“…For the MESSP filled PVOH solution, the MESSP was added slowly into the conical flask after 30 min of dissolving the PVOH in the deionized water. The solutions were continuously heated and stirred for 2 h (Ooi et al 2017). The compounding formulation of the PVOH/MESSP films is shown in Table 1.…”

“…Numerous studies on the development of biocomposites and biobased-plastics using natural fillers such as starch, fruit waste, pineapple leaf, and kenaf have been conducted (Ramaraj 2006;Orchi 2008;Ooi 2011b;Kalambettu et al 2014). Ooi et al (2017) reported on the preparation and properties of oil palm ash filled polyvinyl alcohol (PVOH) films through the solution casting method. The addition of oil palm into PVOH enhanced the resistance towards water absorption and the biodegradability of the films.…”

“…However, the tensile properties of the films were reduced with the addition of oil palm ash. Moreover, the thickness of the films produced through the commercially studied solution casting method was not consistent and may affect the overall properties of the films produced (Ooi et al 2017). Thus, the membrane casting method was used to develop the films, which uses a thickness controller to spread the PVOH solution into a more consistent thickness.…”

The development of biobased-plastic through natural filler addition into polymers has been the best method to resolve numerous environmental problems caused by overconsumption and the increasing waste disposal of non-degradable plastic films. This article produced biodegradable polyvinyl alcohol (PVOH) films by adding Mimusops elengi seed shell powder (MESSP) as a filler. The membrane casting method was used to develop the films instead of using the commercially studied solution casting method to avoid inconsistency in the thickness of the casted films. Increasing the MESSP loading enhanced the tensile modulus, resistance towards water absorption, and biodegradability of the PVOH/MESSP films. However, the tensile strength and elongation at break were reduced compared with the unfilled PVOH film. Fourier transform infrared (FTIR) analysis confirmed the reduction of intermolecular bonding between the MESSP and PVOH with increasing the MESSP loading, which is responsible for the reduction in tensile strength, deformability and water absorption of the films. After soil burial exposure, unfilled PVOH films experienced swelling due to water absorption, and there was no evidence of bio-degradation after 9 weeks of exposure. Meanwhile, the PVOH/ MESSP films were prone to microorganism activity and biodegradation can be seen as early as 3 weeks after exposure to soil.

“…Many papers have focused on preparation of functional PVA-based composites by adding natural fibers to PVA. Zhong et al used oil palm ash produced through the incineration process as a blending material with PVA to prepare thermoplastic film and found that the new film had better water resistance and degradation [35]. It is suggested that cellulose nanofibers (CNF) constitute ideal nanofillers to reinforce composites [36] due to their excellent properties such as low density, high tensile strength and biodegradability [37,38].…”

Blue luminescent carbon quantum dots (CQDs) were prepared from cyanobacteria by a hydrothermal method. The PL quantum yields of the obtained CQDs was 5.30%. Cyanobacteria-based carbon quantum dots/polyvinyl alcohol/nanocellulose composite films were prepared, which could emit bright blue under UV light. FTIR characterization showed that the composite films had hydroxyl groups on the surface and no new groups were formed after combining the three materials. The photoluminescence (PL) spectra revealed that the emission of the prepared CQDs was excitation dependent. Studies on the water resistance performance and light barrier properties of the composite films showed that they possessed higher water resistance properties and better UV/infrared light barrier properties. Therefore, we report the cyanobacteria-based carbon quantum dots/polyvinyl alcohol/nanocellulose composite films have the potential to be applied in flexible packaging materials, anti-fake materials, UV/infrared light barrier materials and so on.

“…Approximately $5/tonnes are generated per year by developing countries, and the corresponding number is $50/tonnes in developed countries. In this context, it is very important to find a solution to use these agro-wastes for developing value-added materials (Ooi et al 2014).…”

The substantial release of oil palm ash into ground water has been a serious concern to the environmentalist due to the enormous generation of oil palm ash waste from oil palm incineration. The effective utilization of this agrowaste is yet to be fully exploited. In this context, herein we, investigated the potential of oil palm ash nanofiller as an effective reinforcement in epoxy-based composites. Transmission electron microscopy (TEM) revealed that the prepared oil palm ash nanoparticles had circular morphology with particle size in the range of 20 to 25 nm. X-ray diffraction patterns of the prepared oil palm ash nanoparticles revealed the crystalline nature of the oil palm ash nanoparticles. Tensile strength and tensile modulus of the epoxy composites were substantially improved to 64, 67, 70, and 75 MPa and 1.01, 1.05, 1.16, and 1.18 MPa at oil palm ash nanofiller loading of 1%, 2%, 3%, and 4%, respectively. The impact strength of nanocomposite was enhanced from 2.7015 ± 0.13 kJ/m2 to 3.98 ± 0.17kJ/m2 at 3% of oil palm ash nanofiller loading. The optimum values of mechanical properties were attained at 4% filler loading, after which further loading resulted in the decrement of mechanical properties of epoxy nanocomposite. Thermal stability of the epoxy nanocomposite was enhanced substantially to 435 °C by the incorporation of oil palm ash nanofillers. This study proved that nano-sized oil palm ash could be an efficient reinforcement in polymer composite.
