Functionalization and intelligentialization are the trends of the fiber development. The single component fiber is hard for performace optimization. The multi-component fiber could combine the characteristic of different components, and realize the properties integration and optimization. Different polymers aggregate together based on non-covalent bonds to form homogenous phase, which is defined as polymer complex. Polymer complex can be classified into several categories according to their characteristic rmolecular interaction, including polyelectrolyte complex, stereocomplex, hydrogen-bonded complex, inclusion complex, polymer-metal complex and charge-transfer complex. Polymer complex fibers are defined as those prepared through polymer complexation process or by directly spinning polymer complex. In polymer complex fibers, different polymers have miscibility on the molecular level, which provides a platform to design the functionality and to futher explore intelligentialization. Polymer complex fibers could be retrospected to stereocomplex fibers in early 1990s, but the mainly investigated ones were polyelectrolyte complex fibers (polyion complex fibers). Recently, hydrogen-bonded polymer complex fibers have been reported. Wan et al. made a review on polyelectrolyte complex fibers. But up to now, there is no unified concept for polymer complex fiber. This review collects research works on fibers of different types of compexes, and puts forward to the concept of polymer complex fibers. Different approaches that adopted to fabricate polymer complex fibers, like interfacial drawing, coaxial spinning, and electrospinning, are discussed. The review summarizes the properties of polymer complex fibers, such as conductivity, fluorescence, and elasticity, and focuses on their apllications in separation, controlled release, tissue engineering, anti-bacterials and catalysis. Using newly synthetized polymers or modified polymers to fabricate polymer complex fibers with multi-functionality and developing new methods and technologies to improve the efficiency of fiber fabrication are our effort directions of polymer complex fiber research.
