Intercrystalline links

The individual spherulite lamellae are bound together by tie molecules that are present in more than one spherulite. Sometimes these tie segments form intercrystalline links, which are threadlike structures, that are important in developing the characteristic good toughness found in semicrystalline polymers. They act to tie together the entire assembly of spherulites into a more or less coherent package. ...

In case of the use of polycrystalline adsorbent subject to high temperature oxidation and characterized by almost stoichiometric content of the surface its electric conductivity can be linked with penetration of the current carriers through high intercrystalline barriers. The effect of adsorption on electric conductivity of adsorbents of such type is mainly manifested through the change of heights in intercrystalline barriers controlled by the value of the surface charge. 

The structure of high modulus polyethylene fibres obtained by optimized drawing of linear polyethylene is viewed as crystalline lamellae linked by intercrystalline bridges.Accordingly, the component B is then viewed as crystalline, and its content (1 — >1) corresponds to the volume fraction of the material incorporated in the crystalline bridges. A more complex model consisting of four components has been proposed for these fibres by Grubb.
