产品介绍

多水高岭土纳米粘土具有管状形态。多水高岭土具有较低的导电率和导热率以及较强的氢相互作用，因此，其内部羟基比表面羟基更稳定。温度接近300°C会使孔隙水流失。与蒙脱石相似，多水高岭土由Al:Si比值为1:1的两层硅铝酸盐组成。据报道，在聚合物复合材料中加入多水高岭土纳米管时，可显著改善材料的热力性质和机械性能。应用多水高岭土常被用作各种纳米复合材料的增强剂，其中一些为：等规丙烯-多水高岭土纳米复合材料。通过无电/自催化沉积获得的合金复合材料。聚对苯二甲酸丁二酯(PBT)复合材料。锌-高岭土纳米管(HNT)复合涂层。埃洛石纳米管- 羟磷灰石-透明质酸膜。高岭土与聚酰胺、聚丙烯、聚（ε-己内酯）和氟弹性体结合。管状形态、高长径比和低渗透性使其成为纳米复合材料的增强剂。 Halloysite nanoclay has a tube like morphology. It shows low electrical, thermal conductivity and strong hydrogen interactions, on account of which the inner hydroxyl groups show greater stability than the surface hydroxyl groups in halloysite. The loss of hole water occurs at nearly 300 °C. Similar to montmorillonite, halloysite consists of two layers of aluminosilicate in 1:1 Al:Si ratio. Significant improvements in thermal, mechanical properties have been reported on addition of halloysite nanotubes in polymer composites. Application Halloysite is frequently used as a reinforcement in various nanocomposites, some of which are listed here: Isotactic propylene-halloysite nanocomposites. Alloy composites by electroless/ autocatalytic deposition. Poly(butylene terephthalate) (PBT) composites. Zinc–halloysite nanotube (HNT) composite coatings. Halloysite nanotube–hydroxyapatite–hyaluronic acid films. Halloysite combined with polyamide, polypropylene, poly(ε-caprolactone) and fluroelastomers. Its tube like morphology, high aspect ratio, and low percolation enables interesting applications as reinforcements in nanocomposites.
