Figure S1. Thickness profile of PLLA nanosheets as a function of PLLA concentrations. Figure S3 shows the results of XRD. Annealed PLLA nanosheets show the peaks at ca. 16.5˚ attributed to the crystalline of PLLA, while non-annealed PLLA nanosheets shows no peaks. Accordingly PLLA nanosheets were crystallized by thermal annealing above Tg. In comparison with two conditions of annealing temperature on the similar thickness of PLLA nanosheets, the peak value of 120oC annealed PLLA nanosheet is higher than that of 80oC. Hence, the crystallinity of 120oC annealed PLLA nanosheet is higher than that of 120oC, thus the crystallinity of PLLA nanosheets can be controlled by annealing temperature. And in both annealing conditions, the peak areas
