Oleophobic Surfaces - Anti-Graffiti Demo

  • coating demonstration
NISE Network product
Description
Oleophobic Surfaces - Anti-Graffiti Demo is a hands on cart demonstration for spontaneous, 3-10 minute interactions with visitors. The visitors will explore several surfaces that display oleophobic properties due to material science research at the nano scale. Coatings can preserve, protect, lubricate, grip, and a myriad of other behaviors. For example, walls can be coated with material that when dry, will prevent the adhesion of paint or ink. In this demonstration, we're examining coatings that are oleophobic, "oil hating," and prevent low surface tension liquids from adhering to it.

Objectives

Big Idea

Scientists research surface treatments for materials in order to illicit a specific behavior from the material's surface. Coatings can preserve, protect, lubricate, grip, and a myriad of other behaviors. For example, walls can be coated with material that when dry, will prevent the adhesion of paint or ink. In this demonstration, we're examining coatings that are oleophobic, "oil hating," and prevent low surface tension liquids from adhering to it.

Learning Goals

As a result of exploring this demonstration, visitors will learn that oleophobic means "oil hating."

As a result of exploring this demonstration, visitors will be able to appreciate that scientists have created oleophobic surfaces using nanomaterials.

As a result of exploring this demonstration, visitors will be able to identify several applications for oleophobic surfaces.

Nano Content Map
Nanometer-sized things are very small, and often behave differently than larger things do.
Scientists and engineers have formed the interdisciplinary field of nanotechnology by investigating properties and manipulating matter at the nanoscale.
