Abstract

Engineering Engineering, Mechanical Science & Technology Technology
This review describes the transport processes in evaporation-driven self-assembly of colloidal drops containing functional materials for printable electronics fabrication. The jetting of solution-processed functional materials involves drop formation, impact, wetting, carrier liquid evaporation, and particle self-assembly and deposition, in which the interplay determines the final mechanical, thermal, and electrical properties of the deposited electronic materials. The capillary-driven, non-uniform deposition of functional materials challenges the quality of printable electronics that often require uniform patterns to achieve high performance. Several approaches have been introduced to suppress the coffee-ring effect. Numerical modeling to directly simulate particle-particle, particle-liquid, and particle-substrate interactions, and to predict final morphology of deposition patterns is discussed to better understand and control inkjet printing of colloidal drops for printable electronics fabrication.
