Engineering a Dual In-Situ Strategy to Incorporate Organotitanium Nanosheets into Polyethylene Terephthalate for High-Performance Outdoor UV Fabric Shelters — •Hailong Yu, Jia Chen, Xiang Fei, Bin Sun, and Meifang Zhu — State Key Laboratory for Modification of Chemical Fibers and Polymer Materials, College of Materials Science and Engineering, Donghua University, 201620, Shanghai, China

In this study, we employed a dual in-situ approach to integrate organotitanium nanosheets into Polyethylene Terephthalate (PET), aiming to explore their applications in high-performance outdoor UV fabric shelters. Characterization techniques, including SEM, XRD, GPC, TGA, DSC, dynamic oscillatory rheology, and capillary rheometer, were utilized. Notably, the study revealed that the nanosheet structure significantly impacted PET's rheological and crystalline behavior, thereby exerting a profound influence on processing performance. We achieved uniform nanosheet dispersion within PET, enhancing structural integrity. PET/nano-Ti composites displayed outstanding UV resistance, with 80% retained strength after UV exposure, surpassing pure PET (70%). UV-A transmittance was only 2.38%, with UPF exceeding 50. These composites offer a robust choice for UV fabric shelters, including outdoor clothing and tents. This research highlights the profound impact of nanosheet composites on PET's behavior and their critical role in UV resistance, supporting the development of high-performance outdoor materials.
