摘　　要：研制了纳米颗粒沉积玻璃纤维作为新型聚结材料,考察了分散液浓度、沉积时间和纳米颗粒尺寸等因素对纳米颗粒在纤维表面沉积情况的影响,检测了表面纳米颗粒沉积玻璃纤维的脱水性能。结果显示分散液浓度和浸泡时间对纳米颗粒的沉积情况没有明显影响,但分散液浓度越高,未沉积在纤维表面的SiO_2颗粒越多;颗粒尺寸越小,在纤维表面沉积效果更好;其中经20 nm粒径SiO_2分散液处理的纤维聚结过滤效果最佳。The glass fibers with deposited nano-SiO_2 particles were prepared, which could be used as new type of coalescence materials. The effects of dispersion concentration, deposition time, and size of nanoparticles on the deposition of nanoparticles on the fiber surface were investigated, as well as the dehydration properties of glass fibers were examined. The results showed that the dispersion concentration and immersion time had no obvious effect on the deposition of nanoparticle. However,the higher the dispersion concentration, the more SiO_2 particles did not deposit on the fiber surface; and the smaller the particle size, the better the depositing condition. The fibers deposited with 20 nm SiO_2 particles had the best coalescence and filtration performance.
