Abstract
Ultrathin SiCN fibers are produced from inexpensive carbosilazane-polyethylene block copolymers. The two-step synthesis consists of a concerted block copolymer formation, microphase separation and crosslinking step, followed by pyrolysis. The fibers have a mean diameter of 45 nm and an aspect ratio of up to 100.
