Abstract

The invention relates to a graphene oxide inkjet recording material and a manufacturing method of the graphene oxide inkjet recording material, which aim at solving the technical problems that the existing expansion type ink absorption layer inkjet recording material slowly absorbs ink and the interspace type ink absorption layer inkjet recording material likely has folded flaws. The graphene oxide inkjet recording material provided by the invention is composed of a base and a graphene oxide / acrylic copolymer coated on the base. The manufacturing method provided by the invention comprises the following steps: 1, oxidating graphite; 2, purifying the graphene oxide; 3, functionalizing the graphene oxide; 4, adding double-bond graphite oxide, acrylic acid, water and initiator in a reactor to react under the protection of insert gas so as to obtain the graphene oxide / acrylic copolymer, and then coating the graphene oxide / acrylic copolymer on the base to obtain the graphene oxide inkjet recording material. The graphene oxide inkjet recording material provided by the invention can be applied to the field of inkjet printing.

Description

technical field [0001] The invention relates to a graphene composite material and a preparation method thereof. Background technique [0002] With the advancement of modern science and technology, digital technology has developed rapidly in today's world. Followed by the increasing popularity of personal computers, networks, and digital cameras and the rapid development of electronic publishing systems, hard copy output of various digital images is becoming more and more important. Due to the low price and high printing quality of inkjet printers, it has gradually become the main choice for offices and homes. Inkjet printing technology consists of three parts: inkjet printer, printing ink and inkjet printing recording medium. In the production process of inkjet recording media, ink-absorbing layer technology is its core technology, which directly determines the quality of finished products and also marks the technological progress of inkjet recording media products. The w...
