In this invention, the fluorinated graphene(FG) is obtained by the fluorination of electrochemically exfoliated graphene (ECG), which is found to be a one-step approach for the scalable preparation of FG. The precursor with fluorine atoms is mixed with the ECG followed by applying lower energy to produce the fluorinated graphene. This process demonstrates an eco-friend and safe as well as scalable features. We have demonstrated their multi-functional applications on surface coatings, including the outperformance anticorrosion passivation, hydrophobic surface with ultra-strong adhesion, and high safety energy storage device. This technology provided a new strategy for next-generation functional and atomic layered coatings.

Current 5G communication devices have a huge demand in high resolutiondensity of metal conducting wires in electronics ( 40 μm line width/line spacing), which cannot be achieved by conventional screen printing (100 μm). Our group cooperated with Ample Technology to develop a new-generation silver conductive paste which enables photolithographyachieves outstanding line resolution (5 μm width/13 μm spacing). The paste is simple to useperforms comparable of those of major European, AmericanJapanese manufacturers.

Although masks protect us from COVID-19, they cover a substantial portion of the face,eliminates important facial expressions during communications. EmoMask is a human-AI collaborative mask that mediates these interactions in mask-wearing environments through emotion-aware sensorsAI algorithms, which works with humans to create facial expressions. The EmoMask system identifiesdifferentiates expressions using TinyML-based AI algorithm,conducts real-time classificationsregressions to create matching facial expressions during a communication while faces are covered.

A technique compatible to IC process has been presented to prepare gas sensing chips the lightly-doped region of nanoelectronic devices are grown with different sensing materials to form a gas sensor array. During gas sensing, individual nanodevice was Joule-heated, reducing power consumption to microWatts/device, solving the current high power consumption problem. With self-calibration of temperature, humidityinterfering gas, problems like cross-sensitivity, quantification, specificitysensitivity are solved. A demonstration of I+Nose with smart phone was presented for CO detection.
