“…Unbleached and bleached Kraft cellulose pulp fibers modified with oleic acid in cold plasma conditions have been used. It was found that thermal stability of cellulose pulp fibers composites is higher than that of pure LDPE [25]. Bleached cellulose pulp fibers are more efficient in enhancement of composites properties.…”

“…Both fillers show decreased coefficients of the linear thermal expansion of the HDPE matrix in the flow direction. Cellulose composites containing up to 10 wt% cellulose pulp fibers with low-density polyethylene (LDPE) were fabricated by Sdrobiş et al (2012). Unbleached and bleached Kraft cellulose pulp fibers modified with oleic acid in cold plasma conditions have been used.…”

Jute cellulose composite (JCC), bamboo cellulose composite (BCC), untreated hybrid jute-bamboo fiber composite (UJBC), and jute-bamboo cellulose hybrid biocomposite (JBCC) were fabricated. All cellulose hybrid composites were fabricated with chemical treated jute-bamboo cellulose fiber at 1 : 1 weight ratio and low-density polyethylene (LDPE). The effect of chemical treatment and fiber loading on the thermal, mechanical, and morphological properties of composites was investigated. Treated jute and bamboo cellulose were characterized by Fourier transform infrared spectroscopy (FTIR) to confirm the effectiveness of treatment. All composites were characterized by tensile testing, thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). Additionally, surface morphology and water absorption test was reported. The FTIR results revealed that jute and bamboo cellulose prepared are identical to commercial cellulose. The tensile strength and Young's modulus of composites are optimum at 10 weight percentage (wt%) fibers loading. All cellulose composites showed high onset decomposition temperature. At 10 wt% fiber loading, JBCC shows highest activation energy followed by BCC and JCC. Significant reduction in crystallinity index was shown by BCC which reduced by 14%. JBCC shows the lowest water absorption up to 43 times lower compared to UJBC. The significant improved mechanical and morphological properties of treated cellulose hybrid composites are further supported by SEM images.

“…Low-density polyethylene has been studied as a composite matrix owing to its significant material flexibility, strength and durability (Kuila et al 2011). In the literature, several natural fibres, such as coconut fiber, cellulose pulp fiber, doum palm fiber and banana stem fibre have been used to reinforce the low-density polyethylene (Brahmakumar et al 2005;Sdrobiş et al 2012;Khan et al 2013). The objective of the present study was to evaluate the feasibility of using cassava bagasse in composites.…”

“…Previously, cellulose-based micro-and nanomaterials have been used as fillers in PE matrices (Bataille et al 1990;Herrera-Franco and Aguilar-Vega 1997;Panaitescu et al 2007b;Tajeddin et al 2009;Shumigin et al 2011;Sdrobiş et al 2012;Pöllänen et al 2013;Kiziltas et al 2016a). The cellulose-filled PE composites are melt-mixed using a Brabender mixer, a conical twinscrew microcompounder, and a twin-screw extruder (TSE) (Shumigin et al 2011;Sdrobiş et al 2012;Kiziltas et al 2016a). The chemical compatibility of hydrophilic cellulose and hydrophobic PE, in addition to the cellulose dispersion in PE matrices, have been improved with the addition of a coupling agent, chemical treatment of the cellulose surface, and a carrier system for cellulose-filled PE micro-and nanocomposites (Sdrobiş et al 2012;Pöllänen et al 2013;Kiziltas et al 2016a).…”

An extensional flow mixture (EFM) system was studied, with the goal of achieving better distributive and dispersive mixing. The effects of different mixing strategies (masterbatch method (MB), polyethylene-grafted maleic anhydride (PE-g-MA) as a compatibilizer, and compounding devices, such as a single screw extruder (SSE), a twin screw extruder (TSE), and an extensional flow mixer (EFM)) on the mechanical, thermal, rheological, and morphological properties of ultrafine cellulose (UFC)-filled highdensity polyethylene (HDPE) composites were investigated. Maximum tensile strength (17.7 MPa), tensile modulus (0.88 GPa), flexural strength (18.8 MPa), and flexural modulus (0.63 GPa) were obtained from the MB compounding method. The maximum stress-strain (13.8%) was obtained with EFM compounding. Polymer composites from SSE and SSE/EFM compounding methods with PE-g-MA exhibited slightly higher crystallinity compared with other compounding methods. The storage modulus of the samples prepared with the MB method was higher than those prepared with the SSE compounding method. The UFC-filled HDPE composites from the EFM compounding process exhibited lower melt viscosities than the other composites at high shear rates. Scanning electron microscopy (SEM) images showed the cellulose to be distributed and dispersed reasonably well in the HDPE matrix when using a coupling agent in combination with the MB and EFM compounding methods.
