摘要/Abstract

摘要： 在纯溴化锂溶液中加入纳米微粒或分散剂,对比测试其与纯溴化锂溶液的表面张力和沸腾温度的数据,并从所用分散剂的分子结构和纳米微粒的尺寸及外部轮廓的角度出发,定性推测不同种类分散剂及纳米微粒对溴化锂溶液表面张力和沸腾温度的影响.试验发现,添加分散剂溶液的表面张力明显降低,其沸腾温度也相应减小;固体纳米微粒因其填充加热表面凹坑使溶液的沸腾温度有所升高.对于加入纳米微粒及其分散剂的溴化锂溶液,溶液表面张力衰减的正效应因素和纳米微粒填充凹坑的负效应因素的耦合影响将对其沸腾温度产生重要影响.

Abstract: Surface tension and boiling temperature were determined with a contrastive experimental method for LiBr aqueous solutions without and with nano-particles or dispersants added in a same quantity of recipe. The influence of different dispersants and nano-particles on properties of LiBr aqueous solution was conjectured and analyzed qualitatively through the molecular structure of dispersant and the external contour and size of nano-particles. It is found experimentally that the surface tension of solution reduces significantly with dispersants added and its boiling temperature decreases correspondingly. The boiling temperature is increased with nano-particles added because the particles will fill the micro-pits on the heating surface. The boiling temperature of LiBr aqueous solution added with nano-particles and its relevant dispersants have a great influence on the positive effect of lower surface tension and negative effect that nano-particles fill the pits.

Key words: nano-particles, dispersant, LiBr aqueous solution, surface tension, boiling temperature
