“…In our previous study, the infusion behavior and solvent induced crystallization of PET filament drawn at room temperature at constant drawing speed in ethanol have been discussed [2]. We also confirmed that neither infusion of ethanol nor crystallization of PET filament does not proceed only by immersing low oriented PET filament in ethanol [2].…”

“…In the previous study, amorphous low oriented poly (ethylene terephthalate) PET filaments were drawn in ethanol up to various draw ratios (DR) at a constant drawing speed [2]. At the early stage of drawing multiple necks were observed on filament, while drawing of filament in air or water showed only one neck formation [2].…”

The surface of poly(ethylene terephthalate) (PET) films crystallizes when exposed to a broad class of organic solvents (protic polar, aprotic polar, and non-polar). This phenomenon leads to irreversible changes in transparency and mechanical properties. It also limits PET films and coatings in applications including electronics, medicine, packaging, and construction. This work describes a method to impart solvent resistance to the PET surface by depositing a silicate film. This coating enables many post-functionalization options, including those that tune wettability or impart antifouling characteristics to the parent PET surface. It also endows PET surface resistance to organic solvent exposure without affecting the overall mechanical and optical properties of the PET. Additionally, the silicate layer improves the scratch resistance of PET surfaces.

Sodium citrate (SC) and thermoplastic polyester‐ether elastomer (TPEE) were used as modifiers to improve the crystallization behaviors and mechanical properties of poly(ethylene terephthalate) (PET) via melt blending method, which aimed to resolve the problems of slow crystallization rate, poor toughness, and poor compatibility of blends. The crystallization and mechanical properties of PET/TPEE/SC blends were systematically investigated. The results showed that SC had an effective nucleation effect on PET and TPEE could improve the toughness of PET. For PET/TPEE blends, the crystallization temperature and crystallization rate of PET decreased with the increase of TPEE content, but adding 0.6 wt% SC to PET/TPEE blends would improve the crystallization rate of PET/TPEE/SC blends. The incorporation of SC and TPEE had an effect on the long period, but it had little effect on the crystal structure of PET. Moreover, PET/TPEE/SC blends had good impact toughness and plasticity.
