Purpose This work aims to develop a new kind of semicrystalline polymer filament and optimize its printing parameters in the fused deposition modeling process. The purpose this also includes producing FDM parts with good ductility. Design/methodology/approach A filaments composed long-chain polyamide (PA)1012 was prepared by controlling screw speed pulling carefully. optimal for PA1012 were explored through investigating dimensional accuracy bonding strength parts. Furthermore, mechanical...
Abstract Currently, material extrusion‐based additive manufacturing (MEAM) technique, also known as fused filament fabrication (FFF) technique has been widely used to prepare customized porous scaffolds for bone tissue engineering. However, often lack desirable osteogenic properties due the poor hydrophilicity of polymer materials FFF technique. In this work, biocompatible suitable are prepared by blending polycaprolactone (PCL), polylactic acid (PLA), and tricalcium phosphate (TCP) at...
We revealed the mechanism of cellulose benzoylation in an ionic liquid by using Hammett parameters, and found that exhibited a high C-6 regioselectivity.
One key issue restricting semi-crystalline polymers to be widely applied in powder bed fusion (PBF) of is lack good processability, especially a wide sintering window. In this work, thermal treatment method with mixed dispersant system (TTMS) was developed modify common isotactic polypropylene (PP) adapt for PBF. Both window (SW) and particle morphology the PP were improved by TTMS process. The SW expanded from 15 °C raw 51 TTMS-PP powder, since process facilitated formation α crystal larger...
Abstract Summary: Poly(ethylene 2,6‐naphthalate) (PEN) can crystallize either from the glassy state or melt state. When crystallized state, sample was quenched in liquid nitrogen and then annealed at certain crystallization temperatures. cooled to a preset temperature for time. The crystal modifications, morphologies melting behaviors of PEN were investigated by means wide‐angle X‐ray diffraction (WAXD), polarized optical microscopy (POM), small‐angle light scattering (SALS) differential...
The crystallization behaviors and morphology of poly(ethylene 2,6-naphthalate) (PEN) in the presence liquid crystalline polymer (LCP) Vectra RD501 have been studied by differential scanning calorimetry (DSC), polarized optical microscopy (POM), atomic force (AFM), wide-angle X-ray diffraction (WAXD). It was found that LCP PEN/LCP blends accelerates rate PEN at both higher low temperatures, which indicates acts as nucleating agent nucleation promoter for crystallization. effectively improved...
Abstract The crystallization and morphology of poly(ethylene‐2,6‐naphthalene dicarboxylate) (PEN) containing, as nucleating agents, a sodium salt copolymer ethylene acrylic acid or methacrylic acid, were investigated with differential scanning calorimetry, polarized optical microscopy, small‐angle light scattering. agents accelerated the rate at high temperatures by decreasing surface free energy barrier hindering nucleation. Meanwhile, flexible chains could also improve mobility PEN...
The influences of additives, Ceraflour 991® (low molar mass polyethylene), 993® polyamide), and poly (1,4-butylene sebacate), on the crystallization poly(ethylene 2,6-naphthalate) (PEN) were investigated by means differential scanning calorimetry, electron microscopy, polarized optical microscopy. It was revealed that these additives could substantially accelerate PEN at low temperature due to an improvement molecular motion PEN. They can be attributed a kind nucleating promoter. also...
Abstract The influence of nucleating agents (AClyn ® , Surlyn and sodium benzoate (SB)) alone together with promoter (Ceraflour 993 Ceraflour 991 poly(1,4‐butylene sebacate)) on the crystallization morphology poly(ethylene 2,6‐naphthalene dicarboxylate) (PEN) was investigated by means differential scanning calorimeter, polarized optical microscopy small angle light scattering. It revealed that AClyn, SB effectively accelerate nucleation PEN increasing ratio agent up to 1 wt.‐%. A combination...
Abstract The influence of additives on the crystal modification and melting behavior poly(ethylene‐2,6‐naphthalene dicarboxylate) (PEN) was investigated with wide‐angle X‐ray diffraction differential scanning calorimetry (DSC). addition a nucleating promoter, Ceraflour 993, had no effect PEN crystallized under all chosen experimental conditions. However, agent, sodium benzoate (SB), did affect when PEN/SB at higher temperature, but not lower temperature. A mixture α β modifications obtained,...
Objective. To study the clinical efficacy of integrated traditional Chinese medicine (TCM) and Western (WM) in treating endometrial cancer influence on ultrasound, magnetic resonance imaging (MRI), tumor markers, human epididymis protein 4 (HE4) carbohydrate antigen 125 (CA125). Method. A total 152 cases patients with carcinoma were randomly divided into two groups: TCM + WM group group. The was treated megestrol acetate tablets, Radix Astragali injection basis control levels inflammatory...
Bisphenol A poly(carbonate) (PC) pellets used for production of 5 gallon drink water bottles were reprocessed in a twin-screw extruder three processing cycles which simulated to those PC bottle conditions. The characterized by its mechanical, rheological, thermal, and optical properties. It was found that the mechanical properties samples are slightly decreased after reprocessed. Whereas no further change observed rheological thermal molecule weight second reprocessing cycles. Moreover, melt...
