Fiber-reinforced polymer composites

Solutions of celtulose (Cell) in dimethylacetamide (DMAc)/lithium chloride (LiCl) solvent are spun and annealed. The resulting fibers show various polymorphs with the different coagulants and annealing temperatures. Prior to annealing, as-spun fibers show Cell III morphology without differentiating the kind of coagulants. Fibers annealed at 170°C show Cell IV morphology and have better tensile strength than fibers annealed at 190°C, which show Cell III morphology.
