# Novel polystyrene-based nanocomposites by phosphorene dispersion

## TL;DR

This study develops polystyrene-based nanocomposites with dispersed phosphorene nanoflakes, demonstrating enhanced thermal and photo-stability due to effective dispersion and synergistic effects of the nanofiller.

## Contribution

It introduces a solvent blending method for embedding black phosphorus in polystyrene, with comprehensive characterization showing improved stability and dispersion.

## Key findings

- Enhanced thermal stability of nanocomposites
- Improved photo-stability compared to pure polystyrene
- Effective dispersion of phosphorene nanoflakes confirmed

## Abstract

Polystyrene-based phosphorene nanocomposites were prepared by a solvent blending procedure allowing the embedding of black phosphorus (BP) nanoflakes in the polymer matrix. Raman spectroscopy, X Ray Diffraction and TEM microscopy were employed to characterize the structural and the morphological characteristics of the achieved hybrids, with the aim to evaluate the dispersion level of black phosphorus layers. TGA, DSC analysis as well as thermal oxidation and photo-degradation techniques were employed to investigate the thermal- and the photo-stability of the samples. The collected results evidenced better thermal and photostability of both polymer matrix and dispersed layered phosphorus, suggesting really interesting polymer-nanofiller synergic effects ascribable to the presence and the good dispersion of the 2D-nanomaterial.
