Effect of Selected Commercial Plasticizers on Mechanical, Thermal, and Morphological Properties of Poly(3-hydroxybutyrate)/ Poly(lactic acid)/Plasticizer Biodegradable Blends for Three-Dimensional (3D) Print
Menčík, Přemysl; Přikryl, Radek; Stehnová, Ivana; Melčová, Veronika; Kontárová, Soňa; Figalla, Silvestr; Alexy, Pavol (MDPI, 2018-10-03)This paper explores the influence of selected commercial plasticizers structure, which are based on esters of citric acid, on mechanical and thermal properties of Poly(3-hydroxybutyrate)/Poly(lactic acid)/Plasticizer ... -
Printability, Mechanical and Thermal Properties of Poly(3-Hydroxybutyrate)-Poly(Lactic Acid)-Plasticizer Blends for Three-Dimensional (3D) Printing
Kontárová, Soňa; Přikryl, Radek; Melčová, Veronika; Menčík, Přemysl; Horálek, Matyáš; Figalla, Silvestr; Plavec, Roderik; Feranc, Jozef; Sadílek, Jiří; Pospíšilová, Aneta (MDPI, 2020-10-23)This paper investigates the effect of plasticizer structure on especially the printability and mechanical and thermal properties of poly(3-hydroxybutyrate)-poly(lactic acid)-plasticizer biodegradable blends. Three plasticizers, ... -
Recycling possibilities of bioplastics based on PLA/PHB blends
Plavec, Roderik; Hlaváčiková, Slávka; Omaníková, Leona; Feranc, Jozef; Vanovčanová, Zuzana; Tomanová, Katarína; Bočkaj, Ján; Kruželák, Ján; Medlenová, Elena; Gálisová, Ivana; Danišová, Lucia; Přikryl, Radek; Figalla, Silvestr; Melčová, Veronika; Alexy, Pavol (Elsevier, 2020-09-29)The study is focused on modelling the evaluation of recyclability of the biodegradable blend using multiple extrusion of selected composition of PLA/PHB blend which had been more deeply studied before. It was shown that ... -
Transesterification of Lactic Acid Oligomers with Ethanol, a Way to Anhydrous Ethyl Lactate: A Kinetic Study
Figalla, Silvestr; Petrůj, Jaroslav; Švestková, Tereza (MDPI, 2018-08-15)A new method for the preparation of anhydrous ethyl ester of lactic acid was studied. The selected method is based on catalytic transesterification of lactic acid oligomers, which were prepared for this purpose by autocatalytic ...
