Materials World Modules

An Inquiry & Design-Based Science, Technology, Engineering, and Mathematics (STEM) Education Program

Mini Nanopatterning Module

Patterns and Scaling
Double Replica Molding

Design Project
Prototype OLED Array

Through the following key select activities, students will learn how to visualize and fabricate patterns at the micro and nanoscales. The will see examples of these patterns and learn about their applications. When they complete the Activities, they will be ready for the Design Project in which they will fabricate, test, and evaluate a prototype pixel array.

MWM will give students an opportunity to understand the world around them in a way they have never experienced before. The modules promote an awareness of the roles science and technology play in society and guide students to take increased control of their work.

Activity 4: Patterns and Scaling
Students will make their own ‘master’ patterns using Shrinky Dink plastic. After designing creative two-dimensional patterns, students must use appropriate scaling to create a diffraction grating pattern of a particular size. Finally, they will make molds of the patterns and of a CD grating to use in the next activity.

Activity 5: Double Replica Molding

Students use the molds they made in Activity 4 to make replicas of their original patterns on flexible substrates. By molding both sides of the substrate students can create patterns with more complex diffraction patterns.

Design Project: Prototype OLED Array

Based on the techniques they learned in the Activities, students will design and then fabricate a prototype of a pixel array on a flexible substrate. They will also develop evaluation criteria and perform tests on their prototypes,
the results of which will be presented in class.
