Fabrication and evaluation of polyamide 6 composites with electrospun polyimide nanofibers as skeletal framework

Electrospun nanofiber reinforced all-organic PVDF/PI tough composites and their dielectric permittivity

“…The remarkable reinforcement of the PVDF/PI composites could be due to the intrinsic superior mechanical strength of aligned co-PI nanofibers and the strong interfacial adhesion between co-PI nanofibers and PVDF matrix (Fig. 1) [15]. Toughness is a useful parameter to access the flexibility of the 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.…”

High‐performance polyimide nanofibers reinforced polyimide nanocomposite films fabricated by co‐electrospinning followed by hot‐pressing

“…Polyimide (PI) is an important class of high‐performance polymer with excellent mechanical properties and thermal stability. The preparation and application of various electrospun PI nanofibers have been investigated by Hou and coworkers . For example, Chen et al .…”

Preparation and Characterization of Pure Organic Dielectric Composites for Capacitors

“…Reported data were the average value of at least three individual measurements. corresponds to the C=O asymmetric stretching vibration, 1720 cm −1 corresponds to the C=O symmetric stretching vibration, 1370 cm −1 corresponds to the C-N-C stretching vibration, and 720 cm −1 corresponds to the C=O bending vibration [26][27][28]. Furthermore, the absence of the characteristic absorption bands of PAA at approximately 1660 cm -1 corresponds to the amic acid C=O symmetric stretching vibration and 1535 cm -1 corresponds to the amide C-N asymmetric stretching vibration indicates complete imidization in the resulting composites [29,30].…”
