Typical solid-state reaction was accomplished by simply heating the physical admixture of the two reactants i.e. AgNO3 and PPS by varying molar ratios mainly 1:1, 1:5, 1:15, 1:20, at the crystalline melting temperature (285 degrees C) of PPS. The synthesized nanoparticles were characterized by various physico-chemical techniques like X-ray Diffractometry, Scanning Electron Microscopy equipped with EDAX, Transmission Electron Microscopy and UV-Visible spectroscopy. The prima facie observations suggest the effective formation and subsequent entrapment of mainly nanocrystalline metallic silver (fcc) in PPS matrix for all the molar ratios chosen for the reaction. Additionally, simultaneous occurrence of nanocrystalline Ag2S (monoclinic phase) is also noticed in case of heated admixture of AgNO3: PPS with equimolar ratio. The TEM analysis reveals nanoscale polydispersity (5nm to 70nm) and prevalence of mainly spherical morphological features in all the cases with occasional indications of triangular and hexagonal morphological features depending upon the reaction molar ratio.</p>10aAg10aAg2S10aNanoparticles10aPolymer inorganic solid -state reaction10aThermoplastic polymer matrix1 aWaghmare, Sujata1 aShinde, Manish1 aGholap, Ramkrishna, S.1 aRao, Koteswara1 aHawaldar, Ranjit, R.1 aMulik, Uttam, P.1 aAmalnerkar, Dinesh, P.  uhttps://library.ncl.res.in/content/concurrent-situ-formation-agag2s-nanoparticles-polymer-matrix-facile-polymer-inorganic-0
