Summary:
ISU researchers have developed a system for creating colloidal crystals, embedded in a polymer, using a 3D-printer like flow-through system.

Development Stage:
 
Description:
Collodial crystals, ordered structures composed of micro- and nano-scale particles, enable many advanced material applications, such as enhancing solar cell efficiency. Current approaches to colloidal crystal assembly are either limited to directed assembly in a batch process that produces single colloidal crystals or will result in defect formation due to stresses used to increase throughput. Manufacturing defect-free ordered materials is immensely important for many of the optimal applications of colloidal crystals, including solar energy harvesting. Iowa State University researchers have developed a system for 3-D printing colloidal crystals embedded in a polymer in a high throughput manner that produces high-quality, defect-free, composites. The system takes advantage of an applied external field, in this instance an acoustic field, in order to induce self-assembly of the crystals in a fast and cost-efficient manner.

Advantage:
• Cost effective
• Fast
• No clean room needed
• Produces multi-material structures useful for composites and biological materials
