Exploitation of Carbon Nanotubes in High Performance Polyvinylidene Fluoride Matrix Composite: A Review

Abstract

Among nanocarbon filler, carbon nanotubes (CNTs) are considered to be an ideal reinforcement due to their miniscule size, and excellent electrical, thermal, and mechanical properties. However, CNTs can be utilized in polymer nanocomposites only if they are homogenously dispersed into polymer matrices. The multi-walled carbon nanotube (MWCNTs) has been concentrated as reinforcement for an important type of thermoplastic polyvinylidene fluoride (PVDF). This review firstly focuses on CNTs modification both by mechanical methods and chemical functionalization to improve their dispersion. Moreover, processing methods for PVDF/CNTs nanocomposite have been discussed. MWCNTs facilitate the electrical conductivity, thermal, rheological and mechanical properties of PVDF.

Hybrid lead-free polymer-based nanocomposites with improved piezoelectric response for biomedical energy-harvesting applications: A review

“…Lead-free piezoceramic particles (BT, KNN) [48-51, 54, 55], metal oxide NPs (ZnO, MgO, TiO 2 ) [19,[56][57][58][59], CNTs [60][61][62][63][64][65], graphene and graphene derivatives such as rGO [27,66,67], hydrated ionic salts [68], nanoclays [69,70], and metal NPs (Ag, Pt) [71,72] have all proven to be highly efficient as nucleating fillers that can induce a polar electroactive phase without applying electrical polarization. By optimizing the concentration and uniformity of the distribution of the fillers in the polymer matrix, superior piezoelectricity and dielectric values are obtained.…”

“…CNTs can be modified by mechanical methods and chemical functionalization. The approaches used for the dispersion of CNTs are described in detail elsewhere [61,108].…”

Observations of a novel strengthening mechanism in HDPE nanocomposites

“…As observed from the results in Figures 2 and 3, the reinforcing efficiency any composite can be attributed to efficient load transfer at the nanofiller-polymer interface. This efficiency may be influenced by the presence of agglomerates [14,30]. A closer analysis of the mechanical results indicates that the underlying nanoscale strengthening mechanism may be governed by microstructural changes due to embedded CNTs in the microstructure.…”

“…Notwithstanding, it is possible to obtain improvement in mechanical properties of polymer composites without surface treatment of the fillers [12,13]. Other well-known techniques used to promote interaction with the matrix include ionic and non-ionic surface functionalization and polymer wrapping [14][15][16][17][18].…”

Mechanical, thermal, conductivity, and electrochemical behavior of poly(vinylidene fluoride)/poly(3,4-ethylenedioxythiophene)/polyaniline-grafted-nanodiamond nanocomposite

“…3 Amalgamation of nanoparticle in PVDF may also enhance thermal, mechanical, and pyroelectric properties of PVDF. 4 Stretching as well as the incorporation of nanofiller in PVDF changes the crystalline form of the sample to b-phase. Nanofillers act as nuclei centers for the crystallization of PVDF.…”
