Abstract

The invention discloses a method for preparing porous oil absorbing fibers with fluorescent response. The method is characterized by comprising the following steps of: 1) preparing a polymer with aggregation induced emission (AIE) effect; 2) dissolving the obtained polymer with the AIE effect into an organic solvent to form 15 to 35 weight percent spinning solution; and 3) preparing the porous oil absorbing fibers from the spinning solution by adopting the electrostatic spinning process. By adopting the method, the porous oil absorbing fibers with high luminous efficiency can be obtained; and the porous oil absorbing fibers have a good oil absorbing effect, and the fluorescent strength after the porous oil absorbing fibers absorb oil is remarkably reduced, namely the porous oil absorbing fibers have good fluorescent response.

Description

technical field [0001] The invention relates to a method for preparing a porous oil-absorbing fiber with fluorescent response. Background technique [0002] With the development of industry and the improvement of people's living standards, the discharge of oil pollution is increasing, which poses a serious threat to rivers, oceans and human living environment. 30% of the oil that pollutes the environment comes from industrial emissions, and 50% comes from the leakage of oil tankers. Facing the increasingly deteriorating environment, the development of effective oil pollution treatment methods and high-quality oil-absorbing materials has become a major research topic. [0003] Among many oil pollution treatment methods, the adsorption method based on oil-absorbing materials is widely used because of its high efficiency, economy, and ease of popularization and use. At present, a variety of oil-absorbing materials have been developed, such as inorganic silica, organic wood pu...
