Poor crystallinity
WebApr 7, 2009 · Furthermore, the self-assembled alkane layers have superior crystallinity and wide band gap, so they have little effect on the transmittance. However, the limitation of this method is that defects in graphene which are larger than the length of the alkane molecule might not be covered, because absent molecule-graphene interaction impedes alkane self … WebDec 29, 2024 · HDPE Shrinkage The crystallinity of HDPE means the shrinkage is high: about 0.015 – 0.04mm/mm or 1.5 – 4%. This will depend on the degree of orientation and the level of crystallinity in the part. That, of course, depends on the processing conditions and even the design of the part that you plan to manufacture.
