摘要

In the current work, Bismuth Titanate (BTO)-modified Acrylonitrile–Butadiene–Styrene (ABS) composite films were produced by using the solvent blending method and characterized for the first time under quasi-static and dynamic loading conditions by using Nanoindentation techniques. A static load of 1000 µN was applied during Nanoindentation, and it was noticed that the nanomechanical properties of ABS were significantly improved with the addition of BTO. When compared to neat ABS, the elastic modulus and hardness were increased approximately by 109% and 57%, respectively, upon adding 5 wt.% BTO into ABS. Load–displacement curves indicated that the maximum depth was decreased from 484 nm for pure ABS to 280 nm for 5 wt.% ABS/BTO; while the final depth was reduced from 279 to 197 nm, respectively. This reduction signified that, in comparison with pure ABS, the ABS/BTO composites were hard to indent, and their elasticity was improved. Dynamic Mechanical Analysis (DMA) showed that across the frequencies, the storage modulus was improved by 80-100% for 5 wt.% ABS/BTO composites, equivalent to pristine ABS. The combined outcomes demonstrated that BTO acted as an efficient reinforcement for improving the overall mechanical behavior of the composite, making it a promising candidate for electronics casings, vibration-resistant enclosures, and structural applications for mechanical stability.
