Experimental Images and Videos of Foam Stability (Half-life)

The experimental data obtained in this project is the thermal stability data of various foams measured using the setup established at Temple University during this study. The setup is installed with a portable digital camera which can take images and videos of foam evolution at a given pressure and temperature condition. Consequently, the half-life data was recorded from the images/videos, which are used as a measure of the thermal stability for foams. Over the 3 years of this project, four different surfactants and five different stabilizing agents were studied. The surfactants are, Alfa Olefin Sulfonate (AOS), Sodium Dodecyl Sulphate (SDS), Tergitol (NP-40), and Cetyltrimethylammonium chloride (CTAC). The stabilizing agents are, guar gum, bentonite clay, crosslinking agents, silicon dioxide nanoparticles (60 to 70nm), and graphene oxide dispersions. Foam stability was evaluated at different temperatures between 100C and 200cC, while the foam generation pressure varied between atmospheric pressure (14.7 psi) and 1000 psi.

本项目获取的实验数据为各类泡沫的热稳定性数据，该数据通过本研究期间在天普大学（Temple University）搭建的实验装置测得。该实验装置搭载便携式数码相机，可在指定压力与温度条件下拍摄泡沫演化过程的图像与视频。随后从上述图像/视频中提取半衰期数据，并将其作为泡沫热稳定性的评价指标。本项目历时三年，共研究了四种不同的表面活性剂与五种不同的稳定剂：四种表面活性剂分别为α-烯烃磺酸盐（Alfa Olefin Sulfonate, AOS）、十二烷基硫酸钠（Sodium Dodecyl Sulphate, SDS）、Tergitol（NP-40）以及十六烷基三甲基氯化铵（Cetyltrimethylammonium chloride, CTAC）；五种稳定剂分别为瓜尔胶、膨润土、交联剂、二氧化硅纳米颗粒（粒径60~70nm）以及氧化石墨烯分散液。实验在100℃至200℃的不同温度下评估泡沫稳定性，泡沫生成压力则在常压（14.7 psi）至1000 psi之间变化。采集的图像以.jpg格式存储，视频以.avi格式存储。
