Advanced Materials Explained — A Quick Guide for Non-Scientists
Folks: Madonna isn’t the only one — we all live in a material world.
Everything is made out of something: materials. We encounter them every moment of every day… in fact, we are them. So, what exactly is a material? The most fundamental definition might be: the substance that constitutes a thing. Kind of boring, though… right? Let’s try again.
A material is a substance that has an intended use or purpose. Understanding a material means understanding how its history — or processing — influences its structure to create properties that determine its performance for the intended use. This concept is known as the Materials Paradigm.
Using the Materials Paradigm, we can define Advanced Materials (AMs). AMs are simply improved materials compared to their conventional counterparts or constituents. By manipulating structure and processing, we achieve improvements in properties and performance.
Are AMs a 21st-century novelty? No — in fact, they can be traced back to 3000 B.C.E., when adding other metals (mainly tin) to copper created a material with superior properties: bronze (Materials 2024). This effectively marked the end of the Stone Age. People often associate advanced materials with terms like “new,” “high-tech,” “man-made,” “composites,” and “polymers.” But the truth is much more fascinating. Both nature and human ingenuity have provided examples of ancient composites and polymers.
A Historical Perspective on Materials
Here is the historical perspective of materials according to their relative importance:
And here is a historical timeline of materials and the corresponding ages of civilization:
The material of choice in a given era is often a defining characteristic. Phases such as the Stone Age, Bronze Age, Iron Age, and Steel Age are historical- if somewhat arbitrary — markers. Modern materials science evolved directly from metallurgy, which itself evolved from the use of fire.
Materials science has both driven and been driven by the development of revolutionary technologies such as rubbers, plastics, semiconductors, and biomaterials. Yet when we read headlines about trade wars and supply chain issues involving rare earth metals, few realize the opportunities — or rather, the necessity — of discovering and commercializing advanced materials. Nanomaterials, perovskites, quantum materials, and self-healing polymers all hold enormous strategic implications for both organizations and governments.
Game-Changing Materials in the History of Advanced Materials
Throughout history, certain materials have catalyzed technological revolutions. Here are some of the most pivotal:
Bronze (Bronze Age)
- Impact: Enabled stronger tools, weapons, and early infrastructure
- Technological Leap: Transition from stone tools to metalwork; advanced agriculture, warfare, and urbanization
Iron & Steel (Iron Age to Industrial Revolution)
- Impact: Stronger and more versatile than bronze
- Technological Leap: Foundation of industrialization — railways, bridges, skyscrapers, and machinery
Silicon (20th Century — Electronics Era)
- Impact: Basis for semiconductors and integrated circuits
- Technological Leap: Powered computers, telecommunications, and the digital age
Polymers (20th Century)
- Impact: Lightweight, moldable, and chemically versatile
- Technological Leap: Enabled innovations in consumer goods, aerospace, and healthcare (e.g., bioplastics, implants)
Carbon Fiber / Composites
- Impact: High strength-to-weight ratio, corrosion resistance
- Technological Leap: Critical for aerospace, electric vehicles, and wind turbines
Superconductors
- Impact: Allow zero-resistance current flow
- Technological Leap: Enabled maglev trains, MRI machines, and early quantum computing
Lithium-Ion Batteries
- Impact: High energy density and rechargeability
- Technological Leap: Fueled mobile computing, smartphones, electric vehicles, and renewable grid storage
