Poly--lactic acid (PLLA) is an environmentally friendly and renewable polymer material with excellent prospects, but its low crystallization rate greatly limits its application. Through the amidation reaction between amino hyperbranched polymer (HBP N103) and carboxylated carbon nanotubes (CNTs), CNTs-N103 was obtained. The modification was confirmed by Fourier-transform infrared (FTIR) spectroscopy, X-ray electron spectroscopy (XPS) and thermogravimetric analysis (TGA).

- The manuscript discusses the modification of graphene oxide (GO) with hyper-branched polyester (HBP) and its effects on the mechanical and wear properties of acrylonitrile-butadiene-styrene (ABS) composites.
- The successful grafting of HBP onto GO was confirmed using various spectroscopy and microscopy techniques, with a calculated graft amount of 9.6 wt%.
- Results showed that HBP-m-GO enhanced the mechanical properties of ABS significantly, increasing tensile strength by 30%, while also improving wear performance by reducing friction and weight loss during tests compared to both pure ABS and ABS/GO composites.
