Film coatings

Project summary

Liquid coatings deliver medicines to human tissue, pesticides to plant surfaces, and surface modifiers to industrial materials. More efficient coating requires greater resistance to flow, but high viscosity fluids produce poor sprays and mists in medical and other spray devices. Nanocellulose is a unique, biologically compatible, material that can enhance coating efficiency by orders of magnitude while not adversely affecting spray performance. This project will study the mechanism of coating modification by nanocellulose and measure its ability to deliver active materials to plants and other biological surfaces.

Project objectives

  • Measure flow properties in sprays and spread films
  • Study interactions with biological surfaces like plant leaves and human skin/tissue
  • Measure delivery of active ingredients like pesticides and drugs to target surfaces
