Abstract

Chitosan (CS)/boron nitride nanoplatelet (BNNP) nanobiocomposite films were successfully prepared. Morphological results showed good dispersion of BNNPs in the CS matrix. After loading with BNNPs, water solubility (WS) and moisture absorption of the CS film decreased. The WS decreased from 41.2 to 27.8% at 7 wt% BNNP loading. Additionally, water vapor permeation decreased from 4.2 × 10⁻¹¹ for pure CS film to 2.9 × 10⁻¹¹ g m⁻¹s⁻¹Pa⁻¹ at 7 wt% BNNP inclusion. The oxygen permeability of CS film decreased by up to 84% at 7 wt% BNNP loading. The composites showed better sodium hydroxide resistance compared with pure CS. Thermal stability of the composites was higher than the pure CS, up to 35 °C increase at 7 wt% BNNP loading. The addition of 5 wt% BNNPs improved Young's modulus by up to 45% compared with pure CS film. Cytotoxicity of the films decreased after loading with BNNPs.
