项目摘要
Advanced nanofabrication is a hotspot in the manufacturing and nanotechnology industries. Nanofabrication using ultrashort laser pulses offers unique advantages over other approaches. It is single-step and can be applied to a wide range of materials. My proposed research program will focus on a novel ultrashort laser ablation technique that is capable of preparing 3D nano-network structures with controlled optical and chemical sensitivity and enhanced biocompatibility. The fabricated structures will be immediately usable in different applications such as super capacitor and battery electrodes, photonic devices, nano-sensors and bio-functional material fabrication. Pulsed laser ablative machining has traditionally been used for machining and material removal at micro- and sub-micro scales; due to its low efficiency, however, it is rarely used for nanomaterial synthesis. Laser-based nanomaterial synthesis normally employs high-powered continuous lasers and nanosecond lasers, and requires catalysts and a controlled environment. At megahertz laser-pulse frequency, however, the delay time between successive pulses is comparable to the critical time of nucleation, which enables the formation of nanostructures in ambient conditions without the addition of a catalyst. The main objective of my proposal is Laser 3D Nanonetwork (nanowires, nanofibrous structured) generation. I intend to extend my research on the fundamentals of ultrashort-laser-matter interaction at the MHz-pulse frequency range and the mechanisms of 3D nanonetwork formation. My goal is to use the knowledge I acquire to develop cost-efficient and controllable processes for synthesizing nanomaterials and 3D nanostructured surfaces on a larger scale. This includes the study of the effects of laser parameters, environments and external fields on the formation of various nanomaterials, such as nanorods, nanotips, and nanofibres. Anticipated outcomes: The research supported by this grant will be aimed at developing an understanding of high frequency/high intensity pulse ionization mechanism in nanofabrication and develop cost-efficient and controllable processes for synthesizing advanced sensing materials, energy nanomaterials and biomaterials fabrications at a larger scale. This includes the study of the effects of laser parameters, environments, and external fields on the formation of various nanomaterials and their properties for different applications from advanced sensing structures to energy storage devices and biomaterials fabrication. The personnel trained under this program will acquire a valuable skillset in nanofabrication and materials characterization that will make them suitable for careers in Canada's expanding advanced manufacturing and biotech sectors.
先进纳米加工是制造业和纳米技术行业的热点。使用超短激光脉冲的纳米制造比其他方法具有独特的优势。它是单步的,可应用于多种材料。我提出的研究计划将重点关注一种新型超短激光烧蚀技术,该技术能够制备具有受控光学和化学敏感性以及增强的生物相容性的 3D 纳米网络结构。所制造的结构将立即用于不同的应用,例如超级电容器和电池电极、光子器件、纳米传感器和生物功能材料制造。 脉冲激光烧蚀加工传统上用于微米和亚微米尺度的加工和材料去除;然而,由于其效率低,它很少用于纳米材料的合成。基于激光的纳米材料合成通常采用高功率连续激光器和纳秒激光器,并且需要催化剂和受控环境。然而,在兆赫激光脉冲频率下,连续脉冲之间的延迟时间与成核的临界时间相当,这使得能够在环境条件下形成纳米结构,而无需添加催化剂。 我的提案的主要目标是激光 3D 纳米网络(纳米线、纳米纤维结构)的生成。我打算扩展我对 MHz 脉冲频率范围内超短激光与物质相互作用的基础知识以及 3D 纳米网络形成机制的研究。我的目标是利用我获得的知识来开发具有成本效益且可控的工艺,以大规模合成纳米材料和 3D 纳米结构表面。这包括研究激光参数、环境和外部场对各种纳米材料(例如纳米棒、纳米尖端和纳米纤维)形成的影响。预期成果:这笔赠款支持的研究旨在加深对纳米制造中高频/高强度脉冲电离机制的理解,并开发具有成本效益且可控的工艺,用于大规模合成先进传感材料、能源纳米材料和生物材料制造。这包括研究激光参数、环境和外部场对各种纳米材料形成的影响及其在从先进传感结构到能量存储设备和生物材料制造等不同应用中的特性。根据该计划接受培训的人员将获得纳米制造和材料表征方面的宝贵技能,这将使他们适合在加拿大不断扩大的先进制造和生物技术领域从事职业。
