Fabrication and Surface Modification of Macroporous Silica Fibers by Electrospinning for Super Adsorbent of Oil
Hoai Han Nguyen, Thi Thu Hien Nguyen, Young-Sang Cho
Korean J. Met. Mater. 2022;60(10):732-743.   Published online 2022 Sep 29
DOI: https://doi.org/10.3365/KJMM.2022.60.10.732

Abstract
Silica fibers were fabricated by sol-gel reaction and an electrospinning process. A high voltage source of electricity was applied to the prepared spinning solution to form the fibers. Macroporous silica fibers were prepared using polystyrene (PS) nanospheres as templates after calcination. The pore size could be controlled by adjusting the..... More

Korean J. Met. Mater. 2021;59(2):99-112.   Published online 2021 Feb 5
DOI: https://doi.org/10.3365/KJMM.2021.59.2.99
Abstract
In this study, silica aerogel particles were synthesized from emulsion droplets as micro-reactors at room temperature under ambient pressure. An economical precursor, sodium silicate, was used as the starting material for silica, and an emulsification technique was applied to form droplets in continuous phase. By controlling the composition of the... More
