In this article we present textile sensors for the continuous monitoring of electrocardiograms (ECG), made from fabrics coated with high electrically conductive poly(3,4-ethylenedioxythiophene) (PEDOT). Polymer coatings of PEDOT were in situ synthetized on plain weave fabrics of polyester by the vapour phase polymerization method, using aqueous oxidant solutions of Fe (III) chloride with a concentration of one molar, two polymerization layers and optimized process parameters. The coating provided fabrics with high electrical conductivity, characterized by a sheet resistivity of 10 Omega sq(-1). PEDOT coated fabrics and commercial conductive fabrics were made into sensors using a digital embroidery method. The performance of the sensors was analyzed by measurements of signal to noise ratio (SNR) under dry and moisture conditions and compared to those obtained with gel electrodes. The PEDOT sensors exhibited good performance characterized by SNR levels of the order to those obtained with gel electrodes. ECG sensors made of different types of fabrics exhibit significant differences in the noise amplitude, suggesting that the textile fibres and surface morphology are relevant parameters to consider in the sensor's design, affecting the contact resistance electrode-skin. The sensor's resistance to washing cycles was tested under various temperature and detergent conditions. The experimental results indicate that the lifetime of the electrodes can be considerably enhanced with detergent solutions of dodecylbenzenesulfonate (DBS). (C) 2015 Elsevier B.V.

Summary: In this study, a novel type of D-A non-fused-ring copolymers was designed and synthesized to overcome the trade-off relationship between electrical conductivity and Seebeck coefficient in organic semiconductors. The incorporation of fluorine atoms into the polymer backbone effectively increased the ordered degree of molecular stacking and improved both the electrical conductivity and Seebeck coefficient. The bimodal orientation of polymers played a crucial role in decoupling the correlation between electrical conductivity and Seebeck coefficient.

Fluorescence detection of hazardous metals using polyaniline-supported layered double hydroxide nanocomposite

Summary: This research focuses on the versatile substance, polyaniline/layered double hydroxide (PANI@Nd-Co/LDH), under solvothermal conditions. A thorough analysis of its structure and morphology was conducted using various analytical methods. The findings showed that PANI@Nd-Co/LDH exhibited highly sensitive and specific fluorescence detection of Pb(II) and Al(III), outperforming other heavy metal ions. The sensor demonstrated a turn-off fluorescence response for Pb(II) ions and a turn-on fluorescence response for Al(III) ions. The minimum detectable limits (MDL) were determined to be 9.6 nM for Pb(II) and 220 nM for Al(III). PANI@Nd-Co/LDH could be easily regenerated and reused for multiple cycles. The detection mechanisms involved the inner filter effect (IFE) for Pb(II) and the chelation-enhanced fluorescence (CHEF) effect for Al(III). These results highlight the excellent potential of PANI@Nd-Co/LDH in the detection and recognition of Pb(II) and Al(III) ions.
