Joule heating treatments of conductive butyl rubber/ceramic superconductor composites: a new way for improving the stability and reproducibility?

Thermomechanical and electrical properties of PDMS/MWCNT composite films crosslinked by electron beam irradiation

“…On the other hand, h r?c had no obvious trend with the MWCNT content in the composite films within the experimental error, demonstrating that the composite films have similar electric power efficiency, regardless of the MWCNT content. In any event, the s g , h r?c , and s d values of the composite films were found to be far lower than the ones for inorganic filler-reinforced polymer composites reported in literatures [26,27]. It means that the EB-crosslinked PDMS/MWCNT composite films exhibit unusually rapid temperature responses to applied voltages as well as high electric heating efficiency requiring relatively low electric energy to maintain the maximum temperatures.…”

“…In order to characterize the electric heating behavior of the composite films associated with temperature responsiveness and energy efficiency at different applied voltages, the temperature versus time curves in Fig. 9 are divided into three sections: the temperature growth section (0-30 s), the steady-state temperature in equilibrium (30-180 s), and the temperature decay (cooling) section (180-240 s) as being described in previous papers [26][27][28]. For the first section, the time-dependent temperature growth can be expressed empirically as…”

Electrical response and functionality of polymer matrix-titanium carbide composites

“…Composite systems consisting of a polymer matrix and conductive particles of titanium carbide have been considered as a novel class of smart materials, because of their ability to switch from negative to positive temperature coefficient of conductivity [7][8][9]. Negative temperature coefficient of conductivity (NTCC) is useful in applications such as selfcontrolled heaters, current limiters, sensors, thermistors and over current protectors, while it is considered as detrimental in cable engineering [10]. On the other hand, positive temperature coefficient of conductivity (PTCC) is important in electromagnetic shielding and in antistatic materials [11,12].…”

Characterization and electrochemical properties of conducting nanocomposites synthesized from p-anisidine and aniline with titanium carbide by chemical oxidative method

“…21 Organic-inorganic hybrid materials, which combine excellent 22 performances of the two materials, are extremely innovative, and 23 such materials promise new applications in many fields, such as 24 electronics, optics, electrochemistry, supercapacitor, mechanics 25 and biology [7][8][9][10]. Any organic-inorganic hybrid materials can be 26 obtained by intercalative reactions of layered solids based on 27 self-assembly approaches [11][12][13][14]. 28 Recently, on the basis of conducting polymers and inorganic 29 nanoparticles, the nanocomposites have attracted attention as it 30 seems to be the potential route to improve the performance of 31 materials in devices.…”
