Changes in Selected Properties of Carboxymethyl Cellulose Materials after Lyophilization

Co-authors WIENER Jakub

This study deals with the change of selected properties of samples of modified carboxymethyl cellulose after freeze drying. The investigated properties were changes in thickness, permeability, water sorption, thermal area resistance and thermal absorbing capacity. It will also be monitored thermal insulation properties under the simulated outdoor conditions. The prepared materials were evaluated by scanning electron microscopy and computed tomography. The product of presented technology has large internal surface, high wettability and biodegradability. It is nontoxic with high potential in biological aplications.
