█　项目内容

1.Background

In modern life, electronic devices based on dielectric materials are crucial and ubiquitous. The proportion of dielectric components in various electronic equipment exceeds 40%. To further improve the performance and portability of high-end electronic devices towards flexible devices, the flexibility, miniaturization and high integration of electronic materials are an inevitable trend, and a direct challenge is how to develop a class of flexible ultra-thin dielectric materials. At the same time, their dielectric properties are not sacrificed. Existing high-dielectric materials are generally based on crystal structures, and the mainstream is inorganic dielectrics such as barium titanate, with a dielectric constant of up to 1,000. However, there are two major problems with such materials: First, limited by microfabrication technology, it is very difficult to miniaturize and thin crystalline dielectric materials and cannot meet the needs of practical applications. Second, crystalline dielectrics do not have the flexibility and cannot be used in flexible electronic devices.

2.Our Only-One Technology

In this project, it is demonstrated that we have developed a novel category of liquid matters that exhibits giant-dielectric propertiescomparable to solid or crystal materials, we are going to sell them in targeting to replacing the solid devices toward REAL future flexible electronics. Our story starts from 2017, one of our members, Hiroya Nishikawa, in Kyushu university accidentally discovered that the first liquid crystal phase in the liquid crystal phase has ferroelectricity and exhibits ultra-high dielectric properties (dielectric constant>10000@1kHz, so the capacitance of a thin film exceeds 100 μF. Champion data in the world.) organic small molecules. The common sense that liquid materials cannot achieve high dielectric properties has opened up a new field in the development of liquid ultra-high dielectric materials for flexible electronics and has also inspired a bunch of subsequent studies for ours. Already, we are the only-one to have a general strategy to guide the design of high dielectric constant liquid materials that can be directly used for flexible electronics. 

Our recent effort have clarified the formation mechanism and structural mechanism of such ferroelectric ultra-high dielectric liquid materials, and used machine learning, theoretical calculations, and experimental syntheses to establish its general design strategy. All the results strongly support us to realize the application and development of flexible high-end optoelectronic components based on liquid high-dielectric materials. 

3.As a Market Changer

To step-by-step realize the future SF-technology of All-Flexible-Electronics to better people’s life, as the first strike, we target on alternating the existing solid capacitors in the current market to our liquid-based capacitor in the next ten years. The market size exceeds about 20 billion dollars in the world. We raise a simple slogan of 3M: sell the raw Material, sell flexible electronic Module, Maximize the fluid-based flexible electronic market. We are going to cover the high-end products like cuttable flexible electric circuits for facile magic use of the high-quality electronic modules in our daily life.
