Present Situation and Development Trend of Paper-based Friction Materials (1)
With the development of modern science and technology, the demand for paper-based friction materials is getting higher and higher. However, most functional materials have disadvantages such as high cost and complicated manufacturing process, which can no longer meet the increasing application requirements. On this basis, , paper-based friction materials have become a focus of research on cutting-edge technology.
1. Paper-based friction material
1.1 Paper-based detection chip
An important function of paper is that it is often regarded as a support material for separation and rapid detection technology. The use of paper chips can achieve resolution technology and quantitative analysis that cannot be achieved by traditional test paper, so it can make food in the sample and pollutants in the environment Fast, cheap and portable analysis, paper chip as a new important member of microfluidic chip, compared with the traditional chip, it is low cost, easy to prepare, can be cheap and effective without the help of complex peripheral equipment. Analytical tests are one of the key targets of the future diagnostic market.
Paper-based microfluidic chips use paper as a substrate to replace materials such as glass, silicon, and polymers. This kind of analytical detection device is called a microfluidic paper analysis device. Ideal hydrophobic blocks can be designed on paper through wax spray printing, laser segmentation, printing, drawing, inkjet technology, etc., so that the fluid to be analyzed can flow according to the designed hydrophilic channel, and various biochemical analyzes can be realized.
1.2 Paper-based carrier ceramics
Using ordinary paper as raw material, the paper is processed by gel-sol technology, and the ceramic carrier composite material formed by various chemical reactions through folding, pasting and other bionic designs can improve the single performance of ordinary materials, such as improving strength, improving Resilience and so on. It is widely used in aerospace, military and other departments. The carrier ceramics made of high-strength and high-elastic paper can greatly improve its toughness and reliability.
1.3 Paper-based flexible electronic circuits
The development of contemporary electronic products is moving in the direction of light weight and flexibility. It is difficult for rigid circuit boards in the traditional sense to meet the needs of current electronic devices. The paper-based circuit is light in weight, biodegradable, and the formed circuit is easy to fold, which is of great significance to the development of flexible printed electronics. Using ultrasonic vibration technology to make uniformly distributed nano-silver conductive ink, put the well-made conductive ink into the refill of the signature pen, and then make conductive lines on the paper substrate to produce a paper-based flexible circuit.
