“…[1][2][3][4] In recent years, great research efforts have been made on PLA to reduce its cost and to improve its performance. For instance, PLA were blended with ductile biodegradable polymers, e.g., polycaprolactone [5] and poly(butylene adipate-co-terephthalate), [2] natural fibers (such as bamboo fiber, [6] wood flour, [7] hemp fibers, [8] and sugar beet pulp [9] ), starch, [10] and inorganic nanoparticles. [4] The resulting PLA blends and composites displayed a wide range of properties.…”

When containing extra water, soy protein concentrate (SPC) can behave like a plastic melt rather than particulate filler in blending process. In this study, blends of formulated SPC and poly(lactic acid) (PLA) were prepared. The effects of glycerol and water added to SPC on phase morphology, rheological, thermal, thermal‐dynamic, and mechanical properties of the blends were investigated. The results demonstrated that water was more effective in gelating SPC and transforming it into a plastic than glycerol. With extra water added, SPC in the resulting blend existed as stretched threads with certain degree of interconnectivity between the threads. In contrast, with only glycerol added, SPC existed as large SPC agglomerates. Consequently, the blends made from extra water‐containing SPC exhibited higher mechanical, thermal‐dynamic, and rheological properties.magnified image

“…Among biodegradable polyester blends, those from glassy poly(Llactic acid) (PLLA) or poly(D,L-lactic acid) (PDLLA) with relatively low environmental degradability and rubbery poly(e-caprolactone) (PCL) with relatively high environmental degradability have attracted much attention because of their wide variety of physical properties and biodegradability. Numerous studies have been published for PLLA (or PDLLA)/PCL blends on the effects of polymer blending ratio, molecular characteristics, compatibilizers, coupling agents, and preparation methods and conditions of the blends on their morphology (phase structure), [3][4][5][6]8,9,11,[14][15][16][17][18][19][20][21][22][23][24][25][26][27] crystallization, [4][5][6]8,9,11,14,16,18,28,29] thermal, [2,4,8,9,15,17,18,21,23,24,26,28,29] mechanical, ...…”

Summary: Two different types of biodegradable polyester composites, PLLA fiber‐reinforced PCL and PCL/PLLA blend films were prepared at PCL/PLLA ratio of 88/12 (w/w), together with pure PCL and PLLA films. Their enzymatic degradation was investigated by the use of Rhizopus arrhizus lipase and proteinase K as degradation enzymes for PCL and PLLA chains, respectively. In the FRP film, the presence of PLLA fibers accelerated the lipase‐catalyzed enzymatic degradation of PCL matrix compared with that in the pure PCL film, whereas in the blend film, the presence of PLLA chains dissolved in the continuous PCL‐rich domain retarded the lipase‐catalyzed enzymatic degradation of PCL chains. In contrast, in the FRP film, the proteinase K‐catalyzed enzymatic degradation of PLLA fibers was disturbed compared with that of the pure PLLA film, whereas in the blend film, the proteinase K‐catalyzed enzymatic degradation rate of particulate PLLA‐rich domains was higher than that of pure PLLA film. The reasons for aforementioned enhanced and disturbed enzymatic degradation are discussed.Normalized PCL weight loss of pure PCL, FRP, and blend films as a function of Rhizopus arrhizus lipase‐catalyzed enzymatic degradation time.magnified imageNormalized PCL weight loss of pure PCL, FRP, and blend films as a function of Rhizopus arrhizus lipase‐catalyzed enzymatic degradation time.
