Materials Chemistry

Materials Chemistry is the examination of chemical synthesis and its application in the discovery of new materials. It specifically looks at novel chemical principles being applied at the molecular level, to create new materials with novel properties. Materials Chemistry is an unconventional topic in the subject of Chemistry, as it is not limited or confined to a certain discipline. It not only combines the different sub-disciplines of chemistry, such as organic, inorganic, physical and analytical chemistry, but also extends into different subjects such as biology, physics and engineering. Thus, chemists who are successful in Materials Chemistry must disregard the traditional barriers between disciplines, and be able to navigate easily across the different subjects. One application of Materials Chemistry is the improvement of bodily and physiological functions. For example, a new class of metal-organic frameworks has been discovered, which consist of metal vertices and organic linkers that form porous structures (1). The extended porosity of these structures renders it more efficient for gas storage and pharmaceutical delivery within the body. Although Materials Chemistry is a relatively new field, it is starting to become a major focus as its applicability extends beyond the realm of chemistry. Thus, examining how different molecules combine to result in different properties is crucial for the synthesis of new and useful materials. Reference: (1)

Polymer Chemistry is the examination of chemical properties of polymers and its applicability in the synthesis of new macromolecules.

Short question

A brittle sample of polystyrene behaves elastically in tension, until it breaks in two when extended 2.2%, under a load of 55MPa. What is the toughness of this sample? i know i may use the stress strain curve to solve this problem? (Force vs elongation)... but how do i solve the toughness of the sample?

Glass Transitions of Copolymers

Homopolymer A has a Tg of 80C, homopolymer B has Tg of 70C. Estimate Tg of a 30/70 random copolymer of A and B. What assumptions should be made? Compare all relationships that can be used and discuss which is more accurate.
