Main effects of parameters like melt temperature, quenching air velocity, winding speed, draw ratio, and the position of the bobbin on the coefficient of variation (CV) of the FDY were examined. The interactions between significant factors were detected by the analysis of variance. CCD model showed that the quenching air velocity has no significant effects on the CV values. The special effects of the winding speed and melt temperature are higher than that of draw ratio and the position of the bobbin. Final model predicted the minimum CV values of 1.72–1.78% at 15 melt spinning conditions. Optimal CV value (1.72%) was achieved at the melt temperature of 283.8 °C, quenching air velocity of 41.0 m/s, winding speed of 4391.7 m/min, draw ratio of 2.89, and the position of 0°. It was also revealed that the average tensile strength of the PET filament yarns decreases from 44.73 ± 1.13 to 40.50 ± 0.81 cN/tex as the unevenness increases from 1.8 to 3.0.

Hollow nanospheres of titanium dioxide with a well-defined morphology are prepared by calcination at high temperatures, as the PS spheres completely decompose. Interestingly, highly porous structures, which give rise to high surface area for trapping scCO<sub>2</sub>, are generated on the surface of the TiO<sub>2</sub> nanoparticles during the thermal treatment. The dispersion of TiO<sub>2</sub> nanospheres in the TPU matrix is successful, serving as heterogeneous nucleating agents that influence the cell density and morphology of the extended TPU in the foaming process.</p><h3>Graphical abstract</h3><p>In this study, hollow nanospheres of titanium dioxide (TiO<sub>2</sub>) with unique porous surface are prepared and utilized as potential nucleating agents in supercritical carbon dioxide (scCO<sub>2</sub>) foaming process of thermoplastic polyurethanes (TPUs) to control various foaming parameters including foaming ratio, cell size, cell density etc.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":688,"journal":{"name":"Macromolecular Research","volume":"32 8","pages":"789 - 797"},"PeriodicalIF":2.8,"publicationDate":"2024-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140929281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
