摘要：

高分子纳米颗粒在生物、医药和催化等领域具有良好的应用前景. 聚合诱导自组装能够高效制备不同形貌的纳米颗粒. 离子液体具有许多独特的性质, 在许多领域具有广泛的应用. 利用离子液体[MTMA][TFSA]作为可逆加成-断裂链转移(reversible addition-fragmentation chain transfer, RAFT)分散聚合的单体, 以PDMAEMA$_{46}$作为大分子链转移剂, 在乙醇溶液中进行聚合诱导自组装, 制备出二嵌段共聚物纳米颗粒. 随着第二嵌段的聚合度增加, 颗粒的尺寸基本呈增大的趋势.

关键词: 离子液体, RAFT分散聚合, 聚合诱导自组装

Abstract:

Polymer nanoparticles have applications in biology, pharmacy, catalyst, etc. Polymerization-induced self-assembly is highly efficient for the synjournal of nanoparticles with different morphologies. Since ionic liquids have many unique properties, they have found wide applications such as catalysis, nanotechnology and biotechnology. Ionic liquid [MTMA] [TFSA] as a monomer is used for reversible addition-fragmentation chain transfer (RAFT) dispersion polymerization in ethanol, and PDMAEMA$_{46 }$ as a macromolecular chain transfer agent to self-assembly to prepare diblock copolymer nanoparticles. As the degree of polymerization of the second block increases, the size of particles tends to increase substantially.

Key words: ionic liquid, reversible addition-fragmentation chain transfer (RAFT), polymerization-induced self-assembly (PISA)
