Bull. https://doi.org/10.1007/s00289-018-2391-1 ORIGINAL PAPER Synthesis and studies on phosphazene core‑based POSS‑reinforced polyimide nanocomposites 1 2 Rajamanickam Revathi · Pichaimani Prabunathan · Muthukaruppan Alagar Received: 2 November 2017 / Revised: 6 April 2018 / Accepted: 27 May 2018 © Springer-Verlag GmbH Germany, part of Springer Nature 2018 Abstract In the present work, phosphazene core-based polyimide and polyhedral oligomeric silsesquioxane (POSS)-reinforced phosphazene polyimide nanocompos- ites were developed and characterized. The molecular structure of cyclophospha- 1 13 zene amine (PZA) was confirmed by H, C NMR and MASS spectroscopic meth- ods. The developed polyimide and its composites were studied for optical, thermal and dielectric properties along with their morphological studies. Interestingly, it was found that the incorporation of 10 wt% of POSS-reinforced PZI composites pos- sesses an improved glass transition temperature (Tg), thermal stability, char yield and flame-retardant behavior than those of neat PZI matrix. The value of dielectric constant gets decreased with increasing the weight percentages of POSS reinforce- ment and thus 10 wt% POSS-reinforced PZI composites possesses the lowest value of dielectric constant (k = 2.1). Further, it also possesses the highest UV shielding behavior in UVA region, i.e., 93% with minimum weight loss even after exposing for 165 h. The antibacterial activity of the neat
