Polymer chemosensors as solid films and coated fibres for extreme acidity colorimetric sensing

“…The absorbance data at 533 nm are useful for determining the acidity of a system taking a single UV/Vis spectrum (continuous lines correspond to the fitting using eqn (18)); (b) species distribution using eqn (10) and (11) assigning to C T a value of 100. stimuli responsive, to be used in apparels as stand-alone systems to be used as communication devices, energy-storage tools, actuators and sensors to name but a few applications. [34][35][36][37] Within this context, intelligent fabrics capable of sensing acidic media with macroscopic colour changes are of especial interest. Thus, conventional cotton and high-tech para-aramid fabrics were prepared and subjected to an acid environment, both in water solution and in the gas phase, exhibiting a clear colorimetric response, as depicted in Fig.…”
