温敏型聚酰胺-胺型树状聚合物的研究进展

温敏聚酰胺-胺型(PAMAM)树状聚合物是同时具有温敏特性和树状大分子性能的一类聚合物,其不但受温度变化会发生刺激响应,同时具有PAMAM树状聚合物多反应位点、低粘度、高支化度、特殊的三维结构等特点。这类聚合物在医用材料、纺织面料、温敏传感器等领域有着广泛的应用前景。温敏聚PAMAM树状聚合物的制备方法丰富多样,可以采用调节树状聚合物末端基元取代度、或者调节聚合物中亲水链段的比例、或在树状大分子末端接枝具有温敏性的物质等方法。本文就温敏型PAMAM树状聚合物的制备方法、温敏机理及应用领域等方面进行综述。

Research progress of temperature-sensitivepoly(amidoamine)dendrimers

The temperature-sensitive poly(amidoamine)dendrimers are smart polymers that have both the properties of temperature sensitivity and dendrimers.It possesses not only the characteristics of temperature stimulus-response,but also with multiple reaction sites,low viscosity,high branching degree,special 3D structure,etc.So,it plays an important role in smart materials,and shows a wide application prospect in biomedical materials,smart textiles,temperature sensor,and so on.The temperature-sensitive poly(amidoamine)dendrimers can be prepared by adjusting the degree of substitution into the terminal groups of dendrimers,or adjusting the proportion of hydrophilic and hydrophobic groups in the backbone of the dendrimers,or introducing temperature-sensitive polymers into the terminal of dendrimers.In this paper,the preparation of temperature-sensitive poly(amidoamine)dendrimers,and their temperature-sensitive mechanisms and potential applications were reviewed.
