Poly(Lactic Acid) (PLA)/Acrylonitrile Butadiene Styrene (ABS) with Graphene Nanoplatelet (GNP) Nanocomposites

Abstract

A melt blending of poly(lactic acid) (PLA)/acrylonitrile-butadiene-styrene (ABS) with 30:70 PLA:ABS was prepared by a twin screw extruder with a die of 25 mm width and 0.5 mm thickness with various loadings of graphene (0-1.0 wt.%). The PLA/ABS blends were evaluated for mechanical, morphology, thermal properties and interaction of the components in the blend system. Results show the incorporation of graphene nanoplatelet (GNP) improved the tensile and modulus properties. Nevertheless, it was observed that at higher GNP loadings, i.e., 0.6-1.0 wt.%, both tensile and modulus properties showed a decreasing trend. It was also found that the thermal stability for the blend slightly improved when graphene presence in the blend.

Influence of dammar gum application on the mechanical properties of pineapple leaf fiber reinforced tapioca biopolymer composites

“…Once again, this can be attributed to the plasticizer effect, whereby an excessive amount of plasticizer can modify the structure of the TBP matrix and reduce its ability to support the PALF fibers mechanically. This rupture can lead to a weakening of the interfacial adhesion between the fibers and the matrix, causing a reduction in tensile strength 25,51,52 . In addition, Figure 3 demonstrates that impact strength follows a similar pattern to tensile and flexural properties.…”

Pengaruh Penambahan Magnesium Terhadap Sifat Mekanik, Mikrostruktur Dan Electrochemical Impedance Spectroscopy Polimer Pla/Abs Untuk Material Implan Bioabsorbabel

“…Komposisi PLA80/ABS20/Mg5 menghasilkan kekuatan tarik maksimum terendah yaitu 4,03 MPa dan Young Modulus sebesar 1130 MPa serta menghasilkan elongasi cukup tinggi sebesar 2,38% dengan mulur sampai dengan putus sepanjang 7,3 mm (Gambar 1(c) dan Tabel 4). Komposisi ini memiliki tingkat kekakuan paling tinggi dengan keuletan yang cukup baik karena kandungan PLA cukup besar yaitu 80 %berat [16]. Dari Gambar 1(a)-1(c) dan Tabel 4, dapat disimpulkan bahwa semakin banyak variasi Mg yang ditambahkan maka akan meningkatkan kekuatan tarik maksimum komposisi PLA/ABS/Mg.…”

Statistical Study on the Interaction Factors of Polypropylene-Graft-Maleic Anhydride (PP-g-MA) with Graphene Nanoplatelet (GNP) at Various Poly(Lactic Acid)/Polypropylene (PLA/PP) Blends Ratio

“…Apart from that, incorporation of nanofiller into the blends also serves a significant impact on the final properties of nanocomposites, such as mechanical, thermal, morphology, and interfacial properties [20][21][22]. In recent years, many papers reported on PLA/PP blends reinforced with clay [23][24], multi-walled carbon nanotubes [25], and sepiolite [26].…”
