“…The results are described by the higher thermal stability of cellulose fibers compared to starch [4]. The weight loss decreased with raising of fibers contents due to the composites had lower water content, when compared to the non-reinforced TPS, at equilibrium [5].…”

Abstract. Biocomposites sheets were prepared by compression molding from mixtures of corn starch plasticized by glycerol as matrix and cellulose fibers, extracted from used office paper, as reinforcement filler with contents ranging from 0 to 8% wt/wt of fibers to matrix. Properties of composites were determined by mechanical tensile test, differential scanning calorimetry, thermogravimetric analysis, water absorption measurement, and scanning electron microscopy. The results showed that higher fibers content raised the tensile strength and elastic modulus up to 109% and 112%, respectively, when compared to the non-reinforced thermoplastic starch (TPS). The addition of the fibers improved the thermal resistance and decreased the water absorption up to 63.6%. Scanning electron microscopy illustrated a good adhesion between matrix and fibers.

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].

“…Due to its biodegradability, low cost, and worldwide availability, starch in the form of thermoplastic starch (TPS) has been extensively studied as a main component in the production of biodegradable materials. TPS is usually obtained by destroying the crystalline structure of native starch through an extrusion process in the presence of plasticizers, such as glycerol [2][3][4] . Unfortunately, TPS-based materials are hygroscopic and have limited performance.…”

Poly(lactic acid)/thermoplastic starch sheets: effect of adipate esters on the morphological, mechanical and barrier properties

et al. 2016

SbstractBlends of poly(lactic acid) (PLA) and thermoplastic starch (TPS) plasticized with adipate esters (diisodecyl adipate and diethyl adipate) having different molecular weight were used to produce sheets. The calendering-extrusion process at a pilot scale was used, and the mechanical, barrier, and morphological characterization of the obtained materials were performed. The increase in the TPS content affected the mechanical properties of the sheets by increasing the elongation and decreasing the rigidity. TPS conferred a more hydrophilic character to the sheets, as observed from the water vapor permeability results. The sheets plasticized with diisodecyl adipate (DIA), having a higher molecular weight, had better mechanical and barrier properties than diethyl adipate (DEA) plasticized sheets, indicating that DIA was more effective as plasticizer. Micrographs obtained by confocal laser microscopy and scanning electron microscopy showed different morphologies when different proportions of PLA and TPS were used (dispersed or co-continuous structures), which were strongly associated with the mechanical and barrier properties.
