Kursspecifika förkunskaper

Courses in chemical and mechanical engineering.

Syfte

The aim of this course is for the students to gain knowledge of biopolymers and biocomposites which are used as structural materials. The intention of this course is to bridge gap between biology, physics and chemistry and therefor this course is suitable for chemists, biologists and material scientists. In the course we present biologist's analysis of structural material of organisms, using molecular biology as astarting point. We will explore the chemical structure of biopolymers, illustrating how they composition determine mechanical properties of the materials in which they occur - including skin, artery, plant tissue, stiff composites such as insect cuticle and wood, and biological ceramics such as teefth, bone and egg-shell. Finally we will discuss with students how the design from nature with biomimicry can be applied in developing new "intelligent" materials.

Innehåll

Many material systems found in nature exhibit a combination of properties that is not found in synthetic systems. The unique performance of natural materials arises from precise hierarchial organization over a large range of length scales. These materials display unique properties that are affected by structure and generative processes at all levels of the biological structural hierarchy.The following subjects will be discussed in lectures. Introduction to macromolecules (polymers) Basic material properties Theory of Elasticity and Viscoelasticity Structural proteins (keratins, silk, collagen, elastin, resilin and abductin) Polysaccharides Materials based on combination of proteins and polysaccharides Biocomposites (locust tendon, horn keratin, wood and other selected plants) Biological ceramics and biomineralization. Biomimetic materials In addition to series of lectures students will partici-pate in projects in which they will make experi-ments with biological materials such as wood, shells, mussel adhesives, spider silk, bones etc
