“…Recently, lots of research has been carried out to the use of biopolymers because of their inherent properties like biodegradability, non‐toxicity, low cost, and ease in availability especially in the field of packaging industry . But major problem associated with the use of biopolymer for several applications are their low mechanical and water barrier properties.…”

Cellulose nanofibers (CNFs) and nanocrystals (CNCs) are nanoscale materials obtained from nature by various physical and chemical treatments that has a strong reinforcing ability. CNFs and CNCs have different size, shape, viscosity, and other properties. This study focusses on comparative studies on reinforcing effect of CNFs and CNCs on thermoplastic starch (TPS). The nanocomposites with different weight percentage of reinforcing fillers are fabricated via solvent casting. The transparent TPS/CNF and TPS/CNC films are well characterized using dynamic mechanical analysis to study the effect of filler loading on viscoelastic behavior. All the nanocomposite films has better properties compared to neat TPS. But comparing the properties of CNFs and CNCs on the starch matrix, at some point of time, TPS/CNC composites are more transparent. But due to higher degree of entanglement, strong intermolecular attraction between starch and nanofibers, TPS/CNF composites are better, and the authors modeled the data with DMA and found that the nanofibers have better reinforcing ability and stress transfer character than CNCs. This type of comparative studies helps to find out the proper criteria to reinforce bio‐based material like starch for various applications.

“…Thermoplastic cassava starch was reinforced with cassava baggase cellulose nanofibrils [10]. Cellulose microfibrils from potato tuber cell waxy starch cellulose nanocrystals were also added to TPS films [2,11]. All results showed that the addition of cellulose nanofibers increases the mechanical performance of TPS films.…”

Thermoplastic starch-polyvinyl alcohol composite films were prepared by casting method with cellulose nanofibers as reinforcement agent and glycerol as plasticizer. The obtained cellulose nanofibers with a diameter of 27.23 ± 8.21 nm were isolated from oil palm empty fruit bunches (OPEFBs) by mechanical treatment. The addition of cellulose nanofibers until 3 wt% increased tensile strength and crystallinity of the composite films. In contrast, it decreased their elongation at break and water vapor transmission rate. Meanwhile, the addition of glycerol increased elongation at break and water vapor transmission rate of film matrix but lowers tensile strength of composite films.

IntroductionRecently a growing interest has been shown in the application of biopolymers as packaging materials in order to reduce the environmental pollution caused by plastic waste and to achieve sustainable development. Starch is considered as one of the most promising biopolymers because it is readily available, cheap and biodegradable. Starch is a semicrystalline polymer and it represents the major form of stored carbohydrates in plants. Starch is a mixture of two substances composed of α-D glucopyranosyl repeating units, an essentially linear polysaccharide-amylose and a highly branched polysaccharideamylopectin. One of the major problems with granular starch is its limited processability, which can be improved by the use of plasticizers. Thermoplastic starch can be obtained by the destruction of the starch granules in the presence of plasticizers under specific conditions. Polyols such as glycerol, glycols as well as water are the most widely used plasticizers [1][2][3]. The main disadvantages of TPS are its pronounced hydrophilic character and inadequate mechanical properties. The inferior properties of TPS can be improved by the incorporation of other materials (natural fibers, nanoclays, or other biodegradable polymers) [1,2,[4][5][6][7][8][9][10][11].A considerable number of papers deal with the effect of natural fibers on the properties of thermoplastic starch. Most of them study the influence of fiber type and amount usually by determining properties at one or two fiber contents. All kinds of fibers have been used as filler in TPS including various forms of cellulose [6,[12][13][14][15][16][17][18][19][20][21][22][23][24], jute [18,[25][26][27], sisal [28][29][30][31][32][33], wheat straw [13], flax [23,34] hemp [13,28,35,36], cotton [13,37,38], flax [19,39], ramie [20,40].According to the existing literature a relatively small number of papers have been published which consider the practical relevance of TPS/wood composites [7,[41][42][43][44][45][46]. There are even fewer paper about systematic experiments carried out as a function of fiber content in a wide composition range [2,41,42], furthermore, it is very difficult to find publications on the effect of processing methods on the properties of TPS/wood composites. In our earlier work we investigated different TPS/wood composites prepared by injection molding [47].
