Polysaccharides including cellulose are the most abundant sustainable materials on earth. Rather than monosaccharides, polysaccharides and their crystallized supermolecular structures provide readily applicable platforms for functional materials. For this purpose, chemical modifications demonstrate great tools for the functionalization, which leads to specific materials requiring particular further material formation.<br/>Herein, novel functional materials derived from cellulose and nanocellulose with smart and stimuli-responsive properties will be presented. These materials could be further transformed into diverse shapes ranging from particles to membranes. Different than monosaccharides, the chemical modifications for the introduction of stimuli-responsive functional groups along polysaccharide backbone are generally limited, so that the choice of appropriate modification strategy maintaining the polymeric nature and crystalline structure of nanocellulose is critical. Otherwise, the contents, distribution of these functional groups in particular within the polymeric backbones of polysaccharides and the surface density of functional groups on the nanocellulose are the major parameters affecting the performance of materials.<br/>
