摘要:
Disclosed is an eco-friendly incombustible biocomposite including: a) a polymer matrix comprising a natural fiber; and b) a ceramic sheet laminated integrally with the polymer matrix. The biocomposite is eco-friendly since the natural fiber is used as a reinforcement material and is incombustible since it is laminated integrally with the ceramic sheet. Further, it has superior storage modulus, dimensional stability and flexural properties and lightweightness, and is processable into various structures. Thus, it is very useful for automotive or building indoor/outdoor materials.

Disclosed is a cellulose electrode substituting carbon paper as a fuel cell electrode. A method of manufacturing the cellulose electrode includes cutting cellulose fibers to a predetermined length and binding the fibers, or directly weaving the fibers, thus producing a cellulose sheet, directly growing carbon nanotubes on the cellulose sheet, and supporting a platinum nano-catalyst on the surface of the carbon nanotubes using chemical vapor deposition. An electrode including the cellulose fibers and use of cellulose fibers as fuel cell electrodes is also provided. As a functional material for fuel cell electrodes, porous cellulose fibers having micropores are used, thereby reducing electrode manufacturing costs and improving electrode performance.
