Synthesize Zn(OH)2 via two different chemical methods (bulk and micro-emulsion)
- Determine if there is any visible difference in the characteristics of the product formed in each method
Determine whether there is a difference in the UV-absorbing quality of micro- vs. nano-powders of ZnO
Create a hand-cream (emulsion) base for a sunscreen lotion
Prepare a sunscreen by adding ZnO microparticles to a portion of the hand cream
Test the ability of the sunscreen to absorb UV light.
- Sunscreen and Nanotechnology Lab Activity, including:
- Pre-Lab and Safety/Hazards Assignment
- Background Information
- Student Report Sheet
- SDS: Safety Data Sheets for the Sunscreen and Nanotechnology Lab
