Compatibilizing effects for improving mechanical properties of biodegradable poly (lactic acid) and polycarbonate blends

Preparation and characterization of nanocomposite of maleated poly(butylene adipate-co-terephthalate) with organoclay

“…Sabet and Katbab pointed out that the incorporation of compatibilizers into the polymer/clay mixture during the blending process can be effective in increasing the degree of exfoliation of the silicate layers, and the presence of terminal hydroxylated edge groups of the modified nanolayers was responsible for the accelerated biodegradation of biopolyesters [15]. Maleic anhydridegrafting copolymers have been demonstrated to enhance the dispersion of fillers and nanoparticles in the polymer matrix [16][17][18][19][20], and the compatibilization of immiscible polymer blends [21,22].…”

Photothermal and morphological characterization of PLA/PCL polymer blends

“…PLA, PCL and their blends have been widely investigated because of a broad range of applications [16,17]. However, all kinds of blend have its limitations; for example, the melt blending of the two polymers results in poor improvement of toughness and a considerable decrease in stiffness and strength as a result of the immiscibility and weak interfacial adhesion [18][19][20][21]. For this reason, a compatibilization process is often carried out to reduce the size of the dispersed phase and/or to stabilize the morphology of the blends.…”

“…For this reason, a compatibilization process is often carried out to reduce the size of the dispersed phase and/or to stabilize the morphology of the blends. In order to improve compatibility and the blend final properties, methods such as addition of copolymers [22,23] or compatibilizer agents such as polymer grafted with maleic anhydride [21,24] and other monomers have been performed. However, in contrast to the melt blending, solution blending seems to be an effective and easy way to achieve the desired final properties of the polymer blend of PCL and PLA [1,25].…”

Mechanical characterization and morphology of polylactic acid /liquid natural rubber filled with multi walled carbon nanotubes

“…With the appropriate blend components, it is possible to improve properties such as modulus, yield stress, impact strength and tensile strength. It is therefore not surprising that PLA has been blended with both nondegradable [5][6][7] and biodegradable polymers [8][9][10][11]. Typically, the blends of two different polymers leads to incompatible blends and shows different phases of blend morphologies i.e.…”
