Therefore, multifunctional superamphiphobic coatings/materials with strong mechanical and chemical stability are highly desired. Herein, a simple and flexible approach to produce multifunctional superamphiphobic poly(ethylene terephthalate) (PET) textiles was reported. First, dual micro/nanostructures on the PET fabric surface are constructed by hydrolysis of trimethoxymethylsilane, N-octyltriethoxysilane, and trimethylchlorosilane, and further modified by 1H,1H,2H,2H-perfluorodecyltriethoxysilane and poly(vinylidene fluoride). The as-obtained superamphiphobic PET fabrics show high liquid repellency to water, oil, organic liquids, and strong acid or alkali solutions, exhibiting a water contact angle (WCA) of 161° and an oil contact angle (OCA) of 156°. Meanwhile, the superamphiphobic PET fabrics show strong abrasion resistance; even after 180-cm consistent abrasion, the WCA still maintains 148° and the OCA maintains 140°. Importantly, the fabrics maintain their excellent superamphiphobic property after long-term UV irradiation or ultrasonic treatment, respectively. Because the prepared fabrics have multifunctional features and are easy to fabricate with low cost, they show great potential for self-cleaning, antifouling, anti-icing, drug reduction, corrosion resistance, and protective uniforms.

This work investigated, both experimentally and numerically, the factors that affect flow erosion and part deformation in film inset molded products. Three plate-with-thickness-variation geometries, namely flat, thin-to-thick, and thick-to thin, were molded for the products. Polystyrene films and polyethylene terephthalate (PET) resins were employed in the experiments. It was found that the thin-to-thick specimens exhibited the most severe flow erosion. Increasing the injection pressure or melt temperature worsened flow erosion. Meanwhile, for the processing parameters adopted in the experiments, part deformation generally increased with melt temperature and hold time, while it decreased with injection pressure and hold pressure. Additionally, a numerical software (Moldex® 3-D) was employed to simulate the temperature and shear stress distributions in molded products. The calculated results suggested that part deformation in insert molded products results mainly from the non-uniform temperature profile during the cooling stage, owing to the product configuration and the insert film, while flow erosion is induced by the high shear stress of the polymer melt in the filling stage.

Taguchi, Méthodes de (Contrôle de qualité)Index. décimale : 668.9 Polymères Résumé : This report studied, both experimentally and numerically, the factors affecting the warpage in in-mold decoration (IMD) injection molded parts. All experiments were conducted on an 80-ton injection-molding machine. The materials used in the experiments included poly(ethylene terephthalate) (PET) films and 30 % glass fiber-filled PET resins. U-shaped plate parts with three different angles (90°, 135°, and 150°) at the corners were molded. The influence of various processing parameters on part warpage was investigated using an experimental matrix, with its design based on the experimental-parameterdesign method developed by Taguchi. The experimental results suggested that all molded parts warped toward the side of the decoration film. For the parameters selected in the experiments, the corner angle and the melt injection pressure were found to be the principal factors affecting the warpage of IMD injection molded parts. The 90° angled parts exhibited the greatest amount of warpage, while the 150° angled parts showed the least amount of warpage. Additionally, a commercially available code (Moldex® 3-D) was used to simulate the temperature distribution during the filling process and the molded part warpage. Calculated warpage satisfactorily matched with the experimental data. It has been shown that the warpage of IMD injection molded parts is mainly caused by the imbalanced temperature distribution during cooling, due to the part geometry and the decoration films.
