High‐performance polyimide film based hybrid nanostructures: Synthesis, characterization, and properties investigation

Abstract

In this research work, multihybrid nanostructures (carbon nanotube-graphene oxide-zinc oxide) based highperformance polyimide (PI) nanocomposites were prepared via in situ polymerization and their properties (morphological, electrical, and viscous behaviors) were investigated. PI of industrial and laboratory grades was used to study their thermal imidization step after addition of various loadings of multihybrid nanostructures. The use of optimum amount of multihybrid nanostructures seems to be useful to overcome the use of higher amount of different conductive fillers to prepare PIbased high-performance nanocomposites for various applications. This study also provides a facile and promising strategy to fabricate multihybrid nanostructured high-performance PI nanocomposites, which can be used as coating materials in various harsh conditions.

Multi-walled carbon nanotubes (MWCNTs) filler effects on some physical properties of PCL/PMMA blend films

“…It con rmed that the adhesion between the MWCNTs and matrix had been signi cantly enhanced via the grafting of polymer from the surface of MWCNT. Particle shape and particle size can also contribute to the observed mechanical response of the composites (21)(22)(23)(24). Their tensile strength, Elastic modulus, and Strain to failure % are given in Table 1.…”

Preparation and Properties of Graphene/ODA-PMDA-NTADA Copolyimide Nanocomposites Based onKH550-modification

“…These materials have been found extensive application in various technical domains such as aerospace, electrical equipment, biological detection, laser, adhesive, coating, and thin films [1][2][3]. However, the comprehensive aromatic structure of PI restricts its subsequent application research due to its insoluble and infusible attributes [4][5][6]. Consequently, numerous structural modifications on linear PI are requisite, including the addition of flexible diamine or dianhydride monomers [7], the synthesis of monomers with new structures (like asymmetric structures and fluorine-containing structures) [8], and the polymerization reaction.…”

Influence of the coupling agent and graphene oxide on the thermal and mechanical behavior of tea dust–polypropylene composites

“…The introduction of nanomaterials (graphene, metal oxide, metal sulfide, etc.) has prompted the development of conducting polymer nanocomposites for emerging applications. In particular, graphene‐based nanocomposites have attracted considerable attention because of their unique properties, including their high thermal conductivity, mechanical stiffness, electronic transport properties, and optical and chemical performance .…”
