The FSWPU’s particle size was examined using dynamic light scattering. After the FSWPUs were processed into a dry film, their molecular weight and basic properties were analyzed using gel permeation chromatography (GPC), Fourier-transform infrared spectroscopy (FTIR), and energy-dispersive X-ray spectroscopy (EDS). Additionally, the thermal stability of the FSWPUs was inspected by thermogravimetric analysis and dynamic mechanical analysis. The tensile strength and elongation at the break of the FSWPUs before and after hydrolysis were also analyzed, using a tensile testing machine. Subsequently, FSWPU emulsions were cast between the tiles, and hydrophilicity, hydrophobicity, and surface tension were then measured on a contact-angle measurement instrument. The tensile testing machine was again employed to test the sheer strength of the FSWPUs between the tiles, and a tape test was conducted to analyze their adhesion to the tiles. The results revealed that AEAPTES functional groups can reinforce the thermal stability, tensile strength, and water resistance of FSWPUs. Moreover, the AEAPTES functional groups increased the adhesion of FSWPUs to the tiles and reduced the surface energy of the tiles. 關聯 Sustainability, Vol.12, No.9, pp.1-15 資料類型 article DOI https://doi.org/10.3390/su12093745 dc.contributor 資管系 dc.creator (作者) 洪為璽 dc.creator (作者) Hung, Wei-His dc.creator (作者) Hsu, Yao-Tang dc.creator (作者) Wang, Wen-Hsin dc.date (日期) 2020-05 dc.date.accessioned 26-May-2021 10:41:53 (UTC+8) - dc.date.available 26-May-2021 10:41:53 (UTC+8) - dc.date.issued (上傳時間) 26-May-2021 10:41:53 (UTC+8) - dc.identifier.uri (URI) http://nccur.lib.nccu.edu.tw/handle/140.119/135149 - dc.description.abstract (摘要) This study successfully synthesized fluorinated silicon-containing waterborne polyurethanes (FSWPUs) by using polycaprolactone (PCL) diol, 2,2,3,3-Tetrafluoro-1,4-butanediol, and [3-(2-Aminoethylamino)propyl] trimethoxysilane (AEAPTES ).
