“…However, the thermal conductivity of PI itself is in the range of 0.1–0.35 W/mK, which limits its application in the field of heat dissipation. Therefore, some modified fillers are usually introduced, for example, ceramic fillers, such as SiO 2 , aluminum nitride (AlN), and boron nitride (BN) with high thermal conductivity in the range of 100 and 1000 W/mK [ 144 , 145 , 146 ]; metal fillers, such as Al, Cu, and Ag [ 147 , 148 ]; and carbon-based fillers, such as carbon fiber (CF), CNT, and graphene [ 149 , 150 ]. Combined with functional fillers, PI composites with high thermal conductivity endow their reliability and ductility in communication, automotive, and aerospace applications.…”

Polyimide (PI) is one of the most dominant engineering plastics with excellent thermal, mechanical, chemical stability and dielectric performance. Further improving the versatility of PIs is of great significance, broadening their application prospects. Thus, integrating functional nanofillers can finely tune the individual characteristic to a certain extent as required by the function. Integrating the two complementary benefits, PI-based composites strongly expand applications, such as aerospace, microelectronic devices, separation membranes, catalysis, and sensors. Here, from the perspective of system science, the recent studies of PI-based composites for molecular design, manufacturing process, combination methods, and the relevant applications are reviewed, more relevantly on the mechanism underlying the phenomena. Additionally, a systematic summary of the current challenges and further directions for PI nanocomposites is presented. Hence, the review will pave the way for future studies.

“…Polyimide is a high-performance polymer which is widely employed in aerospace and military fields due to its exceptional properties such as high heat resistance, low electrical conductivity, and intrinsic mechanical strength. It is generally synthesized via polycondensation between dianhydride and diamine [1][2][3][4][5][6]. However, the production of its monomers still relies on petroleum-based chemicals, which are associated with serious environmental issues and an energy crisis.…”

The development of renewable polymers as alternatives to the petroleum-based ones has received significant attention due to the increasing depletion of fossil oil and the associated environmental concerns. In this study, a semi-biomass-based polyimide (PI) film was successfully synthesized, using biomass-derived furfural (HMFA) as one of the raw materials. A two-step approach was first developed for this process: (1) conversion of HMFA to 3,3,4,4-biphenyltetracarboxylic acid dianhydride (BPDA) and (2) polymerization of BPDA with p-phenylenediamine (PPD) to form a PI film. The fabricated PI film demonstrated excellent properties, such as a high thermal decomposition temperature up to 600 °C, a satisfactory glass transition temperature (Tg) exceeding 365 °C, a coefficient of thermal expansion (CTE) of ≈30 ppm/K, a tensile strength greater than 120 MPa, a dielectric constant value below 3.4, a dielectric loss value of less than 0.02, and a 24 h water absorption rate below 0.8%. These performances are comparable to the petrochemical-based PI. This work offers a promising strategy for utilizing biomass-derived materials in polyimide synthesis and would drive a new wave of advancements in polymer science.
