3. Composite materials and dispersion


   Electrochemical energy storage and energy conversion devices such as batteries, supercapacitors or nanogenerators are becoming more and more important in the dual context of the challenge of global warming and the depletion of fossil fuels. New materials and structures are key to progress in this field. Compared with traditional battery and supercapacitor materials, carbon nanomaterials have excellent ion transport and electronic conductivity. They can also occupy all the intercalation sites available in the particle volume, enabling high specific capacity and fast ion diffusion.These properties enable carbon nanomaterial-based electrodes to withstand high currents, providing a promising solution for high-energy and high-power energy storage.Carbon materials have the advantages of low cost, various forms (powders, fibers, aerogels, composites, layers, tubes, etc.), ease of processing, relatively inert electrochemistry, and controllable porosity and active sites.Our team is dedicated to improving the performance of energy storage and conversion through the structural design of carbon materials. In particular, we are interested in the application of energy materials under extreme conditions, such as shock-resistant energy materials and energy materials that can operate at extreme temperatures.

4. Integrated medical device for human health


         The integration of diagnosis and treatment is a new type of biomedical technology that organically combines the diagnosis and treatment of diseases. The rapid development of integrated devices for diagnosis and treatment has changed the traditional medical model. Because the integration of diagnosis and treatment integrates the functions of diagnosis and treatment, compared with There are obvious advantages over a single model.It has great potential in refined patient classification and personalized medicine, drug delivery, and implementation of drug feedback.For example, measure various health-related signs such as body movement, muscle movement, pulse, heart and breathing rate, body temperature, skin and respiratory humidity, electrophysiological signals such as electrocardiogram(ECG), electromyography(EMG), brain Electrograms (EEGs), electroophthalmograms (EOGs), and electrogastrograms (EGGs), as well as biochemical components (such as metabolites and electrolytes), and process the information to give comprehensive treatment recommendations.Compared with other candidate materials, advanced carbon nanomaterials such as carbon nanotubes (CNTs), graphene (including graphene oxide (GO) and reduced graphene oxide (rGO)) and other carbon materials (such as graphite, carbon black and Carbon materials derived from natural biomaterials) have unique advantages such as good electrical conductivity, high chemical and thermal stability, low toxicity, and easy functionalization, which make them have great application potential in integrated medical devices.

1. Structural mechanics for extreme high and low temperatures


     The C=C covalent bonds of carbon nanomaterials offer a unique combination of superior mechanical properties, electrical conductivity, thermal conductivity, and structural stability compared to conventional materials, making them ideal components for constructing macroscopic frameworks in extreme environments. Pure carbon nanomaterials are produced primarily through CVD and self-assembly technologies, which have demonstrated a variety of unique extreme environmental properties, such as mechanical damping properties over a wide temperature range, excellent specific conductivity at high temperatures, and thermal deformation resistance.  These properties benefit applications in aerospace, polar exploration and other extreme high and low temperature environments. Nanocarbon matrix composites are mainly prepared by material melting combined structure and chemical modification.  Many examples of high temperature, high pressure, corrosion and radiation resistance have been realized by combining carbon nanomodules with matrix materials, demonstrating the practical application prospect of carbon nanomaterials in complex extreme environments.  We use carbon nanomaterials such as carbon nanotubes and graphene as basic structural units to prepare macroscopic carbon nanomaterials with excellent mechanical properties, including viscoelasticity, creep, adhesion, and stretching, through rational structural design.


2. Highly Sensitive Sensing for Underwater


        In the "China Ocean Engineering Science and Technology Development Strategy 2035", China has made it clear that it is necessary to break through the bottleneck of the core technology and equipment of ocean monitoring, observation and monitoring systems, including sensor integration, marine big data applications, etc., and to develop autonomous underwater. Detecting devices and realizing underwater target detection are listed as key development directions.The detection of underwater low-frequency signals has always been a difficult problem in the field of underwater detection, and it is the "stuck neck" problem of the first echelon. The frequency of underwater activities (such as fish swimming, ocean current movement, seafloor plate movement, etc.) containing rich marine information resources is mostly concentrated in the 0.1-20 Hz frequency band. The new pressure-induced potential change detection principle is used as the support for breaking through the bottleneck. Through the precise control of the microstructure parameters of the carbon nanotube core detection functional layer and the design of the macroscopic configuration, the sensitivity of the microstructure and configuration factors to low-frequency detection and pressure detection are clarified. The mechanism of action of range and frequency response range to support the improvement of low-frequency detection performance;In addition, focusing on the stable and long-term detection requirements in the complex marine environment, the influence of environmental factors (water temperature, salinity, etc.) on the pressure-induced potential changes is systematically explored.
