Processing process for obtaining nanosheet composite material through ultrasonic rolling

Abstract

The invention discloses a processing process for obtaining a nanosheet composite material through ultrasonic rolling, and relates to the field of micro-nano manufacturing, and the processing process can be performed at the normal temperature and under normal pressure. The processing process comprises the following steps: rolling a micro-nano-scale material A by a flexible ultrasonic tool 1 with micro scale, and enabling the micro-nano-scale material A to become a sheet-shaped structure; adding a nano-scale material B onto the sheet-shaped micro-nano-scale material A, and performing re-rolling by the ultrasonic tool 1, thereby obtaining the nanosheet composite material which is co-formed by a substrate material formed by the sheet-shaped micro-nano-scale material A and a surface modifying material formed by the nano-scale material B. The processing process is performed at the normal temperature and under normal pressure, does not need any chemical reaction, and is free of requirements on ductility of the modifying material B. A rolling process in the process further can be directly performed on a base plate with an IDT electrode, and bonding between the nanosheet composite material and the base plate electrode is improved while the nanosheet composite material is processed.

Description

technical field [0001] The invention belongs to the field of micro-nano manufacturing, and in particular relates to a processing technology of nanosheet composite material by ultrasonic rolling. Background technique [0002] Driven by basic research and application prospects, people have developed a series of methods for preparing silver nanosheets, such as light-induced chemical reduction method, rapid reduction precipitation method, soft template method and sonochemical method, thermal deposition method, etc. These methods generally complete the preparation of nanosheets by means of chemical reaction or heat treatment, and the shape of the prepared nanosheets is generally triangular. The existing preparation methods of nanocomposites are divided into physical methods and chemical methods, with chemical methods being the most common. The blending method belongs to the physical method, which is to directly add nano-powder to the polymer matrix. It is a commonly used relativ...

Problems solved by technology

However, this method has certain defects. Nanoparticles are easy to agglomerate, and it is difficult to achieve uniform dispersion in the polymer during blending.

In the chemical method, based on the chemical principle, the nanocomposite material is designed, synthesized and prepared from the chemical composition, structure, properties, chemical reaction, compounding principle and its changing law of the nanocomposite material. Usually, different powder raw materials are mixed, And using conditions such as high temperature, high pressure and vacuum to prepare nanosheet composite materials, the process yield is high and suitable for large-scale production, but high temperature and high pressure conditions sometimes have a negative impact on the characteristics of some sensitive nanomaterials, so the existing nanosheet composite materials Processing technology has certain limitations
