졸-겔법에 의한 Silica섬유의 제조

Preparation of Silica Fibers by the Sol-Gel Process

초록

Si(OC₂H₅)₄-H₂O-Alcohol-HCl게 용액을 출발물질로 하여 졸-겔법에 의해 silica 섬유를 제조하였다. 이 때 모든 조성의 용액이 방사성을 나타내는 것이 아니므로, Si(OC₂H₅)₄에 대한 H₂O, alcohol, HCl의 몰비를 변화시켜 각 용액의 섬유인상 가능성을 조사하였다. 용액의 방사성을 나타내는데 있어 가장 중요한 인자는 Si(OC₂H₅)₄에 대한 H₂O의 몰비이며, 이 몰비가 3이하인 용액에서만 방사성을 나타내었다. 제조된 silica섬유의 단면은 대부분 타원형이었으며, H₂O/Si(OC₂H₅)₄ 몰비가 3인 경우에서만 원형구조를 보였다.

Silica fibers were prepared by the sol-gel process from Si(OC₂H₅)₄-H₂O-alcohol-HCl solution as a starting material. Various factors, such as the molar ratios H₂O, alcohol and HCl to Si(OC₂H₅)₄, were investigated in order to find appropriate experimental conditions for the spinnability of the solution. The most important factor determining the spinnability of the solution was the molar ratio of H2O to Si(OC₂H₅)₄ in the solution. The solutions with H₂O/Si(OC₂H₅)₄ ratios less than about 3 showed a marked spinnability just before gelling. Most silica fibers showed the elliptical cross sections except that prepared from the solution with H₂O/Si(OC₂H₅)₄ molar ratio 3, which had a circular cross-section.
