Expandable cellulose-based capsules

Treesearch research themes:

Project partners:



The development of expandable capsules holds a great promise for various advanced engineering applications. Preparation of such materials using renewable and sustainable resources is particularly attractive, where the development is driven by an increased global interest in new generations of green products that can meet the demands of the modern society. The aim of this project is to create a fundamental understanding of the formation of cellulose-based capsules that can significantly expand when they are exposed to an external stimulus, for example, an increased temperature or a deceased external pressure. In this work, we explore a potential for using a modified structure of cellulose that on the molecular level increases the flexibility of the capsule shell, as well as we search for alternative ways of forming gas- and liquid- filled capsules.
