Cellutech is a company focused on innovation, development and commercializing of new sustainable materials based on wood. The innovations within Cellutech are developed in close collaboration with the scientists in the research center Wallenberg Wood Science Center (WWSC), Sweden. Cellutech offers technologies for preparation of hollow cellulose spheres, nanocellulose foams, magnetic cellulose composites, non-toxic superhydrophobic surfaces, and various polymers for cellulose fiber modification.<br/><br/>A technique for preparing hollow spheres from cellulose has been developed. The properties of the hollow cellulose spheres can be tailored and the sizes can be varied from micrometers up to millimeters, and are of particular interest for encapsulation. The shells can either be porous or solid depending on the desired application. The spheres with porous shells can release desired compounds through the shells, and gas filled spheres with solid shells can be used as filling or packing material.<br/><br/>A highly porous, lightweight solid nanocellulose material has been prepared. The solid foam has very good mechanical properties in relation to its weight and other parameters such as, stiffness and flexibility can be varied according to application The cellulose foam material has potential applications such as insulation, packaging and absorption material.
