Molecular orientation of spider silks in the natural and supercontracted states

摘要: Two theoretical models are presented to predict average molecular orientation properties of spider silk which has unknown and chemical structure. Birefringence elongation (or shrinkage) data required for two distinct lengths a sample in order fit the data. The first model is based on assumptions that each molecule behaves as deformations affine. second random distribution molecules fiber formed affine when elongated any length. Data were taken from silks natural state shrunken (due water). gives much better applicable other systems.
