Abstract
A method for making a phosphorated polymer is also provided. An organic polymer and phosphorus are mixed to obtain a mixture. A weight ratio of the organic polymer to the phosphorus ranges from about 1:10 to about 4:1. The mixture is dried in an inert atmosphere or vacuum. The mixture is heated in an inert atmosphere or vacuum so that the phosphorus sublimes and reacts with the organic polymer to form a preform. The preform is cooled down to room temperature and immersed in an alkaline solution. The pH of the preform is adjusted to be neutral. The preform is dried.
