Keywords: Gamma radiation, electrical conductivity, PVA-CH compositesAbstract.The effects of radiation on polymer composite PVA-based organic blends containing chlorine have been studied for their potential applications in electrochemical devices. The polymer composite PVA-Chloral Hydrate (CH) were blended separately with 23, 34, 45 and 57% CH. The composite films were prepared by solvent-casting method and each film has been irradiated with g-rays at different doses up to 12 kGy. The electrical properties have been studied using an impedance analyzer of LCR meter in the frequency range from 20 Hz to 1 MHz. The conductivity-dose relation study revealed that increase in conductivity of the irradiated PVA-CH blends with increasing dose up to 12 kGy. The increase in the conductivity with dose is attributed to the increase of ionic carriers in the composites induced by radiation scission of CH molecules and also due to hydrolysis of water.

To avoid conductive failure due to the cracks of the metal thin film under external loads for the wearable strain sensor, a stretchable metal/polymer composite film embedded with silver nanowires (AgNWs) was examined as a potential candidate. The combination of Ag film and AgNWs enabled the fabrication of a conductive film that was applied as a high sensitivity strain sensor, with gauge factors of 7.1 under the applied strain of 0–10% and 21.1 under the applied strain of 10–30%. Furthermore, the strain sensor was demonstrated to be highly reversible and remained stable after 1000 bending cycles. These results indicated that the AgNWs could act as elastic conductive bridges across cracks in the metal film to maintain high conductivity under tensile and bending loads. As such, the strain sensor engineered herein was successfully applied in the real-time detection and monitoring of large motions of joints and subtle motions of the mouth.
