As the crystalline/amorphous ratio of the polymer increased, the dielectric breakdown strength was reduced. The electrical conductivity of the material was also shown to decrease with increasing ...

The average molecular weight of these long polymer chains, as well as their density, crystallinity, molecular mass distribution, degree of cross-linking and the addition of any stabilizers or ...

The work is published in the journal Macromolecules. In general, imparting high crystallinity to polymers is an effective method for improving the strength and durability of the materials ...

As for C1 polymers, whereas highly stereoregulated polymers with high crystallinity have been reported, atactic C1 polymers are amorphous with a relatively low melting point, as well. In this ...

Compared with the other two polymer acceptor materials, PY-Se exhibits higher crystallinity, which can be attributed to the stronger intermolecular interaction between PY-Se molecules. Next ...

Polymer crystallinity has a huge impact on the physical properties including melting point, density, permeability and storage modulus. Therefore, it is important to understand the extent of ...

Atomic Force Microscopy (AFM) is an established nanoscale imaging technique, offering a topographic map of a surface sample high spatial resolution. The main drawback, until recently, of using AFM has ...

Despite their several well-known drawbacks, the devices where polymers are employed as the donor are still leading the OSC universe in terms of performance. Such performance generally depends upon ...

Developing at the point of solidification, the nanostructure of this semi-crystalline state affects the mechanical and physical properties of the polymer product significantly. Therefore, it is ...

For each polymer, the physicochemical properties (compression, crystallinity, surface chemistry, hydrophobicity, and surface topography) were compared before and after exposure under controlled ...
