这份报纸报导在结构上断然控告了分层的双氢氧化物(LDH ) nanoparticles 在两性离子的表面活化剂, lauryl sulfonate betaine (LSB ) ,和 anionic 表面活化剂的混合物导致泡形成,钠 dodecyl benzenesulfonate (SDBS ) 。泡的存在被表明由否定染色(NS-TEM ) 并且结冰破裂(FF-TEM ) 传播电子显微镜学和共焦的激光扫描显微镜学(CLSM ) 。泡的尺寸随 Mg3Al-LDHs 大音阶的第五音的体积比率(Q) 的增加增加了到 SDBS/LSB 答案。一新在泡包含的 LDH nanoparticles 合成被形成。导致 LDHs 的泡形成的可能的机制被建议。否定地吸引的正电荷 LDH 表面控告了微粒或免费 amphiphilic 分子,它便于他们的聚集进 bilayer 膜。bilayer 膜能接近把 LDH 粒子包含的形式泡。LDH 表面上的 LSB 和 SDBS 微粒或分子的吸附的复合的层在泡形成起了一个关键作用,这也被发现。
This paper reports that structurally positively charged layered double hydroxides (LDHs) nanoparticles induce the vesicle formation in a mixture of a zwitterionic surfactant, lauryl sulfonate betaine (LSB), and an anionic surfactant, sodium dodecyl benzenesulfonate (SDBS). The existence of vesicles was demonstrated by negative-staining (NS-TEM) and freeze-fracture (FF-TEM) transmission electron microscopy and confocai laser scanning microscopy (CLSM). The size of vesicles increased with the increase of volume ratio (Q) of Mg3A1-LDHs sol to the SDBS/LSB solution. A new composite of LDHs nanoparticles encapsulated in vesicles was formed. A possible mechanism of LDHs-induced vesicle formation was suggested. The positive charged LDHs surface attracted negatively charged micelles or free amphiphilic molecules, which facilitated their aggregation into a bilayer membrane. The bilayer membranes could be closed to form vesicles that have LDHs particles encapsulated. It was also found that an adsorbed compound layer of LSB and SDBS micelles or molecules on the LDHs surface played a key role in the vesicle formation.
