“…It should be noted that the crystallinity of PET is related to the concentration of the additive 43 . Initially, an increase in concentration accelerates nucleation speed leading to increased crystallinity, 44 which reaches its peak value at 0.75 wt%. However, further increase in concentration results in poor dispersion of additives causing agglomeration, expansion between the crystal nuclei gaps, defect formation, and inability to refine the crystal nuclei, consequently resulting in decreased overall crystallinity levels observed 45 …”

In this work, innovative hybrid poly(ethylene terephthalate) (PET) materials with strong luminescence were successfully synthesized by doping PET with silicon‐linked poly(ethylene glycol)‐PET copolymer nanostructures either with (Si‐PEG‐PET) or with (ETP@Si‐PEG‐PET) luminescent Eu3+‐complexes. The chemical properties and nanostructures of the hybrid materials were characterized by Fourier‐transform infrared spectroscopy, nuclear magnetic resonance spectroscopy, x‐ray photoelectron spectroscopy, and high‐resolution transmission electron microscopy. PET composites ranging from 0.25 to 4 wt% silicon additive were prepared by the melt blending method. The crystal properties, mechanical properties, and fluorescence properties of the composites were systematically studied by differential scanning calorimetry, x‐ray diffractometry, tensile testing, and fluorescence spectrometry. When the addition of Si‐PEG‐PET or ETP@Si‐PEG‐PET was 0.75 wt%, the relative crystallinity and maximum tensile strength increase substantially. Moreover, the fluorescence intensity of hybrid luminescent PET materials is the strongest at 0.75 wt% loading. ETP@Si‐PEG‐PET not only endows PET polyester with stronger fluorescence properties and mechanical properties but also acts as an effective nucleation additive for PET.Highlights Silicon‐linked poly(ethylene glycol)‐poly(ethylene terephthalate) (PEG‐PET) nanostructures generate hybrid luminescent PET materials. ETP@Si‐PEG‐PET improves the crystallization rate and crystallinity of PET. The composite with 0.75% addition showed the best fluorescence performance. Three‐dimensional‐grid structure of ETP@Si‐PEG‐PET enhances the mechanical property of PET.

The quality of epoxy composites reinforced by glass fibers and manufactured by compression molding is affected by the pressurization time. Traditional methods, including differential scanning calorimetry and dynamic thermomechanical analysis, cannot be reliably used to predict pressurization time in the scenario of continuous production and inconstant circumstances seen in industry. In this paper, the rheological behaviors of epoxy under constant temperature were investigated and analyzed to verify if the time–temperature superposition (TTS) principle, which defines the relation between time and temperature in the deformation and relaxation response of a viscoelastic material, could be suitably applied to describe them. The results show that the TTS principle could indeed be used to predict resin viscosity by the horizontal shift factor. A new method based on the TTS principle and written into a program to forecast pressurization time in compression molding is proposed. The uniform surface color and the qualified thickness of the composite components using the program indicate that the program works well and that this method is feasible for predicting pressurization time during compression molding. The results of tensile and short‐beam shear strength tests show that pressurization time affects the mechanical properties of the final product. © 2018 Wiley Periodicals, Inc. J. Appl. Polym.
