Biodegradable poly(butylene adipate-co-terephthalate) (PBAT) films incorporated with different levels of the antimicrobial peptide nisin were developed by melt processing. Structural, morphological, thermal, mechanical, and antimicrobial properties of the films were determined. The X-ray diffraction patterns exhibited decreasing levels of intensity at 2h values as the concentration of nisin increased. Scanning electron microscopy showed a heterogeneous morphology when higher amounts of nisin were incorporated. The antimicrobial films tested presented no significant differences in the melting temperature (123-1258C), and the crystallization temperature ranged from 69 to 758C. The addition of nisin caused no significant modification in tensile strength values. However, results of Young's modulus and deformation at break differed significantly among samples. Active films demonstrated inhibition against the Gram-positive bacterium Listeria monocytogenes. These results demonstrated that PBAT/nisin films produced by melt processing present a great potential for use as active food packaging materials aiming enhanced food safety.

“…For each material three specimens are tested. As PBAT has a very low degree of crystallinity , the degree of crystallinity Χ c of the polymer mixtures was calculated on the basis of the heat of fusion of the sample Δ H f , and of its weight fraction of PHBV Φ . The heat of fusion of 100% crystalline PHBV and PBAT are Δ H 0 = 109 J/g and 114 J/g, respectively :

X_{normalc} = \frac{Δ H_{normalf}}{Δ H_{0} \cdot Φ} \cdot 100.

“…Only Javadi et al investigated the influence of the polymer weight ratio of three commercial PHBV/PBAT blends in solid and microcellular materials . Functionalized OMMT turned out to be compatible with PHBV as well as with PBAT . Another studies reported on the improvement of properties by addition of nanoclay to PHBV and PBAT .…”

Biopolymers are gaining increasing interest because of decline of mineral oil reserves, increasing waste problem, and increasing consciousness of society for environmental problems. However, competitiveness of biopolymers compared with conventional plastics is still limited due to partly insufficient properties and high prices. This study investigates the influence of blending of poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) with poly(butylene adipate-co-terephthalate) (PBAT) as well as the influence of addition of functionalized montmorillonite (OMMT) to the blends on morphology and thermal behavior. Dispersion state and morphology of the nanocomposites are studied by X-ray diffraction as well as scanning electron microscopy. Thermal stability is studied by thermogravimetric analysis and crystallization behavior is studied by differential scanning calorimetry and polarized optical microscopy. With respect to the morphology for the blends it can be seen that the immiscible biopolymers PHBV and PBAT are distributed in interlocking zones. There is a good dispersion and homogeneous distribution of OMMT within the biopolymer blends. The addition of 50% or more PBAT to PHBV as well as the insertion of OMMT enhances thermal stability of PHBV. In the blends, the addition of PBAT retards crystallization of PHBV. The OMMT acts as nucleating agent leading in total to more but less perfect crystals in the blends, and the crystallization slows further due to constraint in the movement of polymer chains. These results contribute to the understanding of the structure-properties relationship of bionanocomposite materials for packaging applications. POLYM. COMPOS., 36:2051-2058, 2015

“…The biological degradation of PBAT has been thoroughly investigated [2][3][4]. PBAT can be used to produce fibers [5,6], textile, films [7] (such as mulching films) and packaging materials [8,9]. Moreover, PBAT composites and modified PBAT have been widely investigated in order to prepare value-added products, such as conductive [10] and antimicrobial materials [11][12][13][14][15][16], and meanwhile to minimize the cost.…”
