Chapter 1 -- Basics of Polymers and Polymer Nanocomposites as Dielectric Materials
Li, Bin; Zhong, Wei-Hong (Pan Stanford Publishing Pte. Ltd., 2017)When the polymer has a flexible chain structure, this polymer could develop into highly ordered crystal structures. However, for polymer materials, it is very difficult to achieve 100% crystallinity. Thus, semi-crystalline ... -
Chapter 2 -- Theoretical Analysis of Dielectric Relaxation in Polymer Nanocomposites
Li, Bin; Zhong, Wei-Hong (Pan Stanford Publishing Pte. Ltd., 2017)Figure 2.1 Schematic illustration of a dipole.According to Fig. 2.1, it is obvious that magnitude of a dipole is determined by both the separation distance (a) between positive and negative charges and the amount of charges ... -
Chapter 3 -- Perovskite Ceramics and Their Polymer Nanocomposites
Li, Bin; Zhong, Wei-Hong (Pan Stanford Publishing Pte. Ltd., 2017)Many inorganic ceramics have large permanent dipole moment, due to their chemical compositions and crystal structures. They typically exhibit very high dielectric permittivity up to a few thousands, in contrast to the low ... -
Chapter 4 -- Graphitic Nanomaterials and Their Polymer Nanocomposites for Dielectric Applications
Li, Bin; Zhong, Wei-Hong (Pan Stanford Publishing Pte. Ltd., 2017)The large difference in the electrical conductivity between insulating polymers and highly conductive nanomaterials is believed to be responsible for strong interfacial polarization in conductive polymer nanocomposites. ... -
Chapter 5 -- Poly(Vinylidene Fluoride) in Dielectric Nanocomposites
Li, Bin; Zhong, Wei-Hong (Pan Stanford Publishing Pte. Ltd., 2017)The commercial plastic dielectric films today are dominated by those made of polypropylene and polyester because of their high electrical breakdown strength, low dielectric loss, self-healing ability, low cost, etc. However, ... -
Chapter 6 -- Copolymers in Dielectric Polymer Nanocomposites
Li, Bin; Zhong, Wei-Hong (Pan Stanford Publishing Pte. Ltd., 2017)In Chapter 5, we discussed poly(vinylidene fluoride) (PVDF) as a popular matrix material for nanocomposites with high dielectric performances. In particular, because of its high polarization, piezoelectricity, and ... -
Chapter 8 -- Hybrid Polymer Nanocomposite Systems
Li, Bin; Zhong, Wei-Hong (Pan Stanford Publishing Pte. Ltd., 2017)Dispersion, distribution, and surface properties of different nanomaterials are among the most important factors that affect properties and functionalities of polymer nanocomposites. Therefore, a great amount of effort has ... -
Ion-induced effective control of morphologies of soy protein biocomposites
Eyler, Allen; Wang, Yu; Liu, Tian; Li, Bin; Zhong, Wei-Hong (Springer International Publishing AG, 2015-04)Soy protein isolate (SPI) has received immense research attention recently for its potential use in biocomposites. As a protein material, SPI is highly complex; it possesses four levels of structure arising from many types ... -
Segregated polymeric nanocomposites with tunable three-dimensional network of nanoparticles by controlling the dispersion and distribution
Geng, Bing; Wang, Yu; Li, Bin; Zhong, Wei-Hong (Royal Society of Chemistry, 2014-10-09)A tunable three-dimensional network of nanoparticles was for the first time realized in a segregated polymeric nanocomposite by controlling the dispersion and distribution of nanoparticles in an emulsion system. The results ...
