The goal of this research is to investigate the thermal, chemical, and tensile properties of chemical modification of sugarcane bagasse (SCB)-filled polypropylene (PP) and recycled acrylonitrile butadiene rubber (NBRr). The composites with different SCB loading (5, 15, and 30 per hundred resin) were prepared using a heated two-roll mill at temperature of 180°C.Thermal and the tensile properties of the modified SCB composite have shown improvement. The silane-treated composites have higher thermal stability compared to treated NaOH. The degradation temperature at 70% weight ( T 70%) of NaOH and silane composite increase by 6% and 15%, respectively. Meanwhile, the tensile strength and Young’s modulus for the both treatment showed an improvement of 20% and 25% for NaOH and 30% and 32% for silane compared to untreated composites, respectively. The chemical properties were investigated using Fourier transform infrared analysis. The modification SCB fiber has improved the adhesion and interfacial bonding between SCB fiber and PP/NBRr matrices.

Cure characteristics and crosslink density of virgin acrylonitrile butadiene rubber/recycled acrylonitrile butadiene rubber (vNBR/rNBR) blends were studied. Three different size ranges of rNBR particles, i.e., 150 - 350 μm, 2.0-15.0 mm, and 5-10 cm were used in this study. The vNBR/rNBR blends with blend ratios of 95/5, 85/15, 75/25, 65/35, and 50/50 were prepared using a two roll-mill at room temperature. The characterization results of the blends show that scorch time, t2, of the vNBR/rNBR blends decreased with increased rNBR content as well as decreasing sizes of rNBR particles while cure time, t90of the vNBR/rNBR blends increase with increased rNBR content as well as increasing sizes of rNBR particles. Among all blend ratios, the vNBR/rNBR blends with smallest size of rNBR particles exhibit lowest minimum torque (ML) compared with the bigger particle sizes of it in vNBR/rNBR blends which resulted in more efficient processing. The maximum torque (MH) of all vNBR/rNBR blends shows the inclining trend with increased rNBR. The cross-linking density of vNBR/rNBR blends also show an increasing trend with increasing rNBR content.

Polypropylene (PP)/ recycled acrylonitrile butadiene rubber (NBRr)/ banana skin powder (BSP) composites were studied. Different BSP filer loading (5, 10, 15,20,25,30 wt. %) were prepared by using heated two roll mill at 180 °C. Then, the composites were tested for functional group using FTIR model Perkin Elmer Series 2. Field Emission Scanning Electron Microscope (VPFESEM) model Zeiss SUPRA 35VP also were using for morphological study. The effect of 3-aminopropyltrimethoxysilane (APS) as coupling agent were evaluated.The FTIR test shows different bands around 3200-3500 and 1740 cm-1 which represent the stretching of OH and C=O groups respectively. As for BSP which composed mostly of cellulose, hemicelluloses and lignin, the cellulose backbone C-OH is represent by the peaks of 1050 and 1048 cm-1 respectively. The γ-APS intense band around 1167 cm-1 and 1098 cm-1 in treated composite was assigned to the stretching of the-Si-O-Cellulose and –Si-O-Si-bond respectively. The large band around 1050 cm-1 found on BSP filler was attribute to the –Si-OH group which later this band will disappear after the surface modification. This evidenced that bonding between γ-APS treated BSP with PP/NBRr matrices. Morphological study supported this finding which BSP filler treated with γ-APS has improved the adhesion between BSP filler and PP/NBRr matrices.
