the polymer concretes was also enhanced and found maximum (175.3% higher) in 30 wt% concrete compared to neat epoxy. Other mechanical properties of the polymer concrete were also found increasing. Moreover, decomposition temperature was raised nearly 15 C for adding 30 wt% cement which was the maximum among the other polymer concretes. For the case of hydration in presence of air circulation, the prepared composite showed the highest tensile mechanical performance with improved surface topography. From the results, it was concluded that the addition of cement into the epoxy was very effective to produce polymer concretes.

“…As a result of this background study, we should return to redox-active organic materials for next-generation ESSs as electrode material, because they offer significant benefits over metal-based inorganic materials with respect of desired molecular structure, outstanding chemical and physical characteristics, and high electrochemical energy storage capabilities. [16,17] More specifically, redox-active conductive polymers (CPs) have been mostly used for ESSs instead of organic single molecules with the same redox moieties because of the benefits of polymeric materials, including superior stability, good processability, and ease of fabrication. [18,19] A conjugated bond structure along the polymer chain makes conducting polymers conductive.…”

Conductive polymer (CP) research has exploded in popularity over the years, with applications ranging from nanoelectronics to material science. CPs are, for all sorts of purposes, Nobel Prize-winning compounds, as their inventors received the Nobel Prize in Chemistry in 2000. Conducting polymers have sparked a lot of interest in academic and industrial sectors because they combine the electrical characteristics of semiconductors and metals with the typical benefits of ordinary polymers, such as ease of preparation and low cost production. Conducting polymers have also received a lot of attention because of their unique characteristics, which include customizable electrical properties, excellent optical and mechanical capabilities, ease of synthesis and manufacturing, and superior environmental durability to traditional inorganic materials. In this study, the molecular structures and behaviors of the most common forms of CPs, namely, polyacetylene, polyaniline, polypyrrole, and polythiophene and derivatives of polythiophene are discussed. The transport phenomenon that allow to understand the conduction process, are also described in this review. An in-depth investigation of conducting polymerbased binary, ternary, and quaternary composites with carbon-based materials, metal oxides, transition metals, and inorganic particles is utilized to analyze their applications as supercapacitors and batteries. There are also explanations of recent advancements in their applications in the areas of energy storage systems including batteries and supercapacitors. The development of their applications in the energy storage devices such as supercapacitors, lithium, and other -ions batteries, as well as their current issues and future prospect to advance energy storage systems are broadly discussed. This review is intended to contribute to a better understanding of this conducting polymer and, as a result, to the development of new research areas.
