“…XRD analysis was performed using an analytical apparatus equipped with mono achromatized function at 40 KV and a current of 15 mA with Cuα radiation (λ = 0.154060 nm) and the sample was analyzed using a double crystal wide angle geometry with the 2θ scan from 10-90°. The XRD is used to determine the structural properties, to identify crystalline phase and orientation, how the atoms pack together in the crystalline state (atomic arrangement), and what the angle and interatomic distance are, etc [ 23 , 24 ]. Therefore, X-ray diffraction has become an essential and powerful tool for structural characterization in solid-state substances.…”

Herein we demonstrate that polyethylene-like bioderived, biodegradable, and fully recyclable unbranched aliphatic polyesters, such as PE-2,18, develop hexagonal crystal structures upon quenching from the melt to temperatures <∼50 °C and orthorhombic-like packing at higher quenching temperatures or after isothermal crystallization. Both crystal types are layered. While all-trans CH 2 packing characterizes the structure of the orthorhombiclike form, there is significant conformational disorder in the staggered long CH 2 sequences of the hexagonal crystals. On heating, the hexagonal crystals transform to the orthorhombic type at ∼60 °C via melt recrystallization, but no change is apparent during heating samples with the orthorhombic form up to the melting point (∼95 °C). The hexagonal structure is of interest not only because it develops under very rapid quenching from the melt but also because under uniaxial tensile deformation it undergoes a stretch-induced transformation to the orthorhombic structure. Compared to deformation of orthorhombic specimens that maintain the same crystal type, such transformation results in larger strains and enhanced strain hardening, thus representing a desired toughening mechanism for this type of polyethylene-like materials.
