Dataset of various characterizations for novel bio-based plastic poly(benzoxazole-co-benzimidazole) with ultra-low dielectric constant

Abstract

The data presented in this specified data article comprise of various characterization such as: structural, thermal, elemental etc. to understand the novel structure and specific properties of the bio-based plastic as described in the main research article “High-performance poly (benzoxazole/benzimidazole)bio-based plastics with ultra-low dielectric constant from 3-amino-4-hydroxybenzoic acid” [1]. The data of 1 H NMR spectra of two monomers and their HCl salt formation required for polymerization, FT-IR spectra of polymer formation before and after thermal ring-closing and additionally supported by the thermogravimetric plots where mass loss due to water is observed around 400 °C (thermal ring closing temperature). Solvent plays effective role to change dielectric properties significantly, complete removal of the remaining solvents was confirmed by X-ray photoelectron spectroscopy (XPS) technique. Wide-angle XRD dataset was presented here to make an idea about degree of crystallinity of the prepared polymers.

Advanced Polymers from Simple Benzoxazines and Phenols by Ring-Opening Addition Reactions

“…Besides, the CN stretching vibration band of benzoxazole at ca. 1642 cm –1 is detectable . Moreover, in Figure b,c, the presence of broad hydroxyl bands confirms the successful ring-opening polymerization of benzoxazine.…”

“…1642 cm −1 is detectable. 63 Moreover, in Figure 4b,c, the presence of broad hydroxyl bands confirms the successful ring-opening polymerization of benzoxazine. It is also deduced from the shape of the hydroxyl bands that the hydroxyl groups have more hydrogen-bonding interactions before the second thermal treatment.…”

In situ synthesis of star copolymers consisting of a polyhedral oligomeric silsesquioxane core and poly(2,5‐benzimidazole) arms for high‐temperature proton exchange membrane fuel cells

“…S1, characteristic peaks were observed for the Si-O cage structure at 1092 cm -1 and for the telescopic vibration of the benzene ring skeleton at 1631 cm -1 from DABA [26], confirming the presence of the POSS and DABA components in the composite materials. Meanwhile, the [35], while the peak at 2.01 ppm attributed to the secondary ammonia [33,36] and 0.86 ppm to the hydroxyl. At the same time, the peak at 3.21 ppm corresponding to the proton on the epoxy group [36,37] does not appear in the spectrum of POSS-DABA.…”
