Nanofiller Dispersion in Polymer Dielectrics

“…Examples of applications are pulsed power and power conditioning applications for electrical grid. As a response, different methods and material approaches were studied to achieve the requirements [5,6]. For example, a homogeneous dispersion of ferroelectric BaTiO 3 particles were prepared in polypropylene with an in-situ polymerization process [3].…”

“…One of the approaches to achieve high energy densisty has been the novel dielectric materials designed using nanoengineering and nanotechnology [4,5]. These high performance nanodielectric composites have become one of the strategic building blocks in material technology in the last decade.…”

Breakdown Strength of TiO2/Epoxy Nanocomposites Using Centrifugation Agglomerate Removal

“…The short-term breakdown strength (BDS) of the bulk rather than the surface of epoxy NCs is reported to be higher than that of unfilled epoxy resin (ER) in breakdown tests using recessed electrodes or McKeown electrodes [9][10][11][12]. The higher the relative permittivity of nanofiller, such as MgO and TiO 2 , the deeper the traps around it, which may further increase the breakdown strength [13].…”

“…Whether the nanofillers are formed in polymers by using the sol-gel process or if their surfaces are treated by chemical treatment to be monodispersed, or if they are directly compounded to the polymer with high shear force, some agglomerates always remain during mass production of epoxy NCs. Although agglomerates can act as defects, reducing the short-term BDS of epoxy NCs [11][12][13][14], the mechanism behind how agglomerate size affects the BDS is not understood. To optimize the manufacturing of epoxy NCs, it is necessary to clarify the relationship between the agglomerate size and BDS enhancement.…”

Enhancement of Mechanical Properties of Polyamide Hexaglycol by Dispersion of TiO2 Nanofiller

“…), nonmetal oxide (SiO 2 ), and others (SiC) [9][10][11][12][13][14]. The selection of nanoparticle filler depends on the desired thermal, mechanical, and electrical properties of the nanocomposites [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. The aim of this research was to study the effect of the weight percent of TiO 2 anatase nanofiller particles on the hardness, tensile strength, and creep at room termperature of nano TiO 2 / PAHG polymer matrix composite.…”
