Nanofabulous Seminar: Functional micropatterned nanocellulose materials: exploring size, composition, resolution and applications
With the increasing interest, awareness and desire for change, consumers are leading the drive to create products with a lower impact on the natural environment along with being sustainable, recyclable and reusable. Cellulose, the world’s most abundant naturally occurring polymer, is a prime candidate to meet these needs due to it being renewable, recyclable and environmentally friendly. These properties lead cellulose to be highly useful in areas of paper-based diagnostic or fluid handling devices. Traditionally, these devices have been fabricated with techniques such as laser cutting, wax printing or microembossing which have the downfall of lower resolution feature sizes.
We have combined fabricating moulds at MCN with a spray coating process to create micropatterned nanocellulose films. We have modified the size of the cellulose components and suspension composition to achieve minimum feature sizes an order to two orders of magnitude smaller than the traditional techniques for paper-based systems. We will also demonstrate applications for these materials in areas such as fluid handling and controlling paper wettability.
