Effect of plasticizer dibutyl phthalate on the thermal
This paper aims to investigate the effects of plasticizer dibutyl phthalate (DBP) on the thermal decomposition of nitrocellulose (NC) by using a series of analytical apparatuses. In the present study, the detailed structures of pure NC (NC-P) and NC with DBP (NC-D) were revealed by scanning electron microscope. It was found that the fibers in NC-D are more closely aligned than those in NC-P
Dibutyl phthalate contamination accelerates the uptake and
Abstract Dibutyl phthalate (DBP) is widely used as plasticizer and has been detected in the environment, posing a threat to animal health. However, the effects of DBP on agricultural microbiomes are not known.

Plasticizer effect of dibutyl phthalate on the morphology and
The PVDF/DBP blend fibers were prepared by melt spinning and subsequent annealing. The crystalline structure and thermal properties of the blend fibers were analyzed in terms of the long-period lamellar spacing, crystal structure, and degree of crystallinity with X-ray diffraction, differential scanning calorimetry, and small-angle X-ray scattering.
- Does plasticizer dibutyl phthalate affect thermal decomposition of nitrocellulose?
- This paper aims to investigate the effects of plasticizer dibutyl phthalate (DBP) on the thermal decomposition of nitrocellulose (NC) by using a series of analytical apparatuses. In the present study, the detailed structures of pure NC (NC-P) and NC with DBP (NC-D) were revealed by scanning electron microscope.
- How does plasticizer DBP affect the microscopic structure and thermal decomposition mechanism?
- The effects of DBP on the microscopic structure, kinetic characteristics, and thermal decomposition mechanism of NC were investigated using a range of apparatus. The main findings can be summarized as follows: 1. Plasticizer DBP makes NC fibers present an adhesion state. The distance between fibers in NC-D is much lower than that in NC-P.
- Does plasticizer entrap DBP and intertwined polymer complex?
- In addition, the broad peak is shifted to higher Bragg angle with addition of plasticizer. It is indicative of the entrapment of plasticizer via formation of the coordination bonding between DBP and intertwined polymer complex. XRD patterns of SPE1 and SPE7
- What happens when DBP is added to PVC-Li 2 b 4 O 7?
- Upon addition of DBP, there is the formation of a new peak which assigned as C = O stretching mode at 1,728 cm −1 as shown in Fig. 2b, c. Figure 2b, c indicate that the peak at 1,734 cm −1 for DBP is shifted to 1,728 cm −1 for SPE4 and SPE7, respectively. This is evidence of complexation between PVC–Li 2 B 4 O 7 and DBP.
- What is the interaction between Li 2 b 4 O 7 and DBP?
- The interaction between the PVC, Li 2 B 4 O 7, and DBP were studied by Fourier transform infrared. The shifting, broadening, and splitting of transmission peaks were the evidences of complexation. The highest ionic conductivity polymer electrolyte of 2.83 × 10 −6 S/cm was achieved at ambient temperature upon addition of 30 wt.% of DBP.
- How does a high mass fraction of DBP affect ionic conductivity?
- High mass fraction of DBP would weaken the interactions within the polymer chains and reduces the solvation of Li cations by polymer matrix. It initializes the decoupling of ions, enhances the dynamic free volume of the polymer system and thereby increases the ionic conductivity.
