A Waterborne Polyurethane CMC/PEDOT∶PSS Strain Sensor:Self-adhesive Properties and Sensing Performance
摘要
Abstract
Currently,flexible wearable sensing devices have attracted much attention due to their wide application in fields such as human-computer interaction.However,the restoration of signal values during the strain recovery process of flexible strain sensors is crucial for the application of these sensors.Therefore,in this experiment,we synthesized a photosensitive water-based polyurethane(UVWPU)using a one-pot method.We strengthened the interaction between UVWPU and poly(3,4-ethylene dioxythiophene)/polystyrene sulfonic acid(PEDOT∶PSS)through strong hydrogen bonds and Ca2+metal coordination,and enhanced the mechanical properties of the material using hydroxy methyl cellulose(CMC).As a result,we successfully prepared a flexible strain sensor with excellent mechanical properties.Due to the presence of multiple intermolecular forces and the enhancing effect of CMC,the reduction of effective conductive pathways caused by strain can be effectively repaired,enhancing the fatigue resistance and stability of the flexible strain sensor.During 1000 cycles of tensile tests,the sample maintained good signal sensing performance,and its self-adhesion and biocompatibility also proved its potential for application in flexible strain sensing devices.关键词
