用於可穿戴電子產品的超細聚苯胺纖維的規模化生產(只有英文版本)

(只有英文版本)High performance conducting polymer fibres are highly demanded in fields from advanced fibrous devices to frontier fabric electronics. Recently, a joint research team, led by Prof. Xiaoming TAO and Dr Yang CHAI, reported a scalable good solvent exchange strategy to produce ultrafine polyaniline (PAni) fibres. This work was published at Nature Communications. The first authors are Dr. Fang Bo and Mr. Jianmin Yan.   Processing conducting polymers into macroscopically fibrous materials makes it possible to translate their nano-object features to human-friendly products in a continuous manner. Primarily due to the large diameters, the performance and expectations of most achieved continuous conducting polymer fibres (CPFs) have been limited by their insufficient electroactive surfaces and weak tensile strength. Tao’s group report a good solvent exchange strategy in a modified wet spinning technique to prepare the ultrafine PAni fibres (UFPFs) at the large scale. Beyond conventional wet spinning protocol, they replaced poor solvents by good solvents as the coagulation bath to decrease the viscosity of gel protofibres, which were subject to an ultrahigh drawing ratio and reduced to an ultrafine morphology. In the modified one-step wet spinning process, they used good solvents as the coagulation bath to realize the mass production of UFPFs. A decreasing of diameter from ~0.1 mm to ~4.7 µm was observed, which is a record small value in the achieved wet-spun CPFs. The ultrafine fibre shows a smooth surface, highly crystallized microstructures, and uniform electrical properties. Moreover, such an impressive drawing ratio enables a very high production efficiency of UFPFs beyond 40 meters per minute.   UFPFs show impressive mechanical performance and energy storage abilities. UFPFs have a modulus of 29.89±5.6 GPa, and a strength of 1080±71 MPa, at least one order of magnitude higher than that of CPFs with larger diameters. They used polyvinyl alcohol (PVA)-H3PO4 gel electrolyte and two UFPF electrodes to construct a micro capacitor to evaluate the electrochemical activity of UFPFs. The area capacitance is between 1008 and 1666 mF cm-2 at the current densities between 0.32 and 3.18 mA cm-2, outperforming previously reported thick CPFs and other electrodes, and approaching to that of PAni nanowires. Benefitting from the favorable energy and charge storage performance of UFPFs, they demonstrated a high-performance all-solid organic electrochemical transistor (OECT), which is very soft, and shows favorable amplification performance with a high on-off current ratio (103) at low voltages (

高效可集成的離子凝膠濕氣發電機

      在全球資源短缺和碳中和的高度需求下,尋找簡單高效的綠色能源轉換技術,實現能源和社會的可持續發展具有重大意義。濕氣發電機利用大氣環境濕氣中的能量直接產生電能,沒有污染物的產生和有害氣體的排放,是能源領域的一個新興的研究熱點。然而目前大多數的濕氣發電機輸出間歇性的電信號和低電流阻礙了實際應用。另外,實現大規模集成和應用依舊是目前研究的瓶頸。     為了解決這些問題,陶肖明教授研究團隊開發了一種凝膠型的濕氣發電機 (ionic hydrogel moisture-electric generator, IHMEG),能夠高效收集空氣中的水汽直接轉換成電能,實現了高效的電流密度和能量產出。這種新型的離子凝膠濕氣發電機不僅可以穩定輸出直流電壓0.8 V超過1000小時,還能產出高電流密度(0.24 mA·cm-2) 和突出的輸出功率密度(W·cm-2)。更重要的是該IHMEG設備能大規模的集成獲得210V的電能輸出,並成功的為許多微電子設備供電,包括電子墨水屏,金屬電沉積裝置,甚至發光二極體陣列。這種凝膠型的濕氣發電機製備工藝簡單,價格便宜,可實現柔性集成,在物聯網(Internet of things, IoT)和自供電的可穿戴電子系統等領域具有巨大的應用前景。相關工作以“Ionic Hydrogel for Efficient and Scalable Moisture-Electric Generation”為題發表在最新一期的《Advanced Materials》(https://doi.org/10.1002/adma.202200693)。文章第一作者是博士畢業生楊素。

