一般說明

聚丙二醇是丙二醇和水的加成聚合物。它由化学式HO(C3H6O)nC3H6OH进行表示，其中n代表氧丙烯基团的平均数。聚丙二醇可溶于水和某些有机溶剂中（例如脂族酮和醇），不溶于醚和大多数脂族烃。

應用

聚丙二醇（PPG）被广泛用作消泡剂。例如，它可以用来控制苏云金芽孢杆菌基生物农药生产（从污水污泥中分离）中的泡沫。

它可以用于制备聚氨酯（PU）弹性体。例如，它可以用于合成具有良好吸声性能的 PU 弹性体。

PPG-2000 可作为柔性链段用于制备PU 基自修复聚合物网络。这些网络在软电子领域得到了应用。

特點和優勢

  • 长而灵活的烷基促进链的迁移，这有利于快速自愈。
  • 存在于聚合物两侧的甲基改善了水中的乳化性。

In this work, we proposed a novel aqueous biphasic system (ABS) composed of polypropylene glycol P400 (PPG P400) and hydrophilic ionic liquids (IL), 1-alkyl-3-methylimidazolium bromide (alkyl = ethyl or butyl), forming an upper polymer-rich phase and a lower IL-rich phase

Current treatments for cerebral aneurysms are far from ideal. Platinum coils are prone to compaction, and currently used liquid embolics are delivered with angiotoxic agents. This work presents initial in vivo studies of a novel liquid-to-solid gelling polymer system (PPODA-QT)

The controlled atom transfer radical polymerization of an ionic liquid, 1-(11-acryloylundecyl)-3-methyl imidazolium bromide (ILBr), from both ends of a telechelic poly(propylene oxide) (PPO) macroinitiator, end-functionalized with bromoisobutyryloyl is reported. The resulting highly water-soluble triblock, poly(ILBr-b-PO-b-ILBr) is multistimuli responsive. This new

A Review of Mesoporous TiO2 Thin Films

In this paper, we discuss recent advances in the preparation of various TiO2 porous structures via hard and soft-templating routes. Specifically, we focus on recent developments in TiO2 mesoporous thin films in a combined sol-gel and evaporation-induced self-assembly (EISA) process.
