Different compatibility approaches to improve the thermal and mechanical properties of EVA/starch composites

“…The decrease in tensile strength and elongation at break of EVA/starch composites suggests that the introduction of starch particles in EVA matrix produces an important weakness in the bulk due to poor interactions between the EVA matrix and the starch particles. This is also enhanced by the poor compatibility between EVA and starch . It has been reported that the incompatible composites show a weak interfacial adhesion, which provides a site for failure initiation.…”

“…shows also a significant improvement of Young's modulus and the tensile strength for the composites with 20–30 wt% starch. According to Rohani et al , the increased tensile strength in compatibilized LDPE/starch composites with PE ‐g‐ MA has been ascribed to the positive impact of the compatibilizer on the stress transfer which hinders the interfacial debonding. This leads to enhanced interfacial adhesion between the matrix and the starch, and subsequently an increase in the mechanical properties.…”

“…Further, Kahar et al have also reported that PE ‐g‐ GMA compatibilizer significantly increased the tensile strength of high‐density polyethylene (HDPE)‐natural rubber (NR)/Thermolplastic Starch (TPS) blends and this have been ascribed to improved interactions at the interphase between TPS and HDPE/NR. Rohani et al have demonstrated that the mechanical properties of LDPE/(TPS)‐kenaf fiber composites were improved in the presence of PE ‐g‐ MA. Moreover, a reduction in water uptake of the composites was also observed.…”

“…As a matter of facts, several studies have been carried out for improving the compatibility of starch-polymer blends including the starch modification [7][8][9][10][11][12], the addition of plasticizer [13,14], the polymer modification [15,16], and the compatibilization with coupling agents [17,18]. The compatibilization of polymer blends containing starch can be performed either by reactive extrusion [19][20][21][22][23] or by addition of a coupling agent [24][25][26][27]. Pedroso and Rosa.…”

Fabrication and properties of polyaniline/ramie composite fabric based on in situ polymerization

“…4 Among them, polyaniline has drawn enormous attention from researchers and industry people because of its low cost, simple fabrication, high conductivity and better chemical stability compared to other conductive polymers. 5,6 Polyaniline has been widely used in solar cells, 7 chemical sensors, 8 electromechanical devices, 9 electromagnetic shielding devices, 10 filtration 11 and antistatic materials 12 due to its electrochemical activity and electrochromic properties. 13 Polyaniline (in its emeraldine base with the same number of oxidation units and reduction units) becomes electrically conductive after doping with protonic acid.…”
