“…A variety of synthetic antioxidant polymers, including polyaniline, polypyrrole, thiophene polymers, phospholipid polymers, polysulfide, and so on, have been shown to exhibit important biological activities including ROS scavenging, anti‐inflammatory activity, and protein inhibition. Kumari et al [ 56 ] have observed that the radical scavenging property of the polyaniline has not been dependent on surface area and the conductivity of polyaniline, but it subject to the various oxidation state of polyaniline. As a result, it has been observed that the antioxidant property has been increased with decreasing in the level of polyaniline oxidation.…”

Reactive oxygen species (ROS), the byproducts of aerobic metabolism, is a class of crucial molecules in physiological processes, nevertheless, would induce a series of inflammatory responses when overexpression. Excessive or inappropriate inflammation contributes to a range of acute and chronic human inflammatory diseases. In recent years, ROS scavenging agents have been widely regarded as a kind of potential therapeutic substances due to their abilities of delaying and/or inhibiting the oxidative stress in physiological microenvironments. ROS scavenging biopolymers are a group of agents that commonly have strong ROS scavenging ability and pharmacokinetic potential compared to similar low molecular weight agents. In this review, the generation and clearance of ROS in physiological processes, as well as the effects of ROS inflammatory diseases are introduced. Furthermore, the classification, macromolecular structure, and scavenging mechanism of those antioxidant polymers are systematically described and discussed, which aim to provide a guiding theoretical reference of designing effectively ROS scavenging biopolymers for anti‐inflammatory disease therapy.

Conducting polymers were found to have great potential in biomedical applications such as tissue engineering during the 1990 s due to its behaviour to modulate cellular activities like proliferation, cell adhesion and differentiation via electrical stimuli (Boni et al, 2018;Guimard et al, 2007;Stenger-Smith, 1998;Wong et al, 1994).…”

Biomaterials are natural or synthetic materials that are biodegradable and interact cordially with biological systems (Qu et al., 2019). These can be well-defined as a material envisioned to interface with biological systems for evaluation, treatment and replacement of organs, tissues or function of the body (Basu & Ghosh, 2017; Reis et al., 2016). They play a key role in the human health system which is attained from nature or the environment (Mir et al., 2018). Generally, biopolymers are the main class of biomaterials as biopolymers are biocompatible, biodegradable and human body-friendly (Rebelo et al., 2017). These biopolymers are further classified as biodegradable and non-biodegradable according to their nature (Andreeßen & Steinbüchel, 2019; Kabir et al., 2020). Due to their outstanding biocompatibility, biodegradable polymers are known as the best candidate for biomedical applications such as drug delivery systems, vascular grafts, surgical sutures, artificial skin, bone fixation devices, gene delivery systems, tissue engineering and diagnostic applications. Biomedical engineering is an attractive branch which deals with engineering and biology together to put on engineering materials and rudiments in the field of healthcare and medicine. Tissue engineering is also a part of it that fulfils the purposes of recovering or exchange failing or broken body tissue by merging cells, scaffolds and bioactive molecules. Scaffolds should combine various functions such as biodegradability, biocompatibility, ideal mechanical strength, adequate porosity for small molecule transportation, controllability, implantation and sterilization. Hence, natural polymers such as gelatin and chitosan are the perfect match for scaffold fabrication and synthetic aliphatic polyesters too. However, these revealed poor hydrophilicity which limits the cell attachment on surfaces and lack of sites for covalent bonding. While having their biodegradable nature, biopolymers or conventional polymers are insulators in nature so that limits the use in some biomedical applications where conducting properties of biomaterials is indispensable (George et al., 2020). In many applications of implants in the body, such as in bone fixing materials, dental materials and bone substitution materials, there is a need for such type of material showing long-term stable performance. In other applications such as controlled drug delivery, regenerative medicine, tissue engineering

“…One of the most promising methods to prepare conducting core-shell PANI/inorganic composites is through an in situ chemical polymerization of a monomer in the presence of inorganic components. Many groups have reported conducting PANI/inorganic core-shell composites such as PANI/Y 2 O 3 [ 15 ], PANI/Zn x Fe 3−x O 4 [ 16 ], PANI/T-ZnOw [ 17 ], PANI/TiO 2 [ 18 ], PANI/MnO 2 [ 19 ], PANI/ZrO 2 [ 20 ], PANI/alumina [ 21 , 22 , 23 ], PANI/attapulgite (ATP) [ 24 ], and PANI/clay [ 25 ].…”

Polyaniline doped with dodecylbenzenesulfonic acid/χ-aluminum oxide (PANDB/χ-Al2O3) conducting core-shell nanocomposites was synthesized via an in situ polymerization method in this study. PANDB was synthesized in the presence of dodecylbenzenesulfonic acid (DBSA), which functioned as a dopant and surfactant. The electrical conductivity of the conducting PANDB/χ-Al2O3 core-shell nanocomposite was approximately 1.7 × 10−1 S/cm when the aniline/χ-Al2O3 (AN/χ-Al2O3) weight ratio was 1.5. The transmission electron microscopy (TEM) results indicated that the χ-Al2O3 nanoflakes were thoroughly coated by PANDB to form the core-shell (χ-Al2O3-PANDB) structure. The TEM and field-emission scanning electron microscopy (FE-SEM) images of the conducting PANDB/χ-Al2O3 core-shell nanocomposites also indicated that the thickness of the PANDB layer (shell) could be increased as the weight ratio of AN/χ-Al2O3 was increased. In this study, the optimum weight ratio of AN/χ-Al2O3 was identified as 1.5. The conducting PANDB/χ-Al2O3 core-shell nanocomposite was then blended with water-based polyurethane (WPU) to form a conducting WPU/PANDB/χ-Al2O3 blend film. The resulting blend film has promising antistatic and electrostatic discharge (ESD) properties.
