利用自动穿孔测试仪，发展了一种通过局部溶剂银纹将发光染料掺杂到聚苯硫醚(PPS)薄膜中的新方法。所制备的传感器具有0-100kPaO-2范围内的灵敏度、高亮度、线性斯特恩-伏尔默曲线、低温度依赖性和低湿度交叉敏感性。此外，传感器不会渗入到食品模拟物中，可以集成到当前的食品包装材料中。这种方法允许连续生产离散的O-2传感器，并将其集成到包装材料中。(C)2015爱思唯尔有限公司。保留所有权利。
A new method for incorporating luminescent dye into polyphenylenesulphide (PPS) films by localised solvent crazing was developed using an automated puncture test instrument. The fabricated sensors displayed sensitivity over 0-100 kPa O-2 range, high brightness, linear Stern-Volmer plots, low temperature dependence and low cross-sensitivity to humidity. In addition, the sensors exhibited no leaching into food simulants and can be integrated into current food packaging materials. This approach allows continuous production of discrete O-2 sensors and their integration in packaging materials. (C) 2015 Elsevier Ltd. All rights reserved.
