AI Technical Summary
Existing conductive flexible matrix materials struggle to balance conductivity, mechanical strength, washability, structural stability, and environmental friendliness. Furthermore, bacterial cellulose is prone to uneven distribution of conductive nanofillers and damage to its crystalline structure during modification.
A metal coating was introduced onto the surface of a bacterial cellulose membrane by in-situ modification of bio-copolymerization combined with polymer-assisted metal deposition technology. The amine-modified bacterial cellulose membrane was prepared by microbial copolymerization, and a conductive coating was formed on the membrane surface by surface-initiated atom transfer radical polymerization and electroless deposition.
The prepared conductive bacterial cellulose membrane has excellent conductivity, good mechanical strength and environmental friendliness, and is suitable for smart wearable sensing devices. It achieves high efficiency in biocompatibility and biodegradability, and the preparation method is simple, low-cost and environmentally friendly.