卓越研究:拉脹紡織品

拉脹紡織品是一種擁有非傳統特性的纖維性材料,它彎曲時會呈現雙曲線形狀,以及具備高抗凹壓、高能量及震動吸收的能力。這種材料獲廣泛應用於紡織服裝中,例如功能性服裝、防撞設備、醫療護理儀器以及智能可穿戴裝置等。 具有負泊松比的拉脹紡織品在拉伸時會向各個方向膨脹,擠壓時則會收縮。拉脹紡織品材料具有高度的舒適性和靈活性,可應用於在服裝設計。 智能可穿戴研究院成員,紡織及服裝學系胡紅教授透過採用包括紡紗、針織、機織和編織在內的不同類型的紡織技術來改變纖維集合體的結構,研發出一系列拉脹物材料,包括拉脹紗線、拉脹布料和拉脹紡織複合材料。 由於這些新開發的拉帳物料都是源自實驗室,在產初期,團隊遇到不少挑戰,包括缺乏能生產商用、具有復雜的纖維結構的拉帳紡織物的設備。然而,這些挑最終啓發了胡教授自行研發新的生產設備。 此外,由於巿場上並無類似的生產工藝可供參考,因此生產拉帳物料的過程必需經過專門設計。初期因產能有限,導致可用拉脹紡織品供應短缺,限制了商業終端產品的大規模生產。 目前,隨著研究團隊累積了更多實際的生產經驗,他們已推出了更多適合商用的優質拉脹紡織品,同時胡教授的研究亦已經應用於醫療、運動、功能性及防護性服裝,以及可穿載的科技產品等範圍。

李鸝教授團隊研發出新型遠紅外線纖維(只有英文版本)

(只有英文版本)Prof. Lilly Li, a member of RI-IWEAR, has developed a new way of producing fibres that can absorb and emit far-infrared (FIR) radiation more efficiently than conventional methods. The novel technology can be used to produce high-quality, functional apparel and healthcare products. Unlike the traditional method, Prof. Li’s innovative approach is chemical-free. It is more eco-friendly and cost-effective than the traditional one. It works by modifying the structure of the cross-section of man-made fibres from a conventional circular shape to a triangular one, which is significantly better at both FIR absorption and emission.   The innovation has won Prof. Li a Gold Medal and a Special Merit Award (the Best International Invention, National Research Council of Thailand) at the 47th International Exhibition of Inventions of Geneva 2019 and a Gold Award at the 4th China (Shanghai) International Exhibition of Invention and Innovation 2021.    Please click Excel x Impact Issue 6 to view more detail about the report.

紡織電子交互系統獲得中游研究計劃資助(只有英文版本)

(只有英文版本)Prof. Xiaoming TAO, Director of RI-IWEAR, and Dr Yang CHAI,  recently have secured  approximately HK$5 million under Midstream Research Programmes for Universities from the Innovation and Technology Fund (ITF)  for a 3-year research project entitled “Key Technologies for Textile Electronic Interaction System”.   Human-computer-environment interaction technology has been a recent hot research topic as a result of its applications in smart cities, IoT, AI, VR/AR, and robotics. Interactive textile electronic systems may provide suitable platforms because of their excellent wearable performance and unique immersive features such as lightweight, large-area, handiness, flexibility, comfort, and low strain even under high deformations.   The key to extend the use of these textiles is to develop new technologies for textile-based interaction systems. The project proposes to develop the new technologies by demonstrating prototype system products comprising a modularized fabric display of over 16 million colors, audial communication, fabric keyboard, memory, wireless communication unit and a control unit. In this project, the processing methods for the surface enhancement of flexible fibrous substrates, and fabrication of new double-sided fibrous circuit boards will be investigated. Essential machines and tools will be developed for manufacturing the fabric electronic modules made from electronic yarns, and interconnection between textile electronic modules, as well as determination of processing parameters, quality control methods and procedures. By using the newly developed processes, machines, and tools, Their team will demonstrate novel electronic textile display products for human-computer-environment interaction in smart homes.
