Abstract

ABSTRACT 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.

聚乙烯醇/磷酸硼纳米复合材料力学性能的增强

摘要:本文首次研究了部分水溶性纳米级磷酸硼(BPO4)对聚乙烯醇(PVA)乙二醇增塑膜力学性能的影响。首先，以硼酸和磷酸为前体，在500℃下合成BPO4。然后采用超声均质法制备纳米级BPO4。最后，采用溶剂浇铸法制备了不同BPO4质量比的PVA/BPO4复合薄膜。对复合材料的力学性能进行了研究，发现纳米BPO4的加入使原始PVA的抗拉强度从19.06提高到26.42 MPa。当BPO4质量分数为7%时，复合材料的拉伸模量在4.56 GPa时达到最大值。这表明BPO4是一种很有前途的低成本、高机械性能的复合薄膜添加剂。

期刊介绍： Plastics, Rubber and Composites: Macromolecular Engineering provides an international forum for the publication of original, peer-reviewed research on the macromolecular engineering of polymeric and related materials and polymer matrix composites. Modern polymer processing is increasingly focused on macromolecular engineering: the manipulation of structure at the molecular scale to control properties and fitness for purpose of the final component. Intimately linked to this are the objectives of predicting properties in the context of an optimised design and of establishing robust processing routes and process control systems allowing the desired properties to be achieved reliably.
