“…Advanced techniques such as transmission electron microscope (TEM), atomic force microscope (AFM), and raman spectroscopy have been utilized to determine chain alignment in nanofibers . Hou and Jiang et al concluded that thinner nanofiber has higher molecular orientation as against thicker nanofiber simply because molecules will have space to randomly locate themselves higher diameter fiber . Naraghi et al found relation between collection distance and molecular orientation with longest collecting distance offering orientation factor of 50% as against 21‐22% for shortest collection distance .…”

Electrospinning has by far proved to be the most successful method to spin high aspect and surface area to volume ratio nanofiber for multidisciplinary applications. Its application, however, as reinforcement in fiber reinforced polymer matrix composites (FRPC's) started from interlaminar fracture toughness improvement through interleaving. Since then, its usage both in short fiber and nonwoven mat formation has been phenomenally increased to tailor mechanical properties. This review paper focuses on application of nanofiber in multiscale reinforced epoxy matrix composites for mechanical performance. After a brief overview of electrospinning and spinning parameters, it presents a case for nanofiber as reinforcement with attendant mechanisms to develop insight into nanocomposite performance. Next, it summarizes and shares findings of studies, carried out in last 10 years, seeking to enhance tensile, flexural, interlaminar toughness, impact, and fatigue properties of epoxy composites through electrospun nanofiber reinforcement. Finally, it presents a perspective to gain headways in nanofiber reinforced FRPC's research through a variety of processing and material variables.

In this study, we have developed a facile and effective method for fabricating polyimide (PI)-based nanocomposites incorporating octadecylamine (ODA)-functionalized graphene oxide (ODA-fGO) nanosheets. ODA-fGO sheets exhibit superior dispersibility and compatibility with the PI matrix and are successfully obtained through a chemical reaction between graphene oxide (GO) and ODA. The PI-based composites of various loading content of ODA-fGO sheets were prepared via in situ polymerization and thermal imidization process. The mechanical and electrical properties of the PI/ ODA-fGO composites were significantly improved relative to pure PI because of the excellent dispersion of ODA-fGO and the adequate compatibility between fillers and the PI matrix. A 40.7% increase in tensile strength and a 95.5% improvement of Young's modulus were observed for the 3 wt% ODA-fGO (PI/3 wt% ODA-fGO) loading content composite. The electrical and thermal conductivity of PI/3 wt% ODA-fGO was 3.8 Â 10 À2 S m À1 and 0.468 W m À1 K À1 , respectively, which is more than 10 11 times and almost 3 times higher than that of pure PI. The reported approach provides an effective strategy for developing high-performance and multifunctional polymer-based composite materials.

“…Previous work found that the electrospun PI nanofibers possessed excellent mechanical strength [13], superior thermal stability [14], and super high toughness [13], which made them excellent candidates as reinforcements [15,16] and the layer-by-layer hot pressing can improve the uniformity and reduce the porosity of polymer-based composites [17][18][19]. Therefore, in this work, we choose high performance electrospun copolyimide (co-PI) nanofibers as reinforcement and high dielectric performance PVDF as matrix to prepare nanofiber reinforced all-organic composites.…”
