Modification of Electrical Properties of Silver Nanoparticle

Abstract

This chapter focuses on the synthesis of silver nanoparticles (AgNPs), AgNP composites, and its role in the structure and electrical properties modification. The research and its various applications of nanoparticles are interesting among others. Silver nanoparticles (AgNPs) are now becoming to take an essential role in the diverse field of application.Establishing the simple and inexpensive of AgNPs is greatly required, since it will also influence it used. Many different methods to obtain AgNPs have been reported. The inducing AgNPs on a various number of other materials has been investigating. We report a brief review of simple AgNP fabrication method at different MSA, PEG, and ultrasonic irradiations regarding its structure and conductivity. We also report the influence of AgNPs on the electrical conductivity of conducting polymers, i.e., PANI, flavonoids of Jatropha multifida L. (JML) and Pterocarpus indicus W. (PIW). It is found that in general, the increase of AgNP concentration gives rise to increase of its electrical conductivity. The conductivity of the AgNPs doped of polymers does not directly reflect by its crystallinity or crystal size. Some exciting aspect of crystal structure and its conductivity are discussed.

“…Electronics: Nanosilver can create conductive materials for use in electronic devices, such as computers and smartphones. It can also be used as printed circuit boards and other electronic components [ 218 ].…”

Nanobiotechnology: Nature-inspired silver nanoparticles towards green synthesis

“…The prominence of AgNPs is attributed to their well-documented properties, such as antimicrobials, high electrical and thermal conductivities, catalytic activities, and many more, promoting a variety of new products and scientific applications. 5,24,25 By 2024, healthcare applications such as medicine and life sciences are estimated to be worth more than $1 billion, followed by textile applications, which are anticipated to surpass $750 million, and food and beverages forecasted to hit more than $300 million. 40,41…”

“…21 AgNPs are tremendously demanded by the industry thanks to their unique physical, chemical, and biological properties, on top of high-sensitivity biomolecule detection, diagnostics and therapeutics, antimicrobial activity, and high electrical and thermal conductivity, catalysis, and many more (Figure 1). 22–25 In order to fulfil the high demand for AgNPs, various methods have been adopted to synthesis AgNPs, either conventional physical or chemical methods. Simple protocol, eco-friendly, rapid synthesis, cost-effectiveness, and abundant resources of reducing and stabilising agents, nevertheless, successfully place the biological approach in its own class and gain much interest from industry players.…”

Influence of in situ photo-induced silver nanoparticles on the ageing of acrylate materials

“…Among many types of nanoparticles (NPs) available and dispersible in a polymer matrix, silver nanoparticles (AgNPs) were tested and evaluated. These nanoparticles are capable of imparting antimicrobial activity [6,7], or optical [8] and conductive [9,10] properties to the polymer material. However, the key characteristic of this type of material remains the durability of the polymeric matrix in the specific environment in which it is to be used.…”
