The mass attenuation coefficient of lead nitrate (Pb(NO3)2)-filled polycarbonate (PC) composite films were determined both computationally (using Baltakmen's and Thummel empirical formulae) and experimentally using 204Tl and 90Sr-90Y radio-isotopes for films at different filler levels 0, 5, 15, 25, 35 and 50 weight percent (Wt.%). In comparison with Thummel empirical formula, the values obtained from Baltakmen's empirical formula is in good agreement with the experiment.

The effect of bismuth nitrate pentahydrate (BNP) on the properties and microstructural features of polycarbonate (PC) has been investigated using PALT, XRD, SEM, EDX, TG, ATR-FTIR and tensile mechanical measurements. Positron Annihilation Lifetime Spectroscopy reveals that the ortho-positronium lifetime and its corresponding intensity significantly decrease as the filler level of BNP in PC (in the composite) increases from 0.3 wt% up to 5.

Potassium permanganate (KMnO) filled polyvinyl alcohol (PVA)-polyvinylpyrrolidone (PVP) polymeric blend films have been prepared by solution casting technique, with filler levels (FL) varying from 0.01 up to 4.70 mass%.
