Stretchable Porous Carbon Nanotube‐Elastomer Hybrid Nanocomposite for Harvesting Mechanical Energy

Abstract

A stretchable porous nanocomposite (PNC) is reported based on a hybrid of a multiwalled carbon nanotubes network and a poly(dimethylsiloxane) matrix for harvesting energy from mechanical interactions. The deformation-enabled energy-generating process makes the PNC applicable to various mechanical interactions, including pressing, stretching, bending, and twisting. It can be potentially used as an energy solution for wearable electronics.

Effect of Mussel‐Inspired Poly(Dopamine)‐Functionalized Carbon Nanotubes/Graphene Nanohybrids on Interfacial Adhesion of Soy Protein‐Based Nanocomposites

“…When compared with the neat SPI film, the EB of SPI/G/PDCNTs film was significantly increased from 90.77% to 162.18%, which was due to the enhanced interfacial interactions and adhesion effect between the PDCNTs and SPI matrix . When compared with the SPI nanocomposite film in our previous work , the TS and EB of SPI/G/PDCNTs film were significantly increased by 35.51 and 86.11%, respectively, suggesting the simultaneously improved strength and toughness. Therefore, these results demonstrated that the homogeneous dispersion of PDCNTs and the efficient stress transfer between the SPI chains and filler percolating network could promote the dissipation of fracture energy and lead to a significant improvement in the mechanical properties of the SPI‐based hybrids.…”

“…After integrating the PDA‐modified CNTs, the SPI/G/PDCNTs film became less opaque and more transparent. This result indicated the improved dispersibility of the CNTs in the polymer matrix, which was attributed to the self‐polymerization of oxidative PDA onto the surface of CNTs . The UV–vis light transmittance spectra were carried out to analyze the optical barrier properties of the resultant SPI‐based hybrid films.…”

“…Recently, significant scientific efforts have been focused on the surface modification of nanomaterials to improve the interfacial properties of polymer nanocomposites . Cheng et al prepared a GO‐based nanocomposite with superior toughness and high conductivity by applying 10, 12‐pentacosadiyn‐1‐ol (PCDO) to covalently cross‐link GO nanosheets.…”

“…In addition, the poor dispersion of carbon‐based materials in aqueous media may lead to irreversible aggregation in the system. In our previous work, we reported a method to assemble the negative charged graphene nanosheets and positive charged polyethyleneimine (PEI)‐modified cellulose nanocrystals to enhance the interfacial adhesion of the SPI‐based films . However, this fabricating method is relatively complicated, and the PEI is a toxic chemical, which is harmful to the environment.…”

A novel method to prepare homogeneous biocompatible graphene‐based PDMS composites with enhanced mechanical, thermal and antibacterial properties

“…However, the relatively weak mechanical property often limits its application. In order to overcome this problem, many inorganic fillers, for example graphene , carbon nanotubes (CNTs) , silicone , Au nanoparticle and so on are used to prepare PDMS nanocomposites. Among these fillers, graphene has caught our eyes on account of its unique structure and prominent properties such as large specific surface area, high tensile modulus and so forth.…”
