“…CaCO 3 is one of the most common fillers, inexpensive and widely used in plastics, rubber and polymer composites. The CaCO 3 particles are also applied to improve the mechanical property (Ma et al , 2022; Zhao et al , 2022a, 2022b), water-soluble property (Zhao et al , 2021; Wondu et al , 2021), thermal stability (Gbadeyan et al , 2022; Nekhamanurak et al , 2022), degradability (Wang et al , 2019; Pavon et al , 2022), application (Helanto et al , 2021; Nayunigari et al , 2014) and reduce the cost (Kong et al , 2021) of the biodegradable polymer materials. Moreover, generally, the price of PLA or PBAT is 15 times higher than that of CaCO 3 .…”

Purpose The purpose of this study is to improve the mechanical property and processing performance and reduce the cost of the polylacticacid/polybutyleneadipate-co-terephthalate(PLA/PBAT) composites, the calcium carbonate (CaCO3) and compatibilizer styrene-maleicanhydride copolymer (SMA-2025) were added to the PLA/PBAT system, and the effect of CaCO3 and SMA-2025 on the morphology, structure, mechanical property, thermal property, thermalstability and shape memory property of the CaCO3/PLA/PBAT composites were studied and discussed. Design/methodology/approach The CaCO3/PLA/PBAT shape memory composites were prepared via melt-blending and hot-pressing methods, and the effect of CaCO3 and SMA-2025 on the property of the composites was investigated via scanning electron microscope, universal testing instrument, Fourier transform infrared spectroscopy, differential scanning calorimetry, thermogravimetric analysis and DMA, respectively. Findings The interface property, mechanical property, thermal stability, shape memory recovery ratios and recovery stresses, and processing performance of the CaCO3/PLA/PBAT shape memory composites were significantly improved by adding of CaCO3 and SMA-2025. Moreover, the CaCO3/PLA/PBAT composites have good blowing film processing performance. Originality/value This study will provide a reference for the research, processing and application of the high-performance CaCO3/PLA/PBAT shape memory composites.
