Abstract
In this scientific article, the potential of producing a highly capable sensor by the addition of electric conductive carbon black (CB) to polymer composite was studied, and the effects of various carbon black content on ethylene-butene copolymer (EBC) on rheological and electromechanical were investigated. Electric conductive composites have many attempts at producing original material in technology as a sensor. The amount of (0, 4.07, 6.31, 8.71, and 11.28) volume % of CB was introduced to EBC using Brabender, mixed, and homogenized for 5 min at 180 °C. The dynamic mechanical analysis (DMA) and electromechanical test show that the addition of CB to the EBC would increase the viscosity, modulus, while electric resistance significantly decreased and changed greatly with elongation. The modulus increased from 8.9 to 15 MPa by increase of from 15 to 25 wt% of CB while the gauge factor decreases for about five times by increasing the CB from 15 to 25 wt% under 5 N force. These works demonstrate the possibility of producing strain sensors using a cheap and versatile technique, with potential health and electromechanical sensors.
Highlights
The fast development of smart sensors has contributed to smart elastic strain sensors
The scope of this paper is to investigate the mechanical and electromechanical properties of conductive carbon black (CB) on ethylene Butene copolymer prepared with Brabender contain a various ratio of Carbon black (CB) have been investigated
The creep compliance graph shows that the addition of carbon black to the matrix decreases the creep compliance due to the significant interaction between the fiber and matrix, which leads to the increased modulus
Summary
The fast development of smart sensors has contributed to smart elastic strain sensors. Carbon black (CB) is used as a filler and conductive particle in polymer materials. Several researchers have investigated the effect of the addition of various inorganic fillers such as carbon black, carbon nanotubes (CNTs) [16, 17], SiO2 [18] Nanoclay [19] on the mechanical and electromechanical study of composites with conductive fillers. D’Aloia et al [21] investigated that graphene’s addition leads to an increase in the graphene-thermosets polymer’s electromechanical and mechanical properties graphene concentration increase, the graphene-polymer composite undergoes an insulator-to-metal transition due to the presence of conductive filler inside the matrix. It is reported that the addition of carbon nanotube to SEBS elastomer could increase electrical resistance. Yang et al [23] investigated the resistance response of
