Objective: To determine the chemical structure, tensile strength, porosity, and degradability of polyvinyl alcohol (PVA)-collagen-hydroxyapatite (HA) composite membranes for guided tissue and bone regeneration.
Materials And Methods: The PVA-collagen-HA composite membrane was divided into three groups: the group without irradiation, the group with 15 kGy irradiation, and 25 kGy irradiation. Each group was tested for chemical structure with Fourier-transform infrared (FT-IR) at a wavelength of 400 to 4,000 cm.
