Steric stabilization by polymers adsorbed on inorganic particle surfaces is gaining more and more attention in both industry and academia because it plays an important role in stabilizing colloidal dispersions. In this review, basic concepts and some related topics about …

Steric stabilization is the process by which adsorbed nonionic surfactants or polymers produce strong repulsion between particles and droplets in a dispersion.

Steric stabilization is an obstruction among nanoparticles that can prevent the van der Waals attraction. It is essential to obtain strong binding between the polymeric chain and nanoparticles for steric stabilization.

Steric effects are nonbonding interactions that influence the shape (conformation) and reactivity of ions and molecules. Steric effects complement electronic effects, which dictate the shape and reactivity of molecules.

2024年12月25日 · Stearic acid and its mixtures with oleic acid – an unsaturated fatty acid that is liquid at room temperature – were used to produce lipid nanoparticles. The encapsulation efficacy of salicylic acid increased from 49% for pure stearic acid to 69% for samples containing 40% by weight of oleic acid, probably due to impaired crystallization of ...

2023年6月17日 · Stearic acid (SA) is an intermediate product of the HDO reaction of ricinoleic acid (RA); in this reaction RA loses a hydroxyl group, and its double bond is easily hydrogenated; thus, producing the stearic acid (SA).

2025年1月1日 · Stearic acid plays an important role not only in the constitution of lipids such as triglycerides (TGs), waxes, glycolipids, but also in maintaining membrane structural integrity and functional regulation [14].

2023年7月10日 · The stearic acid-modified NiO nanoparticles show higher water contact angle than the unmodified NiO nanoparticles suggesting their hydrophobic nature. The surface-modified NiO nanoparticles perform as better adsorbent for CV removal from solution compared to the unmodified NiO nanoparticles.

硬脂酸 （英語： Stearic acid）， IUPAC 系統名 為 十八（烷）酸 （英語： Octadecanoic acid），是一種 有机化合物 中的饱和 脂肪酸。 固態為一种难溶于水的蜡状固体，化学式C 18 H 36 O 2，可溶于 乙醇 和 丙酮，易溶于 乙醚 、 氯仿 、 四氯化碳 、 苯 和 二硫化碳 等溶剂中。 硬脂酸在自然界的分布很广，存在于许多 植物性油脂 和 動物脂肪 中。 动物脂肪中的含量比在植物油脂中的含量要高，如 牛油 中的含量可达24%， 茶油 为0.8%， 棕榈油 为6%，但 可可脂 中的含 …

This study aimed to evaluate the influence of different manufacturing parameters on the properties of stearic acid-based nanoparticles fabricated using the emulsification/solvent diffusion method. It was found that the type of organic solvent used has a major effect on the morphology of the nanoparticles, with chloroform being suitable for the ...
