Self-healing green composites based on soy protein and microfibrillated cellulose

Self-healing soy protein isolate-microfibrillated cellulose (MFC-SPI) composites that incorporated poly(d,l-lactide-co-glycolide) microcapsules containing SPI (SPI-PLGA-MCs) as the healing agent were developed. SPI-PLGA-MCs prepared using a green solvent, ethyl acetate, had a protein loading of over 50%. Self-healing MFC-SPI (10 wt%) composites containing SPI-PLGA-MCs (15 wt%) had Young's modulus of about 970 MPa and strength of over 15 MPa...
