Fabrication of SiC‐Treated P(VDF‐HFP)‐(BFO‐SO₃H) Composite Films for High Performance Energy Storage Device (HPESD) Applications

Abstract

In this work, ÀSO 3 H functionalized BiFeO 3 (BFO-SO 3 H) is prepared and its utility toward the development of polymer-(BFO-SO 3 H) composites is explored in line with silicon carbide (SiC) as third phase conductive filler, which can be used in the field of high performance electrical storage device (HPESD). Surface functionalization plays a vital role to reduce the agglomeration and improve their surface area for better adhesion with the polymer matrix (polyvinylidene fluoride hexafluoro propylene; P(VDF-HFP)). SiC directly influences the conducting networks of BFO-SO 3 H favoring high electrical properties of the composites. Similarly, the high remanent polarizations of the SiC-treated composites indicate their enhanced ferroelectric behavior as compared to that of untreated one. Thus the SiC-treated polymer-ceramic composites will be more advantageous for HPESD applications than that of untreated one.

On Adaptive Control for Electrical Discharge Machining Using Vibroacoustic Emission

“…By other words, it should be conductive [20]. The conductivity should be assured by conductive nano-sized additives as TiC, ZrC, Nb (2) C [21][22][23], when SiCw or carbon in the form of nanotubes or whiskers are responsible for supporting and improving Technologies 2018, 6, 96 2 of 18 mechanical properties [24,25]. It makes the questions related to ensuring of the uninterrupted electrical discharge machining using in-situ monitoring critical and significant to adapt the electrical parameters of machining and to prevent all undesirable effects during processing.…”
