Abstract
A method is provided for fabricating a shaped article from aqueous collagen-containing materials. A dispersion containing collagen and a surfactant is cast upon a mold of thermoplastic material and dried by a ramped drying profile under controlled conditions of relative humidity and temperature. The controlled drying allows for initial renaturation of the collagen dispersion then drying at high humidity to form a product with minimal residual stress.
