“…It is widely accepted that the use of long-lasting polymers for short-term and disposable applications, such as packaging, is not entirely satisfactory [1]. As a result, the biopolymer industry is growing rapidly since biodegradables polymers made from renewable resources have a less negative effect on the environment compared to the conventional petroleum based materials largely used in commodities [2].…”

“…Polylactide (PLA) is one of the most promising bio-based polyester for food packaging [1,2] because of its good mechanical, superior transparency, ease of processing and availability in the market [3]. In this sense, poly(lactic acid) (PLA) is one of the most attractive biopolymers with many short-term or disposable applications, such as disposable cutlery (plates, cups, lids and drinking straws), bags and film packaging [4,5].…”

Polymers derived from renewable resources are now considered as promising alternatives to traditional petro-polymers as they mitigate current environmental concerns (raw renewable materials/biodegradability). d-limonene can be found in a variety of citrus, indeed is the main component of citrus oils and one of most important contributors to citrus flavor. The incorporation of limonene in PLA matrix was evaluated and quantified by Pyrolysis Gas Chromatography Mass Spectrometry (Py-GC/MS). Transparent films were obtained after the addition of the natural compound. Mechanical properties were evaluated by tensile tests. The effect of limonene on mechanical properties of PLA films was characterized by an increase in the elongation at break and a decrease in the elastic modulus. The fracture surface structure of films was evaluated by scanning electron microscopy (SEM), and homogeneous surfaces were observed in all cases. Barrier properties were reduced due to the increase of the chain mobility produced by the d-limonene.

“…Much research has been made to reinforce PLA with typically natural plant fibres [4][5][6][7][8][9][10][11][12][13] or even with glass [26] or basalt [27] fibres to make PLA based biocomposites suitable for high temperature engineering applications. By incorporating natural plant fibres to PLA in order to increase HDT it is critical to form strong connection between the fibres and the matrix.…”

“…Despite the significant amount of research, the increase of HDT is only a few times reported, which can be related to the low modulus of plant fibres. At the same time the fibres not only increase the modulus of the PLA, but the nucleating effect of microcellulose [10,11] and nanocellulose [12,13] fibre derivates was also demonstrated, however, significant crystallinity was only proved to develop at low cooling rates as 2°C min -1 [13], 5°C min -1 [10], 10°C min -1 [11,12] by using differential scanning calorimetry (DSC) tests. By using fibres with much higher stiffness like glass [26] and basalt fibres [27] the HDT was still only increased by 9°C and 5°C respectively.…”

“…In the literature, the effect of numerous organic and inorganic materials were tested as potential nucleating agents like talc [14][15][16], talc along with Poly(Ethylene Glycol) (PEG) [17] TBC8-eb (p-tertbutylcalix(8)arene ethylebenzene) [18], Ethylene-Bis-Stearamide (EBS) [15], CaCO3, TiO2, BaSO4 [19], native starch [16], microcellulose-, [10,11] and nanocellulose derivatives [12,13], orotic acid [20], hydrazide compounds [21], ethylenebis(12-hydroxystearylamide) (EBHSA) [21], layered metal phosphonates [22], multiwall carbon nanotubes [23] and PLA stereocomplex [24]. Talc was even tested for its effect on photooxidation of PLA [28].…”

In our research, the effect of talc particle size was analysed on the thermal and mechanical properties of renewable resource based, biodegradable polymer Poly(Lactic Acid) (PLA). Various talc particles with an average particle size of 24 μm, 1.9 μm, and 0.7 μm were blend mixed with PLA in 10 and 20 mass% containing no or an additional 10 mass% of Poly(Ethylene Glycol) (PEG) to increase molecular chain mobility. It was demonstrated that with decreasing talc particle size, its nucleation ability increased as well as all of the investigated mechanical properties of the compounds, however, in case of compounds containing PEG, this tendency was the opposite according to Charpy impact strength results. The talc with the best nucleating ability was selected and a full factorial design of experiment was made to optimise the talc and PEG content and to investigate their cross-effect in the 1-3-5-10-15 mass% additive content range. Finally, the effect of mould temperature and cooling time was analysed on the crystallinity and heat deflection temperature of the final injection moulded parts.
