Abstract
The mechanical and conductivity of magnetic polymer nanocomposite (MPNC) of nickel zinc (NiZn) ferrite nanoparticles incorporated with poly(lactic acid) (PLA) and liquid natural rubber (LNR) as compatibilizer is reported. The matrix was prepared from PLA and LNR in the ratio of 90 : 10. The MPNC of PLA/LNR/NiZn ferrite then was prepared via Thermo Haake internal mixer using melt-blending method from different filler loading from 1–5 wt% NiZn ferrite. The result of tensile tests showed that as the filler loading increases, the tensile strength also increases until an optimum value of filler loading was reached. Young’s modulus, tensile strength, and elongation at break have also increased. The study proves that NiZn ferrite is an excellent reinforcement filler in PLA/LNR matrix. The optimum thermal conductivity of PLA/LNR composites achieved with (4 wt% NiZn) due to the effective combination of NiZn-NiZn conductive networks. The scanning electron micrograph (SEM) reveal that the aspect ratio and filler orientation in the PLA/LNR matrix also strongly promoted interfacial adhesion between the filler and the matrix to control its properties.
Highlights
Poly(lactic acid) (PLA) has received great attention due to its biodegradable, renewability, and comparable properties with petroleum-based polymers
The optimum tensile strength is obtained at 4 wt%, with an increasing of 20% compared to the nonfiller poly(lactic acid) (PLA)/liquid natural rubber (LNR) blends
Young’s modulus of higher filler loading decreased due to the increase of aggregation of nickel zinc (NiZn) ferrites in PLA/LNR matrix, and this can be revealed in scanning electron micrograph (SEM) analysis later on
Summary
Poly(lactic acid) (PLA) has received great attention due to its biodegradable, renewability, and comparable properties with petroleum-based polymers. PLA is a typical biodegradable polyester obtained by synthesis of lactic acid (or lactide), which can be produced from renewable resources such as corn or sugarcane [1]. It is a sustainable alternative to petrochemical-derived products. A great deal of research work on plastic materials has been dedicated to the application of biodegradable materials. It is gaining popularity as it has been accepted in many application areas such as food packaging, bags and sacks, loose-fill packaging agricultural film, and some specialty application [3]
