Description
Technical Field
The invention belongs to the technical field of printing, and particularly relates to an electrostatic jet flexible transfer printing method.
Background
Flexo transfer printing refers to the process of transferring a pattern on a substrate to a flexible substrate using a flexible stamp. The flexible transfer printing technology has wide application in the preparation of modern personalized and intelligent composite materials. Currently, stamp materials used by people include polydimethylsiloxane, flexible tapes and the like, and flexible printing materials include paper, fabric, PET and the like. Traditional transfer printing technology is usually based on flexible printing stock materials with established structures, and design and regulation of the printing stock structures are difficult to realize.
With the rapid development of novel materials such as nanofiber membranes and the like, the preparation of porous micro/nano membrane materials by adopting the electrostatic jet principle becomes one of research hotspots. In the process of electrostatic jet, a high-voltage electrostatic field is established between a high-molecular polymer liquid spray head and a receiver, and when the intensity of the electric field exceeds a critical value, polymer liquid or melt flowing out of the spray head overcomes the surface tension of the polymer liquid or the melt under the action of the electric field force to form a charged jet stream. Under the action of electrostatic repulsion, the charged jet current can bend or whip at a high speed and finally fall on a receiver to form a flexible porous micro/nano fiber film or a particle cluster with high specific surface area along with the volatilization of the solvent or the cooling of the melt. According to the difference of the product morphology formed by the jet flow on the receiver, the electrostatic jet flow can be divided into two forms of electrostatic spraying (electro spraying for short) and electrostatic spinning (electro spinning for short). The electric spraying or electric spinning can conveniently realize the low-cost and highly controllable preparation of the flexible membrane material through the cooperative regulation and parameter design in multiple aspects such as the process parameters of polymer liquid and electrostatic jet equipment, environmental control and the like. In some practical applications or due to the requirement of device assembly, the film material needs to be patterned. At present, the homogeneous patterning of the electrospun fiber membrane is studied more, and is usually prepared by methods such as chemical etching, photoresist or designing a special receiver. There is currently less research on heterogeneous patterning of electrospun fibers. For example, Beijing nanoenergy and systems institute Li, China' S institute of sciences, combines screen printing from the task group of researchers and xu Wei Hua researchers to make arrayed nanofiber air-permeable pressure sensors (Yang W, Li N, ZHao S, et al. Advanced Materials technologies, 2017, 3). Hu et al, by photolithography equipment, produced electrospun nanofiber mats into patterned printing plates having hydrophilic and hydrophobic regions through which aqueous inks can selectively pass, thereby building pH and glucose sensors on ultra-thin electrospun nanofiber mats (Hu H, Buddingh J, Wang Z, et al, Journal of Materials Chemistry C2018, 6: 808-. In addition, Yuan et al use ink-jet printing to directly print water on electrospun fibers, enabling flexible design and print preparation of color patterns, various letters, and quick response codes (Yuan S, Meng W, Du A, et al. Chinese Journal of Polymer science, 2019, 37: 729-.
These heterogeneous patterning methods described above are of great interest for the development of electrospun fiber-based functional composites and devices. However, the electrospinning technique combined with the above-mentioned patterning method requires additional equipment, the photolithography process is complicated, the equipment cost is extremely high, and the screen printing requires a special template. Therefore, the traditional flexible transfer printing technology has the defects of fixed structure of a printing stock and limited material selection. The realization of low-cost heterogeneous patterning design of flexible thin film materials is a challenge, and has important research significance and application value.
