“…The blend was then pressed in an IQAP-LAP model PL-15 hydraulic press for 6 minutes at 150 ºC, resulting in polymeric plates with an average thickness between 0.5 and 1 mm. The OG compatibilizer, which presents an alkyl chain almost identical to DBSA, was selected in order to improve the solubility and conductivity of the blends [34].…”

Smart materials for sensor applications are increasingly being used in a wide variety of applications ranging from engineering to medical devices. This work reports on piezoresistive sensors based on conductive polyaniline and thermoplastic elastomer processed by conventional polymer extrusion. The material presents excellent processability and piezoresistive performance offering an alternative to traditional composites with conductive nanofillers for sensor applications.The polyaniline/ styrene-butadiene-styrene (PANI/SBS) conductive polymer blends present good mechanical properties, high electrical conductivity and piezoresistive response. The maximum strain reaches ≈60% for 30 weight percentage (wt%) PANI content and the electrical conductivity is σ ≈0.1 S/m for blends with 40 wt% PANI content. Further, the sample with 40 wt% PANI content shows a piezoresistive gauge factor GF ≈1 for deformation measurements between 0.1 to 3 mm in bending cycles.

Cyclic temperature dependence of electrical conductivity in polyanilines as a function of the dopant and synthesis method

Most of the studies dealing with polyanilines (PANIs) are focused on electrochemical polymerization; however, chemical polymerization is more suitable for large-scale production. In order to develop commercially viable, clean, effective materials for thermal sensor devices, temperature dependent electrical response has been studied in PANIs obtained by simple, low-cost synthesis conditions, transferable to industrial processing. PANIs doped with HCl, dodecylbenzene sulfonic acid (DBSA) and sodio-5sulfoisophtalic acid (NaSIPA) were prepared by chemical oxidative polymerization, through direct and indirect routes of synthesis. TEM images disclosed formation of nanorods and microfibrils. Microstructural analysis confirmed differences in doping level and crystallinity which were related with the PANI conductivity. Two PANI-DBSA synthesized by direct and indirect methods, exhibit the best conductivity retention up to 150 ºC. In cyclic tests, they show excellent performance after 4 heating-cooling cycles up to 70 ºC. The amplitude of electrical response for 2 PANI-DBSA obtained by direct synthesis is twice the value of PANI-DBSA prepared by indirect route. Conversely, the latter displays slightly better repeatability due to its lower moisture content. This study suggests that both PANI-DBSA are suitable for use in electronic applications, under ambient conditions below 150 ºC, and are promising materials for temperature sensor applications.
