“…Among these synthetic polymers, PLGA copolymer, which consists of PLA and PGA, has especially attracted attention because its mechanical properties and degradation period could be controlled by adjusting compositions of PLA and PGA [ 9 , 10 ]. For that reason, PLGA has been extensively applied in various fields, including orthopedic fixation materials [ 11 , 12 ], guided bone regeneration (GBR) [ 13 , 14 ], artificial skin [ 15 , 16 ], wound dressing [ 17 , 18 ] and drug carriers [ 19 , 20 ]. An ideal material with high strength, stiffness, and toughness would be desirable for these applications [ 21 , 22 , 23 ].…”
