General description
十四烷是14个碳原子的烷烃。在合成中常充当有机溶剂。正十四烷作为非极性脂肪族溶剂，对脂肪族侧链的溶解性较好，但对芳香族的较差。
Application
十四烷可用于研究H2O/正烷烃/C12E5（五甘醇单十二烷基醚）微乳液滴的热扩散行为。
十四烷还用作：
十四烷还用作：
- 微胶囊芯材，用于制备NEPCM（纳米胶囊相变材料），其中十二烷基硫酸钠为乳化剂，间苯二酚为体系改性剂，尿素–甲醛为壁材。
- 选择性溶剂，用于研究嵌段共聚物溶体的相行为。

Underwater adhesion represents a huge technological challenge as the presence of water compromises the performance of most commercially available adhesives. Inspired by natural organisms, we have designed an adhesive based on complex coacervation, a liquid-liquid phase separation phenomenon. A complex

In this work, we report the systematic investigation of a multiresponsive complex coacervate-based underwater adhesive, obtained by combining polyelectrolyte domains and thermoresponsive poly(N-isopropylacrylamide) (PNIPAM) units. This material exhibits a transition from liquid to solid but, differently from most reactive glues

The behavior of mixed-ligand-coated gold nanoparticles at a liquid-liquid interface during compression has been investigated. The system was characterized by measuring pressure-area isotherms and by simultaneously performing in situ X-ray studies. Additionally, Monte Carlo (MC) simulations were carried out in
