Abstract

A novel capacitive sensor for measuring the water-level and monitoring the water quality has been developed in this work by using an enhanced screen printing technology. A commonly used environment-friendly conductive polymer poly(3,4-ethylenedioxythiophene):poly (styrenesulfonate) (PEDOT:PSS) for conductive sensors has a limited conductivity due to its high sheet resistance. A physical treatment performed during the printing process has reduced the sheet resistance of printed PEDOT:PSS on polyethylenterephthalat (PET) substrate from 264.39 Ω/sq to 23.44 Ω/sq. The adhesion bonding force between printed PEDOT:PSS and the substrate PET is increased by using chemical treatment and tested using a newly designed adhesive peeling force test. Using the economical conductive ink PEDOT:PSS with this new physical treatment, our capacitive sensors are cost-efficient and have a sensitivity of up to 1.25 pF/mm.

摘要

在这项工作中，通过使用增强型丝网印刷技术开发了一种用于测量水位和监测水质的新型电容式传感器。用于导电传感器的常用环保导电聚合物聚（3,4-乙撑二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT:PSS）由于其高表面电阻，导电性有限。在印刷过程中进行的物理处理将聚对苯二甲酸乙二酯（PET）基板上印刷的PEDOT:PSS的表面电阻从264.39Ω/sq降低到23.44Ω/sq。通过化学处理提高了印刷的PEDOT:PSS与PET基板之间的粘附力，并使用新设计的粘合剂剥离力测试进行了测试。使用经过这种新物理处理的经济导电油墨PEDOT:PSS，我们的电容式传感器具有成本效益，灵敏度高达1.25 pF/mm。
