“…These values are consistent with previous reports. For example, PVC plasticized with 66 wt-% di-2-ethylhexyl phthalate can have a resistivity as low as 1.63 MΩ·cm [41], but higher values are possible depending on the type of plasticizer and the membrane composition [42]. …”

A new miniaturization approach to create micro and nano-scale ISEs was demonstrated and the concept tested with an environmentally relevant chromate selective membrane consisting of 7.7:62.2:31.1 wt % Aliquat336:2-NPOE:PVC. Apertures of 100 nM and 30 μM dimensions were made using MEMS fabrication techniques and functionalized through a macroscale application of solvent polymeric membrane. Performance studies for the microscale ISE showed a response slope of −58.6 ± 5.6 mV decade−1 and Limit of Detection (LOD) of 2.1 10−5±1.1×10−5 M, versus −65.2 ± 4.2 mV decade−1 and 1.8×10−5 ± 6×10−6 M for the nanoscale ISE. This was consistent with control studies with carefully conditioned coated wire electrodes, which demonstrated a response slope of −61.7 ± 2.4 mV decade−1 and a LOD of 3.0×10−6 ± 1×10−6 M. Response times for the best micro- and nano-scale ISEs were in the 10 – 20 sec timeframe.. Electrical resistance measurements were in the GΩ range for the microscale ISEs and nanoscale ISEs. Appropriate ISE geometry was confirmed through AFM measurements and calculations based on electrical properties for micro- and nano- scale apertures. These micro- and nano-scale ISEs are expected to have significant impact in the field of micro-scale analytical processes.

“…The cable cover material must have high electrical insulation properties conjugated with high flammability resistance, providing maximum protection and safety levels [40][41][42][43]. Figure 12 represents the electrical behavior (volume resistivity-ρ) of plasticized poly(vinyl chloride) containing Oxydtron.…”

Many additives are used to improve the performance of cables in terms of increasing their flame retardancy, thermal stability, thermal conductivity, and other characteristics. Unfortunately, most of these additives contain heavy metals. Therefore, the main objective of this study is to introduce a material representing a new generation of environmentally friendly heavy metal-free stabilizers for cable grade poly(vinyl chloride) that can compete with traditional materials in terms of performance and distinctive properties. This unique additive is Oxydtron, a synthetic silicate or simply nanocement. The tests performed are rheological properties represented by a capillary rheometry analysis, limiting oxygen index, and volume resistivity. The most significant improvement in Bagley correction measurements was 14.61%; 18.13%; and 27.20% more than poly(vinyl chloride) basic formulation when using 5wt.% Oxydtron at 160 °C, 170 °C, and 180 °C, respectively. Also, the mean increases in relaxation time were 3.200 times, 8.825 times, and 12.458 times more than poly(vinyl chloride) basic formulation with 1wt.%, 3wt.%, and 5wt.% of Oxydtron, respectively. Furthermore, the Oxydtron lowered the value of the accompanying thermal gradient of the L.O.I test, reducing the heat-affected zone. The best result was with the extrusion processing method due to the uniformity of the processing conditions. However, the thermal gradient analysis showed residual heat stress in the test samples after cutting the burning layer and re-testing the samples again; this causes them to burn faster. This situation requires caution for designs that are exposed to high temperatures without burning. The optimum improvement in volume resistivity value was 14.71% and 38.24% more than poly(vinyl chloride) basic formulation after adding 5wt.% and 7wt.% of Oxydtron, respectively.
