Abstract

In this study, mesoporous SiO nanoparticles (MSNs) were synthesized a sol-gel method and modified with (3-chloropropyl) trimethoxysilane to make them hydrophobic (MMSNs). The material was characterized SEM, TEM, FT-IR, DLS, BET and contact angle measurements. The MMSNs have good foam stability, so that the foam properties of the added particles have been increased by 38.4% in an oil/SDS solution. Simultaneously, it becomes a promising material for foam stabilization in order to enhance the oil recovery because it is bio-compatibile and environment friendly. Also, it provides a novel application-stable foam for mesoporous materials.

摘要

在本研究中，采用溶胶-凝胶法合成了介孔二氧化硅纳米颗粒（MSNs），并用（3-氯丙基）三甲氧基硅烷对其进行改性，使其具有疏水性（MMSNs）。通过扫描电子显微镜（SEM）、透射电子显微镜（TEM）、傅里叶变换红外光谱（FT-IR）、动态光散射（DLS）、比表面积分析仪（BET）和接触角测量对该材料进行了表征。MMSNs具有良好的泡沫稳定性，在油/十二烷基硫酸钠（SDS）溶液中，添加颗粒后的泡沫性能提高了38.4%。同时，由于其具有生物相容性和环境友好性，它成为一种有前景的用于泡沫稳定以提高原油采收率的材料。此外，它为介孔材料提供了一种新型的应用——稳定泡沫。
