Investigations of structure development, electrical and thermal properties of polyvinylidene fluoride-expanded graphite nanocomposites

Polyvinylidene fluoride‐natural graphite flexible composite films: Formation of graphite nanosheets, electroactive phase, analysis of electrical and thermal properties

“…The details such as grade and MFI of the polymer namely PVDF have been reported elsewhere 2 . N,N ‐dimethylacetamide (DMAc) (AR grade) and N,N ‐dimethylformamide (DMF) (AR grade) have been procured from S.D‐fine chemicals, India.…”

“…Conducting polymer composites (CPCs) are extensively being studied for their promising utilization in diversified applications such as EMI shielding, sensors and actuators, energy harvesting, energy storage, and so forth 1,2 . Further the flexibility, lightweight, low‐cost and easy processibility of CPCs make them attractive candidates for various applications.…”

“…In addition, the authors did not investigate charge transport characteristics in those binary composites. Ramanujam et al 2 have investigated in detail structure development, electrical, and thermal behaviors of PVDF‐expanded graphite (ExGr) nanocomposites by non‐solvent precipitation and solution blending methods. Expanded graphite is synthesized by using perchloric acid as reported by the authors.…”

Nanoclay-based Polymer Nanocomposites for Electromagnetic Interference Shielding

“…The thickness of the EMI shield also affects the absorption mechanism. The potential candidates and alternate to conventional metals as EM shields are conducting polymerbased composites (CPCs) [3,5,6,[12][13][14]. The conducting polymers have low density, lightweight, cost effective and can be used to prepare ultra-thin flexible EMI shield.…”

“…Specifically, this chapter presents a review and summary of recent research and development on the effects of incorporating nanoclays in conducting polymers, with focus towards enhancing the mechanical, thermal, electrical and dielectric properties of the nanocomposites. The CPC-based shield materials are expected to absorb microwaves in X Band (12)(13)(14)(15)(16)(17)(18) and Ku Band (18-27 GHz) part of the EM spectrum. In the first section of the chapter, the EM shielding theory and the basic characteristic that an EMI shielding material should possess are discussed in detail.…”
