BaWO_(4) nanoparticles of wire,rod,and hollow spherical shapes were prepared in different microemulsion systems with octane as the oil,and undecylenic acid and/or dodecylamine as the surfactants.
在十一烯酸和十二胺作表面活性剂、正辛烷为油形成的油包水(W/O)型微乳液体系中,通过调节体系的组成,使Na2WO4和BaC l2发生反应,分别制得了丝状、棒状和空心球状的BaWO4纳米粒子。
A three-unite hydrogel that had a thermoresponsive shape memory was prepared by copolymerizing a hydrophobic monomer n-stearyl acrylate(SA) with n-undecylenic acid(HA) and acrylamide(AM),and its structure and properties were studied by X-ray diffraction,DSC and DMA.
选用疏水性单体丙烯酸十八酯(SA)和十一烯酸(HA)以及亲水性单体丙烯酰胺(AM)制备了三元共聚凝胶P(SA-co-AM-co-HA),通过X射线衍射、DSC、DMA等对三元凝胶的结构和性能进行了研究,发现三元凝胶形成了有序排列,这种有序排列会随着温度的变化发生可逆转变,从而使凝胶显示较好的形状记忆特性。
