Facile Fabrication and Analysis of Highly Sensitive PtTFPP/Carbon Black/Polystyrene Oxygen-Sensitive Composite Films for Optical Dissolved-Oxygen Sensor

“…Oxygen is a crucial element for the proper functioning of the human body. − It plays a key role in several reactions in the fields of medicine and chemistry. , Oxygen exists in diverse forms in nature, including the form of dissolved oxygen, , which is the oxygen exchanged between a solution and the atmosphere or that dissolved in water through chemical reactions. , It holds significant importance as an indicator in aquaculture. − Maintaining an appropriate oxygen level is very important to aquatic life; both excessively high and low levels can be very dangerous. For instance, fish may suffocate and die if the dissolved-oxygen level falls below 4 mg/L .…”

Polydopamine/Carbon Black/Carbon Nanofiber/Thermoplastic Polyurethane Composite Nanofiber Strain Sensor with Ultrahigh Loading Rate for Human Activity Monitoring

“…Based on previous studies, increasing the loading sites of the substrate or the loading rate per unit area to improve the anchoring amount of the active filler can increase the density of the conductive network as well as the conductivity in the functional layer, expand the resistance variation interval, and thus improve the sensitivity and response range of the device . The porous structure and nanoscale present in the nonwoven fiber membranes prepared by the electrospinning process enable them to have a specific surface area and surface activity that far exceed those of dense membranes, which can provide more loading sites and attachment efficiency, and thus are often used as a reliable choice for CPC sensor substrates. , By anchoring CNT to thermoplastic polyurethane (TPU) nanofiber membranes, Yu et al prepared a composite fiber sensor that achieved a gauge factor (GF) of 110.0 in the commonly used response range of 0–50%, with the corresponding wet-spun-prepared micron fiber substrate performing at only 10.2. , Significant increases in loading rates can be achieved by improving the dispersion of the active filler or its compatibility with the substrate, inhibiting agglomeration of the active material, and promoting selective adsorption with the substrate. As nonpolar material with inert surface, CB and CNF tend to agglomerate in water with low dispersibility.…”
