“…These boundary conditions were chosen in accordance with the information given for ABS, an amorphous thermoplastic mix made up of a composition of 40-60% styrene, 5-30% butadiene, and 15-35% acrylonitrile. Various qualities can be attained depending on the combination [24]. The data in Table 1 were inputted into the design expert software and run to generate the sixteen (16) numbers of experimental runs for the study.…”

“…For samples that have experienced degradation, the mass gain is larger because shorter chains react with oxygen more quickly. Since volatile chemicals evolved after the reaction with oxygen, the reprocessed samples begin to lose mass more quickly [24,25]. However, all samples of the polymer mixes will remain stable up to about 350 o C. However, it was discovered that more than half of the polymer blend was lost when the material was heated to a temperature between 380 and 400 o C.…”

Combining two or more polymers as a blend is necessary rather than synthesizing new ones for the balance of polymer properties for end-use applications. This work introduces a sustainable polymer blend (matrix) for high-impact applications, as the accessibility and cost of production of these high-impact polymers keep souring. This was achieved by designing an experiment using design expert v10.0 to account for the number of experimental runs and optimise the polymer blend. Mechanical, dynamic mechanical, and temperature effects were considered on the blended polymer. Sixteen ( 16) experimental runs were generated with blend ratio as the independent variable and Impact Strength (IS) and Tensile Strength (TS) as the responses. The optimal blend ratio was obtained for wPP, PP and NR as 23, 30 and 47 % respectively. While, the optimum conditions for maximum impact and tensile strengths from the D.E was 241.62 J/m and 118.04 MPa respectively, with a desirability of 0.973. While the validated values obtained were 248.9 J/m; with errors of 2.93 % and 120.14 MPa; with an error of 1.75 % respectively. Thermogravimetry analysis revealed a single peak degradation for sp17, sp18, and sp19 (control samples) while multiple degradation peaks were observed for the blends. It was believed to be a result of different times for degradation of the individual components forming the polymer blend. Also, the T d onset started around 300 o C and the T d offset was around 500 o C for all tested samples. While, the Dynamic Mechanical Analysis (DMA) showed that there was an improvement in the T g and damping factor for sp5 (109 o C, 0.171) as compared to sp17 and sp18 (81.1 o C, 0.089 and 104.3 o C, 0.061), but no improvement was recorded for storage and loss moduli. SEM micrographs showed a good surface morphology for the blend with optimal mechanical and thermal properties. The blend can be utilized for engineering applications, including matrices for body armour, helmets, car bumper, etc.

“…It is important to note that chemically altering the material's surface may be essential for improving the material's compatibility with matrices. The surface chemical modi cation of natural bres seems to be the rst option to preserve its inherent nano bre qualities to boost compatibility with various matrices or to add new functions [30][31][32].…”

In this work, the effect of jute nanofibre on ter-blend of waste polypropylene (wPP), polystyrene (PS), and natural rubber (NR) nanocomposite was studied. The nanofibre was produced from jute fibre via a ball milling process after freezing with liquid nitrogen. The produced nanofibre was analyzed using Fourier Transform Infrared Spectroscopy (FTIR) and Dynamic Light Scattering (DLS). The ter-blend was modified with the nanofibre at different weight percentages (2–10 wt%) at 2wt% intervals. The modified polymer blends were characterized for mechanical, thermal, physical and morphological properties. FTIR revealed the removal of hemicellulose, lignin and other impurities from the jute fibre, due to the change in wave numbers observed. The DLS analysis showed that an average of 85.54 nm size distribution by the intensity and Polydispersity Index (PDI) of 0.353 was achieved. Also, the thermogravimetry analysis (TGA) showed that jute nanofibres proved to be thermally stable up to 282 oC. Polymer blends modified with 2 wt% nanofibres had the highest average impact and tensile strengths. While, the percentage water absorption (%WA), showed that sp10% absorbed the highest amount of water after 24 hrs. The weight losses of the modified blend at various temperatures were found to increase with the addition of nanofibre. The Scanning electron microscope (SEM) revealed cracks, voids and blend-separation as the amount of jute nanofibre was increased. While, Dynamic Mechanical Analysis (DMA) revealed that the Tg of the modified blend was improved, while the loss-factor improved greatly by 43%, but the storage and loss-moduli remained unchanged.
