“…FTIR spectra of FGO in Figure A show that the characteristic absorption peaks located at 1620 and 3415 cm −1 are corresponding to CC band and OH groups, respectively, which is consistent with that of rGO . Additionally, compared with rGO, a new peak appeared at 1070 cm −1 in FGO, which is indexed to the stretching vibration of the CF bond . The above analyses imply that FGO was successfully fabricated via hydrothermal treatment.…”

Novel polyimide/fluorinated graphene oxide (PI/FGO) nanocomposites with outstanding mechanical, thermal, and tribological properties were obtained using FGO nanosheets which were successfully fabricated by simple hydrothermal reaction. FGO exhibited distinguished interface adhesion with PI matrix due to covalent bonds, resulting improved mechanical and wear resistance of PI/FGO nanocomposites. Wherein, PI/FGO‐0.5 nanocomposite demonstrated conspicuous tribological performance accompanied with 33.1% decrease of friction coefficient and 80.8% reduction of wear rate compared with pure PI under dry friction. Notably, PI/FGO nanocomposites manifested better wear resistance under seawater than that under dry friction, illustrating its great potentiality as high wear‐resistant material suitable for ocean environment.

Low dielectric constant and low dissipation factor, superior hydrophobicity, excellent thermal and mechanical property, and good optical performance are desired for advanced electronic packaging of fan-out wafer level package (FO-WLP). An effective approach was introduced to fabricate novel fluorinated graphene/polyimide(FG/PI) nanocomposite films in this paper. FG nanosheets exhibit excellent dispersion in the PI matrix due to their high surface area with some oxygen-containing functional groups, and individual graphitized planar structure. Besides, the effects of the addition of FG on the dielectric, optical, mechanical, thermal properties as well as the hydrophobicity of the films are investigated with controlled amounts of FG. The dielectric constant and loss can be as low as 2.64 (at 10 6 Hz) and 0.00176 for PI-0.5wt% FG. And with the increase of the loading of FG, the thermal stability (T 5 = 514 C) and mechanical property (tensile modulus = 2.11GPa, tensile strength = 93.23 MPa, elongation at break = 11.60%) has been improved successfully. Besides, the contact angles have been increased from 83 to 92 showing a superior hydrophobicity which is essential for the FO-WLP. Moreover, the incorporation of FG also proved excellent optical performance of 88% transmittance at 550 nm. Therefore, with the excellent comprehensive performance, the as-prepared FG/PI films possess widespread applications in the microelectronics especially in FO-WLP.

Polyimide is a polymer of imide monomers. Polyimide has properties like Thermal stability Good chemical resistance, Excellent mechanical properties, High tensile strength, Lightweight flexible, resistant to heat and chemicals. Polyimide is used in various application like EMI shielding, fuel cell, supercapicator, aerospace etc. Polyimide properties can be increased by adding filler like CNT and graphene. The syntheses of various polyimide nanocomposites including diamines and dianhydrides that have been used to make novel polyimides with unique properties, are reported in this review. Properties of polyimide like thermal properties, electrical conductivity, and mechanical properties by adding CNT and graphene is studied in this review. I.INTRODUCTION In this review Article, particular emphasis is given to the polyimide nanocomposite and its various application. Polyimides have been in mass production since 1955. With their high heat-resistance, polyimides enjoy diverse applications e.g. high temperature fuel cells, EMI shielding material and as supercapacitor material, and as separation membrane. Polyimide is also known as engineering plastic. In last years many work has been done by the scientists on polyimide. Mainly work was done on polyetherimide, polyamideimide, polyesterimide, etc. polyimide belongs to the class of high-temperature polymers with balanced chemical and mechanical properties in addition to superior film-forming properties. Mechanical properties ,electrical properties and thermal stability of polyimide can be improved by adding the filler. By adding the filler or forming of nanocomposites there is drastically change in the properties of polyimide can be noticed by many scientist in their research work . Fillers like CNT, graphene, were used to increase the properties of polyimide. Mainly CNT and graphene is used as filler because of their low loading level [1]. CNTs (Carbon nanotubes) are composed of graphene sheet rolled up. CNTs is of two types SWNT and MWNT. CNTs can be considered as ultimate carbon fibers due to ultra high strength (10 to 100 GPa) and modulus (~1.0 TPa) values alongwith exceptional electrical (104-106 S/cm) and thermal properties (3000-6000W/mK) [2]. The higher intrinsic conductivity and aspect ratio of CNTs (100-5000) compared to carbon black allows the formation of conductive composites at low loading of CNTs due to low percolation thresholds (minimum loading level at which a continuous network of conducting particles is formed) resulting in achievement of better electrical conductivity and electromagnetic response at the same loading level. Graphene is a nanoscale materials based on single/multi-layered 2-D graphene sheets have attracted much attention recently due to its unusual properties [3]. Though composite materials employing carbon-based materials are presently dominated by carbon nanotubes, the intrinsic bundling of carbon nanotubes, impurities from the catalysts and high costs have been hampering their application. It has been proposed that these prob...
