摘要
河北涞源斜纤蛇纹石为较小的中孔纳米管材料,通过氮吸脱附法、差热和热重曲线分析法、差示扫描量热分析法和红外光谱分析法,主要分析了其纳米管中管道水特征,明确了管道水作为有效加速剂和载体的作用,对以及对抗拉强度和介电常数的影响。研究表明斜纤蛇纹石纳米管中存在管道水(属于吸附水),去除温度在240℃±,内径为2nm～3nm的纳米管中管道水含量最高,管道水含量与纳米管分散度成反比。
Using the N_2 adsorption, TGA, DTA, DSC and IR,the character of water in the nanotube of clinochrysotile, a kind of natural mesoporous nanotube material with inner diameter of 2 nm^4 nm from Laiyuan,Hebei Province was studied.The results showed that the adsorption water occurring in the nanotubes can be wiped off at around 240 ℃. The water played the role of accelerating agent and carrier and had the effect on the tensile strength and dielectric constant of clinochrysotile nanotubes. Inner diameter and disperse degree of clinochrysotile nanotubes bundle were two key factors to affect the content of the water in the tube.The content of water in the nanotubes with inner diameter of 2 nm to 3 nm reached the highest and the content of water in the tube was inversely proportional to the disperse degree of nanotubes bundle.
