“…The value of remarkably increases as the polymer content increases and reaches the maximum of 45.1 for the polymer content of 20 wt%, which is much higher than the values from others polymer composites. [14][15][16][17] Further increase of polymer content decreases . From the aspect of practical application, the suitable polymer concentration is in the range of 17-22 wt%.…”

“…In order to overcome this problem, varistor materials based on polymer composites, which can be fabricated without sintering, have been studied, such as silicon rubber-SiC, 14 polyethylene-ZnO, 15 polyaniline-ZnO, 16 and polyethylene/polypropylene/polyvinylidene fluoride-Si/Ge. 17 However, these materials have relatively low nonlinear coefficient of about 10, which restricts their practical applications due to low efficiency. In the present work, a polymer/ ceramic composite varistor based on epoxy resin/manganese oxide composite with high flexibility and nonlinear coefficient has been studied.…”

“…Одним з напрямків подолання цього недоліку є розробка на основі полікристал і ч н и х п о р о ш к і в V О 2 п о л і м е р н и х композитів, де в якості матричних матеріалів використовується епоксидна смола [5], поліетилен [6] і політетрафторетилен (тефлон) [7]. У зв'язку з цим розглядаються як перспективні напрямки вдосконалення відомих напівпровідникових приладів і створення елементів та матеріалів з новими функціональними властивостями, шляхом використання наповнювачів з нелінійною електропровідністю, зокрема напівпровідникової варисторної кераміки [8,9] і напівпровідників з ФПМН [10].…”

“…Varistors potentially benefit from the reversible nonlinear I-V characteristic that is observed in polymer composites, including conductive or semiconductive fillers and polymers [5][6][7][8]. Little research has examined varistor-type polymer nanocomposites with high nanomaterial filler concentrations until recently [9][10][11]. The conductivity in nanocomposites is usually described by intrinsiccharge carrier generation, interfacial between grain and grain boundary, and charge carrier injected of electrodes in a high electric field.…”
