Preparation method of chopped SiC fiber surface carbon coating
The invention discloses a short-cut SiC fiber surface carbon coating preparation method, which comprises: carrying out oxygen plasma modification treatment on short-cut SiC fibers to obtain oxygen plasma modified SiC fibers, and carrying out chemical metal plating on the oxygen plasma modified SiC fibers to obtain metal-plated SiC fibers, placing the metal-plated SiC fiber in a saccharide solution for hydrothermal reaction to obtain the SiC fiber with a carbon coating on the surface; the preparation method comprises the following steps: firstly, carrying out oxygen plasma modification treatment on the surface of the SiC fiber, activating the surface of the fiber, improving the binding force between a carbon coating and the fiber, then carrying out chemical plating on the surface of the fiber, promoting the carbon coating to uniformly and rapidly grow on the surface of the fiber, and finally, adding sodium carboxymethyl cellulose into a saccharide solution to disperse the fiber so as to obtain the SiC fiber. And the growth speed of the carbon coating is accelerated through the catalyst, and finally the uniform and compact carbon coating with excellent bonding performance is obtained.
本发明公开了一种短切SiC纤维表面碳涂层的制备方法，将短切SiC纤维进行氧等离子体改性处理，获得氧等离子体改性处理的SiC纤维，然后对氧等离子体改性处理的SiC纤维进行化学镀金属，获得镀金属的SiC纤维，将镀金属的SiC纤维置于糖类溶液中进行水热反应，即得表面含碳涂层的SiC纤维；本发明的制备方法，首先对SiC纤维表面进行氧等离子体改性处理，活化纤维表面，提高碳涂层与纤维之间的结合力，然后再进行纤维表面化学镀，促进碳涂层在纤维表面均匀快速生长，最后在糖类溶液中，加入羧甲基纤维素钠使纤维分散，再通过催化剂促进加快碳涂层的生长速度，最终获得均匀、致密，结合性能优异的碳涂层。
