Colorless polyimides with excellent thermal and mechanical properties were developed from 2<italic>R</italic>,5<italic>R</italic>,7<italic>S</italic>,10<italic>S</italic>-naphthanetetracarboxylic dianhydride, their systematically compared those based on 1<italic>S</italic>,2<italic>R</italic>,4<italic>S</italic>,5<italic>R</italic>-cyclohexanetetracarboxylic dianhydride.
Colorless polyimides with high glass transition temperatures (up to 440 °C) were developed from three adamantane-containing diamines, and the structure–property relationship of this series was established.
Abstract Biodegradability is a crucial indicator to evaluate the sustainability of leather. Herein, rapid method for biodegradation test in an aqueous medium by measuring biochemical oxygen demand was used determine biodegradability leather from different tanning methods, conditions and process stages. In addition, difference between leather-like synthetic materials were investigated. Chrome-free tanned showed higher degree faster rate than chrome Among them, leathers with biomass-based...
The development of a clear relationship between the multiphase mechanical properties composites and nanomechanical response is major challenge. Most current studies focus on prediction single-phase while neglecting interactions multiphases in composites. To further improve performance ability TiCp/Fe composites, fundamental understanding how matrix phase influence reinforced necessary. In this study, data-physics hybrid-driven model considering proposed to predict TiC particles. addition,...
In this work, a series of fluorene-based polyimide resins with pendent and endmost phenylethynyl groups were synthesized using 9,9-Di[4-(3,4-dicarboxyphenoxy)phenyl]-4,5-diazafluorene dianhydride (BPF-PA) aromatic diamines ((3,5-diaminophenyl) (4-(phenylethynyl)phenyl)methanone (DPEB), 4,4′-oxydianiline (4,4′-ODA)), 4-phenylethynylphthalic anhydride (4-PEPA) as the end-capping reagent. The chemical structure, thermal properties, solubility, melt flow behavior imide oligomers characterized...
This paper reviews a number of engineering technologies and workmanships for addressing the challenging issues concerning possible landslides in large-scale slope reinforcement projects China. It includes: (1) multi-point anchored piles with depth 64 m Jietai Temple rehabilitation project, (2) soil nailing strengthened by driven pipe grouting technique covering an area 530 × 100 (length height) Xiluodu hydropower (3) cantilever extending vertically from toe to stabilize 300 high at Xiaowan...
Abstract 3,3′,4,4′‐Diphenylthioether dianhydride (4,4′‐TDPA), 2,3,3′,4′‐diphenylthioether (3,4′‐TDPA), and 2,2′,3,3′‐diphenylthioether (3,3′‐TDPA) were synthesized from 3‐chlorophthalic anhydride 4‐chlorophthalic anhydride. A series of polyimides derived the isomeric diphenylthioether dianhydrides with several diamines prepared. The properties, such as solubility, thermal mechanical behavior, dynamic wide‐angle X‐ray diffraction, permeability to some gases, compared among polyimides. Both...
The acoustic emission (AE), ultrasonic velocity and stress-strain behaviors of brittle rocks containing natural fractures were simultaneously measured under uniaxial compression. An optimized sparse network transducers was used to monitor the crack-induced AE activities changes velocities in different directions. variation rock anisotropy co-characterized by wave localization hypocenters. microscale failure investigated analysis waveforms multiple characteristic parameters. A flurry AEs...
