| Abstract Scope |
The following work focuses on the surface modification and processing of soft PLA and PLA-Graphene composites using corona discharge-based microplasma in ambient conditions. The work includes both in-situ and ex-situ-based processing using a proprietary plasma integrated 3D printing system developed in the Energy Devices and Plasma Applications Laboratory at California State University, Fresno. The current-voltage characteristics of the plasma are varied based on the use of a quasi-static DC discharge with a variable voltage of 1 kV to 2.2 kV. The surface characterization of the 3D printed geometries is performed using profilometry and scanning electron microscopy. The surface energy and wettability characteristics are studied using a contact angle goniometer. The electrical properties of the surface are characterized using impedance spectroscopy. |
