Embodiment 1

[0023] Example 1: Weigh 6g of polyvinyl alcohol with a degree of alcoholysis of 87-89 mol%, add it to 100ml of deionized water at room temperature and stir to make it fully swell, then slowly heat to 100 o After C, keep constant temperature, stir and disperse, fully dissolve until the solution is uniform and clear as a whole, then adjust the pH value to 3.5 after natural cooling to room temperature, and fully stir to obtain a polyvinyl alcohol solution. Add 0.5wt% carbon nanofibers to the prepared polyvinyl alcohol solution, stir mechanically to make them uniformly dispersed, then add 2.5vol% glutaraldehyde and mechanically stir for 20 min to obtain carbon nanofiber / polyvinyl alcohol excitation-response composites The pre-polymerization solution is poured into the mold and left to stand for a period of time, followed by vacuum freeze-drying treatment to obtain the carbon nanofiber / polyvinyl alcohol excitation-response composite material, figure 1 Shown are its macroscopic morp...

Abstract

The invention belongs to the field of intelligent materials and structures, and relates to intelligent manufacturing and regulation of an adsorption / release intelligent system. The structure and function of the intelligent system are high in designability, the requirement for raw materials is low, and the specific performance and structure of the intelligent system can be designed and regulated according to requirements. The technical problem that a traditional adsorption material cannot achieve controllable positioning and timed adsorption can be solved. The intelligent adsorption / release system is composed of excitation response aerogel and an excitation response expandable structure. The excitation response aerogel has the advantages of rapid target object adsorption, controllable excitation response, easy modification and compounding, good microstructure designability, easy functionality expansion and the like. The excitation response expandable structure can respond to external excitation to release the coated excitation response aerogel in a controllable expansion manner at a preset position and a preset time point in a preset manner. The intelligent system can gradually carry out unfolding, adsorbing, releasing and recyclying according to a preset mode and time, personalized customization tasks are completed, and the intelligent system has a good application prospect.
