“…Herein we will discuss the application of sugarcane bagasse as reinforcing filler for various polymeric materials. Different forms of fillers can be generated/produced from sugarcane bagasse waste which include sugarcane bagasse ashes (SBA), fibers (SB), nanocrystals (CNCs), cellulose and micro/nanofibers (MFC or CNF) were incorporated in various polymer matrices such as polypropylene (PP) [28], low density polyethylene (LDPE) [29] polyethylene oxide (PEO) [30], nylon [31] as well as thermosets [32,33].…”

“…The addition of the filler into the precursor (polymer monomer) increases the possibility of good dispersion and interaction between the polymer and filler. Motaung et al [31] prepared CNC/nylon nanocomposites via in situ polymerization. The CNC were added into hexamethylenediamine (i.e., nylon monomer) followed by sonication to enhance the dispersion of the CNCs.…”

Waste recycling has been the main topic of various scientific researches due to environmental management. Renewable agricultural sources such as pineapple leaf, sisal, jute, piassava, coir, and sugarcane bagasse are among agro waste, normally known as biomass, which is recently used for reinforcing polymeric materials. Sugarcane bagasse fiber residues has been extensively investigated and employed as a source of reinforcement of polymers. The major residue is normally burnt for energy supply in the sugar and alcohol industries and as a result, tons of ash is created. The ash contained inorganic components which are valuable for reinforcement in polymeric materials. This chapter reports on the use of sugarcane bagasse, sugarcane bagasse ash (SBA) and its cellulose as reinforcing fillers for polymers.

“…There are several processes used to achieve a uniformed distribution of nanoparticles in the polymer matrix, such as solution mixing where the polymer is dissolved in a solvent, and the filler is then added and dispersed, and in situ polymerization 38–41 . Even though these methods can efficiently separate and disperse nanofillers, their industrial application is limited from a cost and environmental perspective 42,43 .…”

Short‐chain‐branched‐polyethylene (SCB‐PE) is extensively used in domestic hot and cold piping systems. SCB‐PE nanocomposites using graphene nanoplatelets (GNPs) as a filler, were prepared in this work. The effect of ball‐milling as a premixing technique prior to melt‐mixing, on the crystallization and the nanomechanical properties of the composites has been studied. Two sets of SCB‐PE/GNPs nanocomposites with various filler loadings were prepared; one with and one without the ball‐milling step. The dispersion of the filler was evaluated by optical microscopy while the crystallization process was studied using differential scanning calorimetry. The nonisothermal crystallization's experimental data were analyzed using various methods. The materials' nanomechanical behavior was investigated by conducting nanoindentation tests. A finite element analysis process was developed to extract the composites' stress–strain behavior. The composites prepared with ball‐milling presented improved dispersion of GNPs in the SCB‐PE matrix, which affected the crystallization, while nanoindentation tests showed significantly enhanced mechanical properties.

Short-chain branched-Polyethylene (SCB-PE) is commonly utilized in hot and cold piping systems due to its high-temperature resistance. SCB-PE nanocomposites using graphene nanoplatelets (GNPs) as a reinforcing filler were synthesized in this work. The effect of the filler’s content and the ball-milling process on nanocomposites’ structure, tensile and shear properties was studied. Two series of nanocomposites have been prepared, one with and one without the ball-milling as a premixing step prior to the melt-mixing process. The ball-milling process induced a lower crystallinity degree of the SCB-PE nanocomposites than their solely melt-mixed counterpart. The tensile properties of the ball-milled samples presented a more profound enhancement with increasing filler content. The Ji and modified Halpin-Tsai micromechanical models were best fit to describe the experimental elastic modulus of the solely melt-mixed and the ball-milled nanocomposites, respectively. Fractography studies suggested that the detachment of the filler particles from the polymer matrix is avoided for lower GNPs contents of the ball-milled samples. Shear tests revealed that the shear strength increased and ductility decreased with increasing filler content in any case. The ball-milling process resulted in SCB-PE nanocomposites with superior mechanical properties compared to their solely melt-mixed counterparts.
