A comparison of the drying processes used to prepare bacterial cellulose for wound dressing applications

Abstract

Bacterial cellulose (BC) is a promising polymer because of its ability to manage wound exudation and create a moist environment for healing. The natural form of the BC hydrogel prevents it from maintaining its shape; therefore, water needs to be removed. However, the drying conditions and processing steps can affect the physical characteristics of BC films. This article investigated the effects of drying methods on BC films, revealing structural changes in the membrane. Four different methods are selected, along with methodical research on how drying affects physiological, morphological, and structural properties. As a result, the cold-drying procedure is appropriate for the preparation of BC films for use as wound dressings.
