Development of 3D-printed electrodes using polyacrylonitrile/ graphene composites for application in polysulfide bromide flow battery

Chemical Engineering and Processing - Process Intensification 2025 Volume 211, Article 110233

The performance of Polysulfide Bromide Flow Batteries (PBS) is depended on the design of the electrodes, which plays a crucial role in ensuring optimal electrolyte distribution and conductivity. These factors are essential for facilitating efficient electrochemical kinetics. This study introduces a novel approach to electrode fabrication using polyacrylonitrile/graphene composites through 3D printing, which enhances structural uniformity and electrical conductivity. The incorporation of reduced graphene oxide, with an electrical conductivity of 23 S/m, into polyacrylonitrile-based electrodes substantially improves their electrical conductivity. Unlike traditional techniques that produce randomly oriented fibers, 3D printing offers precise control over electrode architecture. This enables uniform electrolyte…

Evaluation of a design for a three-dimensional-printed artificial bone structure

Polymer Composites 2023 Volume 44, Issue 12, Pages 8240-8252
I. M. Alarifi

In this work, artificial bones composed of hydroxyapatite (HA)/polyacrylonitrile (PAN) and polylactic acid (PLA) were prepared as a potential replacement for natural bone. The cylindrical specimens included an auxetic system with artificial osteons. HA/PAN and PLA were used to fabricate composite filaments by fused deposition modeling three-dimensional (3D) printing, and the obtained filaments were applied to produce reentrant artificial bone materials. Scanning electron microscopy was used to analyze the scaffold morphology and functional groups. Energy-dispersive X-ray spectroscopy was used for elemental analysis. The compressive properties of the samples were studied to determine the optimal scaffolding prototype. Compressive tests were also…
