Nanoconcepts and Simulations

Nanoconcepts represent self-contained instructional materials focusing on the key ideas in nanoscale science and engineering (NSE) and their applications. Each Nanoconcept contains a general user introduction, main concept, notes, images and/or simulations. A usage guide and connections to general science concepts is also provided to aid integration into the classroom.

Superabsorbent Polymer - Interactive Computational Animations on Nanomaterials

 

Superabsorbent polymers (SAP) are large chain-like molecules that can absorb water up to thousands of times their own weight. Their ability to absorb is strongly related to the surface area of the polymer that is in contact with water. The surface area depends on the polymer particles size. Fine particles result in larger area than coarse particles.

OVERVIEW:
Superabsorbent polymers (SAP) are large chain-like molecules that can absorb water up to thousands of times their own weight. Their ability to absorb is strongly related to the surface area of the polymer that is in contact with water. The surface area depends on the polymer particles size. Fine particles result in larger area than coarse particles.

This animation is classified into two sections: “Basic (high school chemistry or equivalent)” and “Advanced (AP chemistry or college chemistry)”

Required skills: Knowledge of High School Algebra and Geometry

Class: High School Chemistry; AP Chemistry; College Chemistry

Approximate Time: 45 min - 1 hr
