Rigid‐rod polymeric fibers
Han Gi Chae, Satish Kumar
SJR Q2Journal of Applied Polymer Science

Abstract This paper traces the historical development of high temperature resistant rigid‐rod polymers. Synthesis, fiber processing, structure, properties, and applications of poly( p ‐phenylene benzobisoxazole) (PBO) fibers have been discussed. After nearly 20 years of development in the United States and Japan, PBO fiber was commercialized with the trade name Zylon® in 1998. Properties of this fiber have been compared with the properties of poly(ethylene terephthalate) (PET), thermotropic poly

SJR Q1ACS Applied Materials & Interfaces

Poly(vinylidene fluoride) (PVDF)/graphene oxide (GO) nanocomposite fibers were dry-jet wet spun at the GO concentrations of 0, 1, and 2 wt % with respect to the polymer. The as-spun fibers were drawn in the draw ratio (DR) range of 2-6.5, and the correlation between the PVDF chain conformation and the mechanical properties of the fibers upon drawing has been studied by two-dimensional correlation spectroscopy of Fourier-transformed infrared, wide-angle X-ray diffraction, differential scanning ca

SJR Q1Advanced Energy Materials

Abstract Thermoelectric (TE) technologies offer promising means to enhance fossil energy efficiencies by generating electricity from waste heat from industrial or automobile exhaust gases. For these applications, thermoelectric modules should be designed from the perspective of system integration for efficient heat transfer, system simplification, and low processing cost. However, typical thermoelectric modules manufactured by traditional processes do not fulfil such requirements, especially for
