The influence of GQDs on the crystalline structures of silks was studied by WAXS,the corresponding 2D-and1D-WAXS patterns are shown in Figs 3–5,respectively.It can be observed that both the 2D-and 1D-WAXS patterns do not show any obvious difference among all the silk samples,proving that the basic structures of silks are not destroyed by the intake of GQDs,which is consistent with the results from Raman spectra.The mean crystallite size ofβ-sheets in a direction(interchain),b direction(intersheet)and c direction(along fiber axis),which is directly related to the mechanical properties of silks[42],was obtained by analyzing the main equatorial(200),(120) and meridian(002)reflections[43–46],respectively,through Scherrer formula[47,48].The results shown in Table S4 demonstrate that theβ-sheet nanocrystal size of GQDs-silks is smaller than that of controlsilk in a,b and c direction.The variation of theβ-sheet nanocrystal size in all the three directions among the GQDs-silks has no conspicuous regularity.
