“…polycaprolactone (PCL) [7], poly(hydroxyl butyrate) [9] and poly(lactic acid) [10], in order to improve their properties maintaining the biodegradation capacity of the material. Among them, PCL is a promising synthetic biodegradable material, because of its very high flexibility and its hydrophobic nature [11]. It is also one of the more commercially available biodegradable polymers.…”

Thermoplastic starch (TPS)/polycaprolactone (PCL) blends were obtained by melt mixing. First, the best formulation of thermoplastic starch (starch, plasticizer and additives) was studied. The obtained films were characterized by means of differential scanning calorimetry, DSC (melting temperature and crystallinity degree); thermogravimetric analysis, TGA (real composition of the blend and thermal stability); tensile tests (mechanical properties); infrared spectroscopy, FTIR (interactions between components); scanning electron microscopy, SEM (morphology); and water absorption tests. The effect of PCL/TPS ratio on the previously mentioned characteristics and properties were studied. In addition, the effect of using PCL modified with maleic anhydride as compatibilizer was also analyzed. An optimal compatibilizer content was found improving the mechanical properties and slowing down the degradation rate in soil of the blends. On the other hand, a slight increase in the water absorption of the blends was found in comparison with the noncompatibilized ones.

“…Recently, synthetic LDPE composite can be prepared by blending it with natural fibers [2,3]. Natural fibers can be classified based on their origin such as vegetable/plants (jute, hemp, kenaf, cotton, coir, pineapple leaf fiber, banana stem, bamboo, wheat and rice straw), animals (animal hairs and silk fiber) or mineral (asbestos, ceramic and metal) [2,[6][7][8][9][10]. Natural fibers also exhibit various mechanical and physical properties such as high stiffness, low density (for example plant fiber) and low cost.…”

“…According to Munawar et al, [11] natural fibers have recently attracted the attention of researchers to use as reinforcement material for different kind of polymer matrix because of their advantages over other established materials. They are fully biodegradable, abundantly available and renewable [2,[8][9][10]. Basically, the amount of carbon dioxide (CO 2) released from the combustion and landfill process of natural fibers is neutral with respect to the assimilated amount during their growth process [10].…”

Natural fibers become most important reinforcement materials for commercial thermoplastic as it can easily biodegraded, high specific strength, abundant, renewable and easy processing. In this study, a partially biodegradable composite was prepared by melt-mixing of low density polyethylene (LDPE) with Pandanus amaryllifolius fiber (PAF). The effect of the PAF content on composite properties was investigated. Result demonstrated that the increasing of PAF content increased the density and water absorption of the composite. Tensile modulus of the composite also increase from 10.3 MPa (PAF content = 0 wt%) to 121 MPa (PAF content = 50 wt%). However the increasing of PAF content also resulted in a decreasing of tensile strength, impact strength and elongation at break of the composite.

In the present work, polycaprolactone composites are prepared in a twin‐screw extruder with different amounts of cellulose fibers from several sources (obtained from lignocellulosic curauá and jute, commercial cellulose samples with different lengths, and amorphized cellulose obtained by ball milling), maintaining the processing time and temperature. X‐ray diffraction reveal that almost all cellulose fibers act as nucleating agents for the polymer matrix, resulting in increase crystallinity index of the composites. The experiments with the commercial cellulose fibers indicate that shorter fibers promoted stronger nucleation effect. At low content (2 wt%), the composite PCL‐amorphized cellulose has improve thermal resistance to degradation in relation to the neat PCL. Dynamic‐mechanical analysis shows an increase in the modulus of the composites containing 5 and 20 wt% fibers.
