❓ Frequently Asked Questions
What is materials science?
An interdisciplinary field that studies the structure, properties, and processing of matter to design materials with specific functions, bridging physics, chemistry, and engineering.
What are polymers?
Polymers are large molecules made of repeating subunits (monomers). They can be natural or synthetic and offer a wide range of properties used in many applications.
What are thermoplastics, thermosets, and elastomers?
Thermoplastics soften when heated and can be remolded; thermosets cure permanently and become hard; elastomers are highly elastic polymers that stretch and return to their original shape.
How do scientists tailor polymers for specific functions?
By selecting monomers, controlling chain length and branching, introducing crosslinks, adding fillers or additives, and choosing processing methods to achieve desired mechanical and thermal properties.
