Abstract

The invention discloses a large-deformation quick-response intelligent driver for monitoring organic gases, which is a graphene oxide / cellulose acetate composite film with a width-to-length ratio of 3 mm: 3-5 cm and a thickness of 80-150 μm. The preparation method is carried out sequentially according to the following steps: prepare a neutral graphene oxide suspension with a mass fraction of 0.05-0.2%; take the neutral graphene oxide suspension and place it in a vacuum filtration device, and use a filter with a pore size of 0.22-0.65 μm Cellulose acetate was used as the filter membrane, and after vacuum filtration, the graphene oxide / cellulose acetate composite blank film was obtained; the graphene oxide / cellulose acetate composite blank membrane was dried at room temperature for 12 hours to obtain graphene oxide with a thickness of 80-150 μm / Cellulose acetate composite film, cut into strips with a width-to-length ratio of 3mm: 3~5cm.

Description

technical field [0001] The invention relates to the field of intelligent materials, in particular to a large-deformation quick-response intelligent driver for monitoring organic gases and a preparation method. Background technique [0002] Smart drive is a kind of intelligent attribute material that integrates perception, drive and information processing to form bionic materials, and has functions such as self-sensing, self-diagnosis, self-adaptation, and self-repair. According to the different external stimuli (driving force), intelligent drives can be divided into electric drive, light drive, thermal drive, gas drive, etc. At present, the organic gas smart actuators reported in the literature are as follows: Porous polymers with different pore size gradients prepared by Zhao et al. (Nat. Commun. 2014, 5(5):4293); Chen et al. using helical assembly of carbon nanotubes Preparation of helical actuation fibers (Nature Nanotech.2015,10(12):1077); Zhang et al. prepared a polyme...
