“…However, compared with the equivalent pure PCL, elongation at break of both composites decreased with increasing starch content. The findings of Bikiaris et al [13] regarding mechanical properties of LDPE/plasticizedstarch containing PE-g-MA compatibilizer were similar to those discussed here. It is evident that the mechanical properties strongly depend on the dispersion and phase size of starch in the PCL matrix.…”

“…Nevertheless, physical properties of PCL become significantly worse when blended with starch due to the poor compatibility between the two phases. Such an operation therefore requires a compatibilizer and/or a toughener to enhance the compatibility between the two immiscible phases and to improve the mechanical properties of the composite [13]. Studies by Bikiaris and Panayiotou [14] showed that maleic anhydridegrafted-polyethylene (PE-g-MAH) increased the compatibility between low-density polyethylene (LDPE) and plasticized starch.…”

Abstract. Starch is a natural polymer which possesses many unique properties and some shortcoming simultaneously. Some synthetic polymers are biodegradable and can be tailor-made easily. Therefore, by combining the individual advantages of starch and synthetic polymers, starch-based completely biodegradable polymers (SCBP) are potential for applications in biomedical and environmental fields. Therefore it received great attention and was extensively investigated. In this paper, the structure and characteristics of starch and some synthetic degradable polymers are briefly introduced. Then, the recent progress about the preparation of SCBP via physical blending and chemical modification is reviewed and discussed. At last, some examples have been presented to elucidate that SCBP are promising materials for various applications and their development is a good solution for reducing the consumption of petroleum resources and environmental problem.

“…This deterioration may be attributed to the difference in polar characteristics of starch and the polymer matrix, which induced poor interfacial adhesion between the two components. 35 It was also noted that the maximum amount of starch that could be incorporated within the formulation was 23 wt%, as greater proportions led to a material that could not be cast as a lm.…”

Bio-based thermoset composites from epoxidised linseed oil and expanded starch

et al. 2014

a Bio-based thermoset composites comprising epoxidised linseed oil (ELO), a bio-derived diacid crosslinker (Pripol 1009) and starch are reported. High amylose corn starch in its native, gelatinised and retrograded forms were used in the formulation to yield water resistant films with good thermal stability. The textural properties of gelatinised and retrograded starches were characterised using scanning electron microscopy and porosimetry and their thermal stability was determined using thermogravimetric analysis. The inclusion of 20% gelatinised starch significantly improved the mechanical properties of the bio-based thermoset composite with tensile strength being enhanced by 227% and Young's modulus by 166% with respect to the starch-free counterparts. Unlike in formulations comprising native starch, no visible phase separation was noticed for gelatinised-or retrograded-starch thermosets. Thermal analysis and gel time study revealed retardation of the cure process in the presence of starch. However, the presence of hydroxyl groups within the starch was likely to promote a more extensive curing process, as indicated by the higher total enthalpy of reaction obtained. This was supported by thermal stability studies, which indicated a greater proportion of crosslinked material obtained in films with higher starch content.
