Silver nanoparticle (AgNP) is an attractive component for hollow MNPs due to its superior electrical conductivity as well as cost effectiveness. [17][18][19][20] The hollow interior will endow with further material economy, high dispersity, increased active surface area, and low density to reduce the sedimentation problem. Significant contribution has been made in the development of hollow Ag functional nanomaterials. Submicrometer-sized hollow Ag spheres were prepared using poly(ethylene oxide)block-poly(methacrylic acid)-sodium dodecylsulfate utilizing strong interaction between the polymer and the surfactant forming complex structure in aqueous solution. [21] Phase-transformable emulsions composed of natural beeswax were also employed for templated synthesis of hollow Ag spheres. [22] Hollow AgNP cages were built with building blocks of AgNPs by layer-by-layer assembly. [23] These methods contain several advantages such as, one-pot methodology [21] and easily removable soft template. [22] However, any specific applications were not explored. To the best of our knowledge, there are no reports on hollow AgNP/polymer nanosphere conductive inks and transparent materials in a facile one-pot procedure.The major challenge for AgNP inks faced is removal of stabilizers before or during sintering process, either by bulk heating or selective welding, [24][25][26] in order to reduce the resistance at the junction. As a consequence, these inks are required to have complicated modifications [27][28][29] or compositions. [30,31] Polymer stabilizers are especially problematic in removal in spite of their good stabilization abilities. In addition, the annealing process often makes the structure denser and therefore leads to decrease in the optical transmittance. A highly conductive material in our earlier study, poly(NVKco-MAH)-g-(NH-(PPO 31 -co-PEO 19 )@Pd hollow nanospheres, implies a solution for this challenge. [32] The ink of the polymer@Pd nanospheres could be inkjet-printed in patterns. The printed patterns of the polymer@Pd nanospheres exhibited excellent conductivity as well as the remarkable catalytic ability even without removal of the organic parts owing to the presence of Pd outside the sphere. However, the potential applications of the Pd-based conductive patterns are limited to plating catalysts, [33][34][35][36] due to the higher cost factor of Pd toward the conductivity. Substituting the Pd shell with the Ag analog will realize printable materials with excellent conductivity without annealing in a better cost factor if the same strategy is available. Here, we report a facile fabrication method for highly conductive hollow polymer@Ag ink. The Development of printable conductive inks for applications in printable electronics by facile methods is important. Here, this study demonstrates a robust and facile one-pot approach for printable polymer@Ag nanospheres with well-defined hollow morphology. The polymer@Ag nanospheres are fabricated through metal-complexation induced phase separation assisted by a functionali...

“…Moreover, the addition of metal salt into a substrate also affects the morphology of films. Sajjad developed an approach to preparing a polymer-Ag honeycomb film by casting a polymer solution on an aqueous silver nitrate solution [33]. They found that the metal-complexation-induced phase separation approach allowed the formation of a well-defined honeycomb film.…”

Honeycomb films pore-filled with metal (Au, Ag, and Cu) nanoparticles were successfully prepared by combining the breath figure method and an in situ reduction reaction. First, a polyhedral oligomeric silsesquioxane (POSS)-based star-shaped polymer solution containing metal salt was cast under humid conditions for the formation of honeycomb films pore-filled with metal salt through the breath figure method. The morphology of the honeycomb films was mainly affected by the polymer molecular structure and the metal salt. Interestingly, the promoting effect of the metal salt in the breath figure process was also observed. Then, honeycomb films pore-filled with metal nanoparticles were obtained by in situ reduction of the honeycomb films pore-filled with metal salt using NaBH4. Notably, the metal nanoparticles can be selectively functionalized in the pores or on the surface of the honeycomb films by controlling the concentration of the NaBH4. Metal-nanoparticle-functionalized honeycomb films can prospectively be used in catalysis, flexible electrodes, surface-enhanced Raman spectroscopy (SERS), and wettability patterned surfaces.

Water comprises an integral component of human life and its accessibility is essential for all life in the entire planet. Due to climate changes and other manmade activities, the world is facing shortage of drinking water. There are a number of pollutants present in the water such as gases, chemicals and heavy metals. Therefore, it is imperative to decontaminate water for a healthy planet. There are numerous problems and challenges of wastewater treatment. For better ecological and health issues some measures are required to take in advance to avert possible evil or to secure good results. Metal-based nanomaterials have found exceptional use in the decontamination purpose due to their nature which arises from nanosize, such as better adsorption and catalytic activity. Metal-based nanomaterials can productively remove different contaminants from water and they have been effectively applied in decontamination of water. Due to having larger surface area and having ability to work at low concentration these metal-based nanomaterials are very efficient in wastewater treatment. Nanoengineered nanoparticles impart a promising and effective treatment method to wastewater and thus can be adapted simply. Modern techniques for treatment of wastewater must be cost-effective and accessible for commercial use. In this chapter, we outline the role of metal-based nanoparticles and nanocomposites applied in water decontamination. Moreover, we discuss the advantages, disadvantages, shortcomings and future prospects associated with these nanomaterials.
