Abstract

The invention discloses a preparation method of a flexible transparent conducting polymer thin film with antibacterial properties, and belongs to the technical field of nanocomposite materials. The preparation method comprises the steps: preparing stably dispersed graphene oxide (GO) colloid by a Hummers method at first; next, performing surface modification on the graphene oxide under the electrostatic adsorption action of poly(diallyldimethylammonium chloride) (PDDA) and preparing a nanowire/graphene nano hybrid material by a method of inducing the growth of silver nanowires in situ, and then further preparing a silver nanowire/graphene/polyvinyl alcohol thin film by a solution casting method. The thin film has the characteristics of antibiosis, high electricconductivity, high lighttransmittance, flexibility and the like, and is expected to be applied to a plurality of fields such as biosensing and nano-devices; and therefore, the flexible transparent conducting polymer thin film with antibacterial properties has a wide application prospect.

Description

technical field [0001] The invention relates to a preparation process of graphene-based nanocomposite materials, and belongs to the technical field of graphene nanocomposite materials. Background technique [0002] As a functional material with the ability to conduct electricity and eliminate static charges, conductive polymers have great development potential and application value in the fields of antistatic, electromagnetic shielding, and anticorrosion. Conductive polymers can be divided into structural type (intrinsic type) and composite type (doped type) according to composition and conductive mechanism. Composite conductive polymers have gradually become a class of conductive materials with active research, rapid development and wide application due to their obvious advantages in conductivity, stability, and processability. It conducts electricity by adding conductive fillers to the non-conductive polymer matrix. Its conductive mechanism is generally believed that the ...
