“…It was obvious that the addition of OPB into the pure PVA composite has superbly improved the ability of composite to elongate, which was about 7-9 mm because OPB has strong ability to enhance the ductility of composites. Overall, the OPB/MWCNTs containing PVA hydrogels did not show high elongation break, indicating that the structure possessed high rigidity [50]. For tensile strength, the addition of 4 wt % MWCNTs has greatly improved the tensile strength of PVA hydrogel from 0.2 to 2.2 MPa.…”

Polyvinyl alcohol (PVA) hydrogel are still restricted for some applications because their lower mechanical strength and thermal stability. The PVA-based composites are drawing attention for the removal of heavy metals based on their specific functionality in adsorption process. The main objective of this work is to synthesize oil palm bio-waste (OPB)/multiwalled carbon nanotubes (MWCNTs) reinforced PVA hydrogels in the presence of N,N′-methylenebisacrylamide (NMBA) as a crosslinking agent and ammonium persulfate (APS) as an initiator via simple in-situ polymerization technique. The as-prepared reinforced nanocomposites were characterized by FESEM, BET surface area, differential scanning calorimetry (DSC), TGA and FTIR analysis. The possible influence of OPB and MWCNTs on the tensile strength, elongation at break and elastic modulus of the samples were investigated. It was found that reinforced nanocomposites exhibited enhanced mechanical properties as compared to non-reinforced material. The evaluation of reinforced nanocomposites was tested by the removal of Pb(II) aqueous solutions in a batch adsorption system. The pseudo-second-order kinetic model was used to illustrate the adsorption kinetic results and Langmuir isotherm was more suitable to fit the equilibrium results providing maximum adsorption capacities. The evaluation of thermodynamic parameters describes the spontaneous, endothermic and chemisorption adsorption process while activation energy reveals the physical adsorption mechanism. Therefore, the coordination effects among OPB, MWCNTs and PVA polymer hydrogels can produce a promising adsorbent material for wastewater treatment applications.

“…High stiffness nanocellulose is able to provide enhanced performance and stability to the hydrogel, even in low portions due to the high number of hydrogen bonds and entanglement of fibrils [77]. The insertion of 2 wt% of OPEFB gave a higher stiffness of specimens [78]. The insertion of nanocellulose enhanced the modulus and compression strength due to the good dispersion of nanocellulose in the hydrogel, and hence more effective crosslinking density and interfacial adhesion [77].…”

Oil palm empty fruit bunch (OPEFB) is considered the cheapest natural fiber with good properties and exists abundantly in Malaysia. It has great potential as an alternative main raw material to substitute woody plants. On the other hand, the well-known polymeric hydrogel has gathered a lot of interest due to its three-dimensional (3D) cross-linked network with high porosity. However, some issues regarding its performance like poor interfacial connectivity and mechanical strength have been raised, hence nanocellulose has been introduced. In this review, the plantation of oil palm in Malaysia is discussed to show the potential of OPEFB as a nanocellulose material in hydrogel production. Nanocellulose can be categorized into three nano-structured celluloses, which differ in the processing method. The most popular nanocellulose hydrogel processing methods are included in this review. The 3D printing method is taking the lead in current hydrogel production due to its high complexity and the need for hygiene products. Some of the latest advanced applications are discussed to show the high commercialization potential of nanocellulose hydrogel products. The authors also considered the challenges and future direction of nanocellulose hydrogel. OPEFB has met the requirements of the marketplace and product value chains as nanocellulose raw materials in hydrogel applications.

“…Increase nanocellulose in the matrix make the tensile strength decreased, it cause the possible aggregation of nanocellulose in the polymer matrix and also nanocellulose was not disperse homogeneously in the polymer matrix [14]. Increase in tensile strength is due to crystalline content of nanocellulose [15].…”

“…But for the film composites PVA filled with nanocellulose fron OPF some increase and some decrease. The decreased of elongation at break of PVA composite films could be attributed to the presence of nanocellulose OPEFB and nanocellulose OPF which strain the slippage movement of PVA chain during the deformation and resulting in lower elongation at break thus decreased the chain mobilityof PVA composite films [15].…”

Composites polyvinyl alcohol filled with nanocellulose from oil palm empty fruit bunch (OPEFB) and oil palm fronds (OPF) have investigated. Nanocellulose prepared by formic acid 50 wt%. Functional groups and degree of crystalline of nanocellulose were analyzed by FTIR and XRD. The degree of crystalline nanocellulose presented at 2θ at intensity of 22.26 and 21.86 for OPEFB and OPF. Amorphous part of nanocellulose at intensity of 14.68 and 15.86 for OPEFB and OPF. Functional group of nanocellulose give the same pattern for OPEFB and OPF. Nanocellulose reinforce in polyvinyl alcohol as many as 1, 5, 10 and 20% and as a comparison with polyvinyl alcohol without filler. Eight of composite films and one of vinyl alcohol film have studied mechanical properties such as tensile strength and elongation at break, and also functional groups. The tensile strength of OPF 5% and 10% increased than polyvinyl alcohol matrix. Tensile strength OPEFB 10% slightly increase from polyvinyl alcohol. The elongation of composites both OPEFB and OPF decreased with increased of nanocellulose loading.
