🎯 Why This Domain Matters#

Polymer science at NIST supports:

• reference data for industry and standards bodies
• predictive models for rheology, crystallization, and degradation
• advanced composites for electronics, energy, and manufacturing
• environmental and recycling pathways for plastics
• polymer informatics and autonomous materials discovery
• soft‑matter metrology across nano‑ to macro‑scales

It is one of the most experimentally diverse and application‑rich NIST domains.

🎓 How This Primer Is Used#

This overview prepares students for:

• regime_alignment.md — mapping R0–R3 structure
• student_exercises.md — short reasoning tasks
• triadic_awareness.md — connecting TF to polymer‑metrology work

It doesn’t attempt to summarize all 1,930+ publications — only to give a clear, respectful starting point grounded in the domain’s visible structure.
