Abstract
A flat self-curling rollable composite sheet membrane, and methods for preparing such membranes. The sheet membrane includes a flat layer of collagen and a bioactive agent, such as a calcium phosphate-based mineral. The flat layer self-curls into a predetermined shape upon absorption of an aqueous fluid. The methods for preparing the membranes include the steps of adding mineral to a collagen dispersion, forming a composite collagen matrix having mineral particles dispersed therein, compressing the composite matrix between two plates to form a flat sheet, and drying the flat sheet to yield a rollable composite sheet membrane.
