钛酸纳米管涂层改善竹材热稳定性能的研究
|
摘要
本文通过水热合成法制备了钛酸纳米管(Titanate Nanotubes, TNTs),并利用硅烷偶联剂(γ-氨丙基三乙氧基硅烷)对其进行改性.然后以硅烷偶联剂为阳离子聚合物,木质素磺酸钠为阴离子聚合物,通过层层自组装的方式将TNTs以纳米膜的形式包覆在竹材表面,借以增强竹材热稳定性.实验结果表明:经自组装,TNTs形成纳米膜包覆在竹材表面,形成保护层,使得竹材热稳定性获得显著提升,且随着组装层数的增加而进一步上升.在N2氛围下,竹材热分解温度由239. 8℃(LBL-0)分别上升至265. 1℃(LBL-3),272. 4℃(LBL-6),286. 6℃(LBL-9)及289. 6℃(LBL-12),残余质量由22. 4%上升至22. 9%(LBL-3),27. 7%(LBL-6),29. 6%(LBL-9)及32. 6%(LBL-12);在O2氛围下,竹材热氧化温度同样有显著提升,由238. 4℃(LBL-0)上升至280. 6℃(LBL-12).
In this paper, TNTs(Titanate Nanotubes) were prepared via hydrothermal synthesis method and modified by using silane coupling agent(gamma-ammonia propyl triethoxy silane). Then the modified TNTs, were coated on the surface of bamboo wood to enhanced its thermal stability via layer-by-layer self-assembly technology, by using sodium lignosulphonate as anionic polymer and silane coupling agent as cationic polymer. The results showed that the thermal stability of bamboo wood significantly enhanced when TNTs coated on the surface and formed a protective layer. And it would further improved with the increased number of layer. Under the atmosphere of N2, the thermal decomposition temperature of bamboo wood increased from 239. 8 ℃(LBL-0) to 265. 1 ℃(LBL-3), and 272. 4 ℃(LBL-6), 286. 6 ℃(LBL-9), and 289. 6 ℃(LBL-12), and the residual quality rose from 22. 4% to 22. 9%(LBL-3), 27. 7%(LBL-6), 29. 6%(LBL-9) and 32. 6%(LBL-12).Under the atmosphere of O2, the thermal oxidation temperature of bamboo wood also enhanced obviously, from 238. 4 ℃(LBL-0) to 280. 6 ℃(LBL-12).
