2021年9月1日 · The structure of the PBAT/VL composite was characterized from gel content measurements, SEM, TEM, XRD, DSC, and rheological behavior data. Compared with PBAT, the tensile strength, Young's modulus, and biodegradation efficiency of the PBAT/VL composite with 30 wt% of VL increased by 200%, 151%, and 96%, respectively.

Carbon Black addition caused a significant increase on tensile strength and elongation of blend. It can be seen in Figure 2, the XRD pattern of PBAT/PLA blend showed a prominent 2 peak at...

2021年5月1日 · X-ray diffraction (XRD) of PBAT films The PBAT films before and after degradation were tested using XRD (D/max 2200 PC, Rigaku, Japan), and the power source was a CuKα target with a scanning range of 10°–50°.

2021年10月25日 · XRD indicated that the intensities of PBAT diffraction peaks slightly increased with time as compared to blank PBAT. It showed that the amorphous phase of PBAT decreases due to degradation by enzymes.

2017年12月1日 · The degree of crystallinity of nanocrystals before and after chemical treatment was analyzed by X-ray diffraction (XRD) using a Philips XPert X-ray diffractometer with Cu-Kα(λ = 1.54060 Å), 40 kV voltage and 40 mA current. The sample was scanned from 5°≤ 2θ≤ 50°.

2014年4月1日 · XRD结果表明：合成的不同n（DMT）∶n（AA）的PBAT具有相同的结晶结构，且与PBT均聚物的结晶结构相同；DSC结果表 明：结晶温度、结晶度和熔融温度随着BT单元含量的增加而提高，当BT含量达到80％时，出现明显的双重熔融峰；TGA结

The addition of 3 % in wt of TiO2 in PBAT/PLA blend leads to obtaining of new material with higher melting enthalpy, and melting temperature than original blend.

2023年5月23日 · The XRD results demonstrated that due to low crystallinity, the strengths of PBAT diffraction peaks became frail after degradation and the intensity of the (010) and (100) peaks increased, whereas the (111) peaks decreased significantly that indicating the possible degradation of the amorphous phase of PBAT, however, crystalline phase remained ...

2023年3月6日 · The influence of PBAT on the thermal properties of PCL was investigated by thermogravimetric (TG) measurement, differential scanning calorimetry (DSC), polarized optical microscopy (POM), and X-ray diffraction (XRD) methods. The results of TGA and DSC showed that with the increase of PBAT, thermal properties of the blends were improved.

2020年3月11日 · Biodegradable blends of poly(butylene adipate-co-terephthalate) (PBAT) and stereocomplex polylactide (sc-PLA) were prepared herein via a melt blending method at various sc-PLA loadings. Wide-angle X-ray diffraction and differential scanning calorimetry results verified that complete stereocomplex polylactide crysta
