FT-IR methodology (transmission and UATR) to quantify automotive systems

Abstract

ObstractWhen using Fourier transform infrared spectroscopy (FT-IR) under the qualitative aspect for characterization of polymer blends, often a simple identification of each one of the existing polymers in the blend does not justify the material failure since different amounts of each component may result in different mechanical properties, which should be a possible cause for of material failure when applied to an automotive part. Thus, seeking for a better justification in the understanding of material failure analysis, a new quantitative FT-IR methodology was developed in the mid-infrared region (MIR), using the transmission techniques and universal attenuated reflectance for the determination of Acrylonitrile Butadiene Styrene (ABS) and polycarbonate (PC). Transmission mode was more suitable. The relative band (A 831 /A 2237 ) was chosen for the preparation of the calibration curve that showed a 0.99% error methodology, which is within the FT-IR spectrometer accuracy limit (≤ 2%); therefore, it is accurate for the analysis of the system.

Tribological response of polycarbonate and acrylonitrile butadiene styrene blends containing fixed amounts of Kevlar fibre and molybdenum disulphide with varying quantities of betel nut powder

“…33 PC/ABS composite without any additives have peaks mainly at 993 cm −1 , 1216 cm −1 , 1537 cm −1 , 1679 cm −1 , 2349 cm −1 and 3064 cm −1 respectively, which represents C=C stretch in ABS, C-O-C deformation in both PC and ABS, stretching of C-C bond with the aromatic ring, carbonyl stretch in PC, C≡N deformation and aromatic stretch for both PC as well as ABS. 34 The PC/ABS/Kevlar/MoS 2 composite have the main peak at 731 cm −1 for MO-O coordination of MoS 2 along with N-H bending of Kevlar which overlaps with the other peaks of PC/ABS. The N-H stretching peak at 3256 cm −1 and 3084 cm −1 of Kevlar also overlaps with the aromatic C-H stretch of PC/ABS.…”

Review on the photonic techniques suitable for automatic monitoring of the composition of multi-materials wastes in view of their posterior recycling

“…According to the state-of-the-art of the technique, spectroscopy in the MIR region has been used for the characterization of a great diversity of plastics, including those commonly used in the motor vehicle industry such as those filled with carbon black and/or reinforced with carbon or glass fibres, hereafter referred to as black plastics ( Chércoles Asensio et al, 2009 ; Ferreira et al, 2018 ; Jung et al, 2018 ; Kassouf et al, 2014 ; Rozenstein et al, 2017 ; Stark and Matuana, 2007 ).…”

Waste acrylonitrile butadiene styrene (ABS) incorporated with polyvinylpyrrolidone (PVP) for potential water filtration membrane

“…Acrylonitrile butadiene styrene (ABS) is a thermoplastic polymer consisting of 70-80% styrene-acrylonitrile copolymer (SAN) and 20-30% polybutadiene rubber. 1,2 Owing to its excellent heat resistance, glossy surfaces, high hardness, and easy processability, 3 ABS has been widely used as housing materials for automotive systems, air conditioners, computers, and electronic appliances. [3][4][5][6][7] Rapid technology development requires design freedom for customized parts; therefore, 3D printing has become popular for polymer fabrication in many elds.…”
