Abstract

The invention relates to a method for preparing a PET (polyethylene terephthalate) weaving material provided with an anti-bacterial and mineralization-promoting functional coating by adopting an atomic layer deposition method. The method comprises steps as follows: preparation of the PET weaving material: PET silk threads are woven to form latticed, tubular, rope-shaped or other compound-shaped materials; surface treatment of the PET weaving material; atomic layer deposition of zinc oxide on the PET weaving material. The prepared PET weaving material has a good anti-bacterial property and a mineralization-promoting function and can be used for repair of ligaments contacted with bones or bone tissue; the method belongs to the field of biological materials, and the prepared material can be widely applied to tissue repair and drug delivery.

Description

technical field [0001] The invention relates to a method for preparing a surface coating of a polyethylene terephthalate braided material, in particular to an atomic layer deposition method for preparing a polyethylene terephthalate braid with an antibacterial and mineralization-promoting functional coating material method. The method belongs to the field of biological materials, and the prepared materials can be widely used in tissue repair and drug carriers. Background technique [0002] PET materials are widely used in biomaterials, such as artificial blood vessels and artificial ligaments, but they are not biologically active, and there are still problems in their compatibility with tissues. For example, when used for artificial blood vessel repair, its surface does not have anticoagulant properties, which can easily lead to thrombus; when used for ligament repair, its surface cannot promote tendon-bone healing, which can easily lead to loosening. Therefore, the succes...
