X-ray Diffraction (XRD) Measurements Figure 2 shows the XRD patterns of raw PVC, Al 2 O 3, and prepared Al 2 O 3 /PVC catalysts. The XRD pattern of PVC powder displays relatively...

In the present study, the amorphous structure of varying weight fractions PVAc\PVC were determined via XRD patterns and to correlate their internal structure with other physical and chemical ...

In this study, we prepared Polyvinyl chloride (PVC)/Nitrocellulose (NC) polymer blend by the solution casting technique. The structural properties and decreased interplanar spacing and...

2024年3月24日 · 聚苯乙烯是一种透明硬质塑料，用于制作各种塑料制品。其xrd特征峰为2θ = 24.2°和29.4°，这些峰代表了聚苯乙烯晶体的(100)和(110)平面的衍射峰。相邻平面间距较远，显示出较明显的宽峰。 聚氯乙烯（pvc）

The X-ray diffraction patterns of pure PVC, and its composite samples are shown in Figs. 3(a–g), respectively. It is evident from Fig.3 (a) that PVC exhibits an amorphous phase. The XRD spectrum of BT (Fig. 3g) shows 4 peaks in the 10°–50° range. These peaks appear in the XRD patterns of all composite samples.

XRD and FESEM characterization techniques were used to study the properties of the PVC-based proton-conducting polymer electrolytes. XRD studies show that amorphous PVC becomes largely amorphous upon adding NH4CF3SO3. Largely amorphous is also obtained upon adding EC and Bu3MeNTf2N to PVC-NH4CF3SO3. XRD studies of the salted samples showed

2021年9月1日 · PVC films containing 40% of ECLO exhibited efficient mechanical properties. Synthesized PVC films were analyzed by SEM, XRD, DTG and TGA, DSC, and FTIR. PVC ECLO 40 films were exhibited better plasticizing effect and thermal stability. Biobased plasticizers for polymers is a necessity to replace conventional phthalates based plasticizers.

2022年9月11日 · The obtained XRD patterns for PVC, Fe 2 O 3-PVC, and 5% CDF-PVC are depicted in Figure 3. The XRD pattern of pure PVC confirms its amorphous nature with no prominent sharp peak, but a broad peak in the region of 2θ in the range of 10° to 25° appears as previously reported in the literature.

2019年9月1日 · In the present study, the amorphous structure of varying weight fractions PVAc\PVC were determined via XRD patterns and to correlate their internal structure with other physical and chemical properties [19].

1999年3月1日 · The crystal structure of poly(vinyl chloride) (PVC) was first reported by Natta and Corradini[1], who showed that it possessed an orthorhombic unit cell with dimensions a=1.06 nm, b=0.54 nm and c=0.51 nm. They also indexed the five most intense peaks observed in the X-ray diffraction pattern.
