Abstract

The invention discloses a preparation method and application of an intelligent fabric used for information storage and hydrogen fluoride visual detection. The preparation method is as follows: the fabric is pretreated, the azophenylmaleimide polymer is made into a polymer solution, and a layer of polymer is spun on the surface of the pretreated fabric by electrospinning, and the fabric is taken out. Get the orange smart fabric after it's down. The application of the smart fabric of the present invention in information storage is as follows: when the smart fabric is placed in an acidic environment, the smart fabric changes from orange to orange-red; when the discolored smart fabric is placed in an alkaline environment, the smart fabric changes from orange-red to orange-red. orange. The fabric prepared by the invention is reversible in color development under acid stimulation and recovery under alkali stimulation, realizing the reversible cycle of patterning; it can also be used for visual detection of hydrogen fluoride gas, which has important fundamental significance for the development of fluorine chemical industry.

Description

technical field [0001] The invention relates to the technical field of reversible response materials, in particular to a preparation method and application of a smart fabric used for information storage and visual detection of hydrogen fluoride. Background technique [0002] In recent years, reversibly responsive materials (RRMs) have played an important role in rewritable media, encryption, sensors, secure printing, etc., which can reveal the effects of external stimuli on vision. Rewritable media in the information sector, in particular, offer new possibilities for reducing the burden of paper consumption when billions of tons of paper are consumed every year poses dangerous environmental and sustainability concerns. However, due to the complexity of preparation and high cost, its development is limited in practical production. [0003] Recently, textile products have been widely used in oil-water separation, biomedicine, electronic devices, sensors, and artificial intell...
