Progress in Preparation of Phenolic Fibers by Electrospinning

Abstract

Phenolic fiber is a versatile material. This article focused on introduction of the progress of generating phenolic fibers using solution electrospinning method and its applications, as well as the trail exploration of preparing phenolic fibers by melt electrospinning. For the research on preparation of phenolic fibers using solution electrospinning, researchers added polymers or additive agents to adjust the viscosity and electrical conductivity of the spinning solution. Then they cured and carbonized the electrospun fibers to reach their varied aims. After these two processes, the brittle nature of the phenolic fibers has been greatly changed. What’s more, the modification makes it easier to be dealed with in the analysis tests and be more suitable to be applied as adsorbent materials, nonconductive materials, and flexible materials.

Thermosetting Phenolic Resin-Derived Activated Carbon Fibers for Volatile Organic Compound Adsorption: Electrospinning, Preoxidation, and Carbonization

“…Thermoplastic resin (also named novolac) is conducive to melt spinning, but the fibers must be treated with a curing agent afterward. This cumbersome procedure probably emits extra contaminants such as formaldehyde and hydrogen chloride. , On the contrary, although thermosetting resin (also named resole) cannot be melt-spun, it can be easily heat-set in the postspinning process called preoxidation or curing, which is fairly conducive to electrospinning. With the help of an electric field, the spinning solution containing resole forms a Taylor cone, stretching and splitting.…”

Fabrication and Compressive Properties of Porous Ti6Al4V Alloy with Elongated Pores for Biomedical Application

“…Porous titanium and its alloys are believed to be promising biomaterials for load-bearing application because of their high biocompatibility, specific strength and excellent corrosion resistance [1,2]. In the past decades, great attention has been paid to the mechanical compatibility of titanium and its alloys [3][4][5]. Mechanical incompatibility such as mismatch of Young's modulus between natural bone (less than 30 GPa) and solid titanium (110 GPa) can result in bone resorption and implant loosening due to "stress shielding" effect [6][7][8].…”
