Ller delivers positive aspects to improve the thermal stability properties of kenaf/HDPE composites. three.two.two. Differential Scanning Calorimetry (DSC) The DSC thermograms, melting point (Tm ) and glass transition temperature (Tg ) Exendin-4 site values on the kenaf/HDPE composites with and without having AgNPs are shown in Figure 9 and Table 2. DSC study on supplies is important because it can analyze the properties of composite supplies [43]. From Figure 9, the glass transition temperatures, Tm (midpoint values), of kenaf/HDPE composites with AgNPs are greater than these of kenaf/HDPE composites with out AgNPs. The results MCC950 Biological Activity indicate that the addition of AgNPs tends to raise the prohibition on the movement on the polymer matrix chain. The Tm (onset value) with the kenaf/HDPE composites also drastically increased with escalating the AgNPs contents from 2 wt to 10 wt , and it indicates that the addition of AgNPs into Kenaf/HDPE composites is more stable than without having AgNP content material. Kenaf/HDPE composites with more AgNPs have a Tm (onset value) slightly greater than those with significantly less concentration of AgNPs, and consequently the thermal properties of kenaf/HDPE composites have also been impacted by AgNPs. The Tm (onset worth) for kenaf/HDPE with 10 wt is 128.53 C when in comparison to those with a reduced concentration of AgNPs. The Tm (onset worth) increases as a consequence of AgNP content material, which could make the structure amongst kenaf and HDPE modify and enhance the structure by the content of AgNPs. Combining AgNPs into compositesPolymers 2021, 13,9 ofenhanced the thermal stability and was similarly reported by yet another author [446]. Variations within the Tm (midpoint worth) could possibly also adversely identify the compatibility with the samples. From Table 2, Tm (midpoint worth) levels of kenaf/HDPE composites with 0 wt of AgNPs is lesser (129.97 C) than kenaf/HDPE composites with 10 wt of AgNPs (133.83 C). The intermolecular forces between kenaf/HDPE composites matrixes are resulting from AgNPs in mixes, which can strengthen the interfacial bond amongst mixing components [37,45]. The mixture of kenaf/HDPE composites with AgNPs offered Polymers 2021, 13, x FOR PEER Review the advantages to generate high-quality multifunctional components and it is also appropriate for different manufacturing applications.9 ofFigure 9.
