Abstract

Nylon is a biocompatible thermoplastic polymer that is well known for its excellent fracture resistance, making it suitable for fabricating fiber-reinforced composite (FRC)-based dental bridges. FRC is widely used in dentistry. This study aimed to investigate the structural and morphological characteristics of the nylon 6 fiber prepared using five different weights of nylon 6 dissolved in formic acid. The nylon 6 fiber was successfully fabricated via a simple wet spinning method using water as a coagulant. The fiber was then characterized using Fourier transform infrared (FTIR) spectroscopy, optical microscopy, and scanning electron microscopy. FTIR spectroscopy confirmed the presence of nylon 6 characteristics in the fiber in the form of N–H and C=O groups at a specific wave number. The differences in the diameter and morphological shape of the fiber were attributed to the nylon 6 different concentrations. Furthermore, the nylon 6 fiber can be used to produce cost-effective products and realize suitable characteristics for use as an alternative to traditional materials for fabricating direct dental bridges.

Abstract

The lithium-ion battery has gained popularity among other secondary batteries for portable electronic devices and electric vehicle applications, especially the LiNi1/3Co1/3Mn1/3O2 or NMC111, considering its well-balanced configuration resulting in stable and safe electrochemical performance. NMC111 has been successfully prepared using a coprecipitation process at calcination temperatures from 800 to 950°C. The physical characteristics were investigated using X-Ray Diffraction (XRD), Scanning Electron Microscopy-Energy Dispersive Spectroscopy (SEM-EDS), and Particle Size Analysis (PSA). The XRD patterns showed the rhombohedral single phase for all calcination temperatures. Meanwhile, higher calcination temperatures offer higher degree of crystallinity, lower intensity ratio and more undesirable cation mixing. The particles with a uniform rectangle or pyramid shape are observed at the calcination temperature range from 800 to 900°C. However, bigger submicron particles with a rectangle or pyramid shape are detected at a higher temperature (950°C). The SEM-EDS mapping shows the homogeneity composition for all variation calcination temperatures. PSA analysis showed that calcination temperature at 800 and 850°C gives the particle less than 400 nm suggesting a potential material for a cathode of lithium-ion batteries.
