“…48,50 The oxidation state of Fe was 3+ due to the satellite features of Fe 2p. 48,50 [52][53][54][55] The sp 2 (CvC) peak of the NZF-PANI nanohybrid was noticeably more intense, which could be due to the polyaniline expanded-conjugation network. The deconvolution of the N 1s core-level spectrum yielded two large peaks at 399.10 and 401.60 eV, which represent the imine and amine groups, respectively.…”

“…Some studies have gone ahead to prepare MNP/PANI by physically blending PANI and MNPs dispersions (self‐assembly method). This approach has showed to prevent severe structural deformation of the embedded nanoparticles that sometimes happen in the case of in‐situ polymerization due to the extremely low pH of the polymerization reaction solution [120]. For example Afzal et al ., 2009 [16] synthesized Au/PANI nanocomposites by mixing pre‐prepared PANI and AuNPs.…”

Polyaniline (PANI) is one of the most extensively used conducting polymer due to its fascinating properties including conducting, thermal, optical, magnetic and electrochemical properties, simple synthesis procedure and low cost of monomer. It has attracted major attention in a variety of applications including electrochemical sensors, catalysts, supercapacitors and biosensors. However, its limitations such as insolubility in common solvents, low process‐ability and poor mechanical properties have led to the development of new approaches to improve it properties. Metal nanoparticles (MNPs) such as silver, gold, copper and palladium have been combined with PANI to improve on its properties which has led to a new class of materials known as metal/PANI nanocomposites. These hybrid nanocomposites incorporate advantages of both MNPs and polymers which effectively improves the properties of the individual materials. Various synthesis techniques including in situ polymerization, ɤ‐radiolysis, electrodeposition, complexation, vacuum deposition and interfacial polymerization have been used in the formation of metal/PANI nanocomposites. These nanocomposites have been used in various sensor and biosensor applications due to their excellent conductivity, ease of synthesis, excellent redox potentials, chemical and thermal stability. This review highlights the various metal/PANI nanocomposites, their various synthesis techniques and their application in sensors and biosensors. The importance of these nanocomposites in sensing and signaling various toxic heavy metals such as mercury, lead and silver and toxic gases such as hydrogen sulphide, ammonia and chloroform has been discussed. In addition the review covers the applications of metal/PANI nanocomposites in biosensor systems for the detection of glucose, DNA, protein, cholesterol, drugs and hydrogen peroxide.

“…The synthesis of composites involving conducting polymers and AgNP plays a crucial role in advancing their applications. − Various methods have been used to synthesize these composites, such as (a) using the monomer as a reductant for the metal ions, , and (b) synthesizing metal nanoparticles separately and then dispersing them in a polymer matrix. − The approach that uses the monomer as a reductant has significant advantages, such as simplicity and a more uniform distribution of nanoparticles within the polymer matrix, which enhances the composite properties …”

This study presents an approach to synthesizing a nanocomposite of polythiophene and silver nanoparticles (PBT/ Ag), which addresses the challenge of AgNP aggregation and its impact on the catalytic efficiency. The reaction was performed under mild conditions using an ionic liquid, specifically bis-(trifluoromethylsulfonyl)imide (Tf 2 N) 1-butyl-3-methylimidazolium (BMIm), which acted as both a solvent and a template. The nanocomposite contained uniformly dispersed spherical silver nanoparticles with an average diameter of around 10 nm in polythiophene doped with Tf 2 N anions. The catalytic efficiency of the composite was assessed by reducing 4-nitrophenol to 4aminophenol using sodium borohydride. This transformation converts environmentally harmful 4-nitrophenol into the less toxic 4-aminophenol, a crucial intermediate in pharmaceuticals, such as paracetamol. The composite displayed notable efficiency, achieving a 99.9% conversion rate within 10 min, and exhibited recyclability over multiple cycles. This study represents the first use of a polythiophene derivative and a silver nanoparticle composite as a heterogeneous catalyst, marking an advancement in catalysis and materials science.
