ThermogravimétrieIndex. décimale : 668.9 Polymères Résumé : The poly(acrylic acid)/poly(ethylene oxide) (PAA/PEO) blend nanofibers at 100/0, 80/20, 50/50, 20/80 and 0/100 weight ratios were obtained via electrospinning process. Intermolecular interactions, miscibility and compatibility of polymer blends were studied by Fourier transform infrared (FT-IR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and UV-visible spectrophotometer. The results suggest that intermolecular interactions have occurred between pure PAA and PEO in PAA/PEO blend. These interactions made PAA/PEO blend miscible at above-mentioned weight ratios. Additionally, the morphology and the fibers diameter were investigated using scanning electron microscope (SEM) analysis, which indicated beadless fibers with diameter range of about 120 to 300 nm. It was observed that the homogenous nanofibers with the smaller diameter were obtained in PAA/PEO blend with PAA dominant content. Finally, SEM results suggest that the formation of pure PAA nanofibers with concentration of 5.0 wt.% would not occur. Whereas, in the same concentration, pure PEO and PAA/PEO blend nanofibers with no bead defects were obtained. However, in higher pure PAA concentrations electrospun fibers were formed.

TétrahydrofuraneLe tétrahydrofurane (anciennement tétrahydrofuranne) ou 1,4-époxybutane ou oxolane ou oxacyclopentane ou encore oxyde de tétraméthylène, appelé souvent plus simplement THF, est un composé organique hétérocyclique. C'est un des éthers les plus polaires et il est utilisé en synthèse organique comme solvant de polarité moyenne. Il a une température d'ébullition plus grande que la plupart des éthers (Teb = 66 °C). Il est narcotique et toxique (VME 150 mg·m-3). On peut l'obtenir par déshydratation du butan-1,4-diol. Il est difficile de le conserver sec car il est relativement miscible à l'eau.
ThermoplastiquesUne matière thermoplastique désigne une matière qui se ramollit (parfois on observe une fusion franche) d'une façon répétée lorsqu'elle est chauffée au-dessus d'une certaine température, mais qui, au-dessous, redevient dure. Une telle matière conservera donc toujours de manière réversible sa thermoplasticité initiale. Cette qualité rend le matériau thermoplastique potentiellement recyclable (après broyage). Cela implique que la matière ramollie ne soit pas thermiquement dégradée et que les contraintes mécaniques de cisaillement introduites par un procédé de mise en forme ne modifient pas la structure moléculaire.Index. décimale : 677.4 Textiles artificiels Résumé : The thermoplastic polyurethane (TPU) micro-nanofibers were prepared successfully by electrospinning with N,Ndimethylformamide (DMF) and tetra-hydrofuran (THF) as solvent. The conventional receiving plate was replaced by a metal woven mesh, and TPU fibrous membranes having cross structure were prepared. Here, the micromorphology of the TPU micro/nanofibers and the macrography of the membrane surface were characterized by SEM and optical microscopy, respectively. In addition, the pore diameter distribution of the TPU firous membrane was tested. Note de contenu : - Experimental materials

Son -- AbsorptionIndex. décimale : 677.4 Textiles artificiels Résumé : In order to solve the problem of noise pollution, polyurethane (PU) nanofibrous membranes with different structures were prepared by electrospinning. The influence of layer number, single-layer basis weight arrangement and the concentration of MnO2 on the sound absorption performance was investigated. The results show that the sound absorption coefficient of the PU laminated nanofibrous membranes enhances initially and then declines with the increase of the layer numbers, reaching the maximum when the layer number is 8. The overall sound absorption performance of the PU nanofibrous membranes with increasing single-layer basis weight arrangement is better than that of the membranes with decreasing single-layer basis weight arrangement. When the concentration of Mn02 is 2 wt.%, the sound absorption coefficient of the MnO2/PU composite membrane achieves its peak value due to the fine fiber diameter and high porosity.
