The aim of this paper is to study the properties of collagen, which is used as a promoting bioelectret for wound healing. So first of all, a bioelectret material based on collagen was prepared, then the processes of thermally stimulated discharge of collagen were measured under different conditions. Cell culture studies were used in the determination of the suitability of this kind of bioelectret as surfaces for the attachment and growth of cells. Some results show the potential use of bioelectret collagen in soft tissue wound healing.
