Positive energy battery, pressure sensor, electronic skin and wearable electronic sensor etc..Traditional method, it is mostly conductive using metal/semiconductor
The elastomer of nano material (such as carbon nanotube, silver nanowires, graphene oxide) coated high transparency, but this method may
Soft or hard material interface is caused to fail, so as to cause transparency decline.Ionic gel elastomer has the tensility of inherence because of it,
And electric conductivity and high transparency, the traditional ionic gel of more and more concern is caused usually by high-cost or need
The group of complicated post-processing is wanted to be grouped as, the application after polymerizeing which has limited them as functional material.Low brilliant solvent altogether
Appear in the beginning of this century as a new class of ionic liquid, and it many advantages, Ru at low cost, (constituent be can be
Biomass or derivative from fossil deposit), (by very economical route and process is simply mixed) in manufacturing process green,
Biodegradable, good biocompatibility, nontoxicity etc..However, component generally passes through weak hydrogen bond company in low brilliant solvent altogether
It connects, so that its mechanical performance is poor, especially, after absorbing water in air, mechanical performance is further decreased.
Bacteria cellulose be a kind of molecular formula is β-Isosorbide-5-Nitrae-glycosidic bond polysaccharide as plant cellulose, but and papermaking
Plant cellulose used is compared, and has several clear advantages.From the perspective of ingredient, bacteria cellulose is pure cellulose
