二硫代磷酸硫化氧钼与硫,磷添加剂的复配特性研究

研究了二烷基二硫代磷酸硫化氧钼（ＭｏＤＴＰ）摩擦改进剂及其与硫、磷、硫－磷型添加剂复合的抗磨减摩性能。试验表明，经过适当复配后，这类合活性元素的添加剂对ＭｏＤＴＰ的抗磨减摩性能均有增效作用，同一类型添加剂的活性愈高，增效作用愈显著。同时利用扫描电镜和Ｘ－射线能谱仪进行摩擦副表面膜的形貌照相及元素分析，对复合作用的机理进行了初步探讨。

Nanoscale Hybrid Langmuir－Blodgett Films Based on Cerium－Substituted Heteropolymolybdate and Polyquinoline

Nanoscale hybrid organic/inorganic Langmuir-Blodgett films of cerium-substituted heteropolymolybdates (CeHPMo) and π-conjugated macromolecule poly(1,2-dihydro-2,2,4-trimethyl) quinoline (PQ) were obtained with auxiliary film-forming material stearic acid(SA) or octadecylamine(ODA). The surface pressure-area isotherms illuminate the formation of the hybrid LB films of PQ/ODA/Ce-HPMo and PQ/SA/Ce-HPMo. The different film-forming mechanism was discussed when the different auxiliary film-forming materials were used in the system. The absorption spectra indicate that the molecules of PQ and Ce-HPMo are incorporated into the LB films. Tapping-mode AFM image reveals a granular surface texture of nanosized Ce-substituted heteropolymolybdate. STM image shows that the conductivity is greatly improved after Ce-substituted heteropolymolybdates are incorporated in the films.
