In the present study, the effects of partially water-soluble nanoscaled boron phosphate (BPO4)

on the mechanical properties of poly (vinyl alcohol) (PVA) plasticised with ethylene glycol films

were investigated for the first time. Firstly, BPO4 was synthesised at 500°C using boric acid and

phosphoric acid as precursors. Then, nanoscaled BPO4 was obtained by the ultrasonic

homogenisation method. Finally, PVA/BPO4 composite films were prepared by the solvent

casting method with different BPO4 weight ratios. As a result of mechanical studies of the

composites, it was found that the tensile strength of pristine PVA was enhanced from 19.06

to 26.42 MPa with the addition of nanoscaled BPO4. Furthermore, the tensile moduli of the

composites reached their maximum at 4.56 GPa for the composite with 7% BPO4 by weight.

This indicates that BPO4 is a promising material as an additive for low-cost composite films

with high mechanical performances.
