Physicochemical properties and kinetic analysis for some fluoropolymers by differential scanning calorimetry

Thermal Degradation Behavior and Kinetics of aged TNT-based Melt Cast Composition B

“…The T onset and T max values shifted towards the upper range of temperatures with increasing heating rate. A similar effect of shift in the peak temperature has been reported by many researchers for different types of energetic compounds, including explosive formulations [25]. This indicates that the peak temperatures of the RT 2 and RT 3 samples are not changed significantly after prolonged natural ageing periods of 20 and 32 y, respectively, compared to that of a fresh sample.…”

“…where g(α) is the integral reaction model which is reported in the literature [24][25][26]. The activation energy for constant conversion is determined from the linear slope of ln(ϕ/T α 2 ) versus 1/T α at different heating rates.…”

A Bioinspired Artificial Injury Response System Based on a Robust Polymer Memristor to Mimic a Sense of Pain, Sign of Injury, and Healing

“…f) Endurance test of the FK-800 memristor with 10 6 cycles that switch between the "on" and "off" states; the testing on and off voltage pulses applied were 4.5 and 0.2 V with a pulse width of 0.5 ms pulse and pulse interval of 2 ms. g) Comparison of the endurance of the high-performance organic/polymer memristors reported in literature. [41][42][43][44][45][46][47][48] switching behavior and low cycle-to-cycle variability. Due to the dynamic nature of the switching process, the threshold voltage is not fixed, but can be affected by the characteristics of the bias, such as sweep rates.…”

“…[37,45] To overcome one of the key challenges for organic memristors (poor endurance) and reliably emulate nociceptive behaviors, we design a new, flexible, and robust diffusive memristor based on a copolymer composed of chlorotrifluoroethylene (CTFE) and vinylidene fluoride (VF 2 ), known as FK-800. FK-800 is selected due to its high degradation temperature, low thermal expansion coefficient, and low elastic modulus, [46,47] all of which is expected to help maintain structural stability under local heat loads associated with electric switching. Silver (Ag) electrode is used as the active diffusion source, and platinum (Pt) as the counter electrode.…”

Improvement of Interfacial Properties Between Cis‐1,4‐polybutadiene Rubber and HMX Crystal

“…In PBX explosives, CÀ H polymer, CÀ F rubber and polyurethane elastomer are commonly used [22][23][24][25] . Cis-1,4-polybutadiene rubber(BR) is one of the CÀ H binders, but it has weak interfacial interaction with HMX due to its lack of active groups that interact with nitro groups.…”
