    • The present invention relates to a thermosensitive phosphazene-based polymer having a degradation controllable ionic group, a use thereof, and a use thereof as a material for delivering bioactive substances. The phosphazene-based polymer according to the present invention has the thermosensitivity of showing the temperature-dependent sol-gel phase transition. Thus, it forms a gel phase at the body temperature when it is injected into the body to make it easy to control the release of bioactive substances such as drugs, and has the functional groups capable of making chemical bonds such as ionic bond, covalent bond, coordinate bond, etc. with drugs and thus is excellent in bearing the drugs. Since it can control the degradation rate depending on the kind of ionic group, it can selectively control the release time depending on the characteristics of drugs. Furthermore, it has an excellent biocompatibility and thus is very useful as a material for delivery of bioactive substances such as drugs, etc.
    • 本发明涉及具有降解可控离子基团的热敏磷腈基聚合物,其用途及其用作输送生物活性物质的材料的用途。 根据本发明的磷腈基聚合物具有显示温度依赖性溶胶 - 凝胶相变的热敏性。 因此,当其注入体内时,其在体温下形成凝胶相,以便容易地控制生物活性物质如药物的释放,并且具有能够进行化学键的官能团,例如离子键,共价键 ,配合药物等,因此具有优异的耐药性。 由于可以根据离子基团的种类控制降解速率,因此可根据药物的特性选择性地控制释放时间。 此外,它具有优异的生物相容性,因此作为用于递送生物活性物质如药物等的材料是非常有用的。

    • Provided is a nanocomposite binder for an electrode mix of a secondary battery, comprising carbon nanotubes in a photo- and/or thermo-polymerizable material or polymer, or a mixture thereof; and a lithium secondary battery comprising the same.The carbon nanotube-containing composite binder according to the present invention and a lithium secondary battery comprising the same employs a novel nanocomposite, prepared by combination of carbon nanotubes with a conventional binder material, as a binder of an anode. As a result, the present invention provides advantages such as improved conductivity of the anode due to decreased electrical resistance of the binder, and enhanced mechanical properties of the binder and thereby being capable of preventing the separation of an anode active material layer from a current collector due to volume changes occurring upon charge/discharge cycles.
    • 本发明提供一种用于二次电池的电极混合物的纳米复合粘合剂,其包含光 - 和/或热可聚合材料或聚合物中的碳纳米管或其混合物; 和包含该锂二次电池的锂二次电池。 根据本发明的含碳纳米管复合粘合剂和包含该纳米复合材料的锂二次电池使用通过碳纳米管与常规粘合剂材料组合制备的新型纳米复合材料作为阳极的粘合剂。 结果,本发明提供了优点,例如由于粘合剂的电阻降低导致阳极的导电性提高,粘合剂的机械性能的提高,从而能够防止阳极活性物质层与集电体分离 由于充放电循环时发生体积变化。
