The recoverable energy density ( Urec) with charge–discharge efficiency (η) of 90% was improved from ∼2.9 J/cm 3 for amorphous PLLA to ∼5.7 J/cm 3 for the crystallized PLLA film at room temperature.
As a result, stunning energy storage characteristics, i.e., a giant recoverable energy density of 22.0 J cm −3 with an ultrahigh energy efficiency of 96.1% are achieved in our MLCCs. This is the highest recoverable energy density achieved in MLCCs with an efficiency surpassing 95%.
The Mw decreased in all cases, although in most cases the elastic modulus tended to increase . Autoclaving and dry heating are usually performed at temperatures equal to or higher than 120 °C. For example, PLLA at 129 °C for 60 s resulted in minimal change in tensile properties of the tested PLLA.
The Tm and degree of crystallinity are depended on the molar mass, thermal history and purity of the polymer . The density of amorphous and crystalline PLLA has been reported as 1.248 g/ml and 1.290 g/ml, respectively.
Zhou and Xanthos studied the size effect and the kinetics of the thermal degradation of PLAs and they have concluded that, in general, the thermal stability of PDLLA and its composites is higher than that of PLLA and its composites and the thermal stability of the nanocomposites is higher than that of the microcomposites .
