Preparation method of black bioactive ceramic dressing
The invention provides a preparation method of black bioactive ceramic dressing. The preparation method comprises the following steps: preparing an antibacterial layer; dissolving PVA in water, adding MXene, stirring, filtering to obtain first composite gel, and performing vacuum drying on the first composite gel to obtain a micro-current layer; adding magnesium powder into the white bioactive ceramic powder to be mixed, then placing the mixture in a furnace and calcining under protective gas, and obtaining black bioactive ceramic powder; dissolving black bioactive ceramic powder in a carbomer solution, uniformly stirring and filtering to obtain second composite gel, and performing vacuum drying to obtain a black bioactive ceramic layer; inoculating acetobacter xylinum into a culture medium for culture, cleaning after culture is finished, soaking in an alkaline solution, cleaning again after soaking is finished, and sterilizing and slitting to obtain a bacterial cellulose membrane; preparing a backing layer; preparing a finished product. An infection-free environment is provided for wound healing; inflammatory response is reduced, revascularization is promoted, and the wound epithelization process is accelerated; the wound healing is accelerated.
一种黑色生物活性陶瓷敷料的制备方法，步骤：制备抗菌层；将PVA溶解于水中，加入MXene搅拌，过滤，得到第一复合凝胶，将第一复合凝胶真空干燥，得到微电流层；将镁粉加入到白色生物活性陶瓷粉末中混合，再置于炉内且在保护气体下煅烧，得到黑色生物活性陶瓷粉末；将黑色生物活性陶瓷粉末溶解于卡波姆溶液中，搅匀过滤，得到第二复合凝胶并真空干燥，得到黑色生物活性陶瓷层；将木醋杆菌接入培养基中培养，培养结束后清洗，而后在碱溶液中浸泡，浸泡结束后再次清洗，然后灭菌处理，分切，得到细菌纤维素膜；制备背衬层；制备成品。为伤口愈合提供无感染环境；降低炎症反应、促进血管再生、加快伤口上皮化过程；加速伤口愈合。
