- Green printing
- Encapsulation, delivery, remediation, and sensing in food and personal care industries, for drug and gene delivery, and as underwater adhesives
- Purely aqueous processing without the need for any organic solvents
- Printed coacervate materials are robust when exposed to solvents and elevated temperature (stable up to 450℃)
This invention provides a cost effective and environmentally friendly printing method with an “ink” that is based on a class of polymer-rich liquids, termed complex coacervates. The fully aqueous nature of coacervate-based materials avoids the need for purification or post-processing to remove toxic organic solvents and enables technology for much desired green printing. The low surface tension of coacervates with water has also facilitated their use as encapsulants in the food and personal care industries, for drug and gene delivery, ad as under water adhesives.
