In this work, composite Eudragit L100/phosphatidyl choline microparticles were fabricated through electrospraying. pH-responsive liposomes were found to self-assemble from these when the microparticles were added into aqueous media. The microparticles and the liposomes were both approximately spherical in shape according to electron microscopy, but the liposomes have much smaller diameters (200–300nm)...
Four kinds of room temperature ionic liquids (RTILs), as a new kind of lubricant for micro/nano-electromechanical system, with the same imidazolium cation but carrying different anions including hexafluorophosphate, tetrafluoroborate, nitrate and perchlorate were synthesized and these nano-scale films were prepared on single-crystal silicon wafer by dip-coating method. Atomic force microscopy was...
Self-assembled dual-layer films have been expected to be excellent lubricants for micro/nano-electromechanical system (MEMS/NEMS). In this research, a novel self-assembled dual-layer film was prepared on single-crystal silicon surface by chemisorption of perfluorododecanoic acid (PFDA) molecules on 3-aminopropyltriethoxysilane (APS) self-assembled monolayer (SAM) with terminal amino group. The chemical...
