The immense scope of variation in dendritic molecules (hyper-branching, nano-sized, hydrophobicity/hydrophilicity, rigidity/flexibility balance, etc.) and their versatile functionalization, with the possibility of multivalent binding, permit the design of highly improved, novel materials. Dendritic-based materials are therefore viable alternatives to conventional polymers. The overall aim of this work is to show the advantages of dendronization processes by presenting the synthesis and characterization of three different dendronized systems: (I) microbeads of functionalized chitosan; (II) nanostructuration of polypropylene surfaces; and (III) smart dendritic nanogels. The particular properties yielded by these systems could only be achieved thanks to the dendronization process.
树枝状分子具有巨大的变化范围（超支化、纳米尺寸、疏水性/亲水性、刚性/柔韧性平衡等）及其多功能化，具备多价结合的可能性，这使得设计出高度改进的新型材料成为可能。因此，基于树枝状分子的材料是传统聚合物的可行替代品。这项工作的总体目标是通过展示三种不同树枝状化体系的合成与表征来展现树枝状化过程的优势：（I）功能化壳聚糖微珠；（II）聚丙烯表面的纳米结构化；以及（III）智能树枝状纳米凝胶。这些体系所产生的特殊性能只有通过树枝状化过程才能实现。
