Title of Speech: Novel composite materials and their advanced manufacturing technologies
Abstract: This presentation illustrates the current development of novel graphene-based composites such as SiC-graphene core-shell nanoparticles, Al2O3-SiC-GNS composite and Al alloy-SiC-GNS composite. Microstructures, wear scar-topographies and mechanical properties are analysed and evaluated in both qualitative and quantitative manner. For instance, Al/Si-SiC-graphene disks fabricated using this innovative technology have achieved a much greater hardness compared with the conventional Al/Si disks, and then demonstrates several advanced manufacturing technologies based on composite materials, including the manufacturing of micro drill using HSS and WC, micro deep drawing of Cu/Al composite and the pump body forming. Appropriate methods like theoretical analysis, numerical simulation and physical experiment have been employed to investigate these forming processes accordingly, and the material formability as well as the shape, surface quality and tribological properties of the products has also been estimated and analysed, whereof the results have proved the feasibility and efficiency of the newly developed technologies. Finally, concluding remarks are given to summarise the aforementioned contents.

Speech Title: Advances in Materials and Manufacturing Processes for Printing Flexible Electronics
Abstract: Printed flexible electronics refer to applications of printing technologies for fabrication of various electronic devices on flexible substrates, which have attracted increasing attention in the field of wearable sensors, transparent conductive films (TCF), thin film transistors (TFT) and radio-frequency identification (RFID) tags. This invited presentation provides an overview of recent advances in research and applications of printing materials and relevant manufacturing processes used in flexible electronics.
Currently, various emerging manufacturing technologies by printing, such as ink-jet printing, screen printing, direct ink writing and gravure, have been demonstrated to be appropriate for fabrication of above flexible electronic devices. Notably, as a non-contact printing method, drop-on-demand ink-jet printing has great potential for fast and large-scale production. Meanwhile, screen printing of conductive inks is also widely used to fabricate two-dimensional (2D) electronic devices due to its low cost. Significantly, the main functional component of the inks for the above manufacturing processes is the conductive filler material, which can be metal nanomaterials, carbon nanotubes, graphene, conductive polymers and organometallic complexes. Among them, the metal nanomaterial ink with excellent conductivity is still most widely used for printing technologies.
Typically, the insulating capping agents and other additives in metallic nanoparticle inks should be removed through different post-printing treatments such as thermal sintering, photonic sintering and chemical sintering for achieving desirable physical properties. However, the damage of flexible substrate may occur due to the temperature rise caused by such sintering treatments. Thus, developing printable inks capable of sintering at low temperature is highly demanded for fabrication of flexible electronics on different flexible substrates. Additionally, the heat sensitive substrates should also be seriously considered during manufacturing processes. Furthermore, the high cost of silver and electromigration of silver atoms inevitably limit applications of silver ink in printed flexible electronics, then another major challenge is to replace silver (noble metal) ink with cheaper ones, such as copper or aluminum nanoparticles. Therefore, in order to fabricate flexible electronics with enhanced portability and reliability, the optimal selection of conductive ink materials, substrates and manufacturing processes is of great importance.
