Direct Writing of Functional Layer by Selective Laser Sintering of Nanoparticles for Emerging Applications: A Review

Abstract

Selective laser sintering of nanoparticles enables the direct and rapid formation of a functional layer even on heat-sensitive flexible and stretchable substrates, and is rising as a pioneering fabrication technology for future-oriented applications. To date, laser sintering has been successfully applied to various target nanomaterials including a wide range of metal and metal-oxide nanoparticles, and extensive investigation of relevant experimental schemes have not only reduced the minimum feature size but also have further expanded the scalability of the process. In the beginning, the selective laser sintering process was regarded as an alternative method to conventional manufacturing processes, but recent studies have shown that the unique characteristics of the laser-sintered layer may improve device performance or even enable novel functionalities which were not achievable using conventional fabrication techniques. In this regard, we summarize the current developmental status of the selective laser sintering technique for nanoparticles, affording special attention to recent emerging applications that adopt the laser sintering scheme.

A review of hierarchical porous carbon derived from various 3D printing techniques

“…Selective laser sintering is a representative direct writing method. 97 Luo et al 98 reported a facile and scalable direct laser writing (DLW)-assisted technique for generating porous carbon platelets (PCPs) with uniform size and arbitrarily designed shapes. This innovative approach leverages CO 2 laser irradiation to induce carbonization of a biomass composite sheet.…”

Rapid Printing of High-Temperature Polymer-Derived Ceramic Composite Thin-Film Thermistor with Laser Pyrolysis

“…The laser process has the advantage of selective processing, low thermal damage to the substrate, and applicability to complex conformal structures. Moreover, a laser can be faster and more conveniently applicable to various substrates than a furnace, − which can help optimize conventional methods. Laser pyrolysis of organic polymers (polysilazane/polydimethylsiloxane) has been applied to fabricate multiple ceramic coatings, , sophisticated polydimethylsiloxane microstructures, − and flexible sensors. − Laser reductive sintering has been demonstrated to fabricate highly sensitive temperature sensors .…”
