Wide-angle X-ray scattering (WAXS) measurements were performed using a laboratory powder X-ray diffractometer (XPert PRO, PANalytical). The X-ray tube was operated at 45 kV and 40 mA with Cu Kα radiation (0.1542 nm). The LIG-E material was scrapped off the cellulose paper and gently placed on a zero-diffraction plate. Measurements were performed from 2θ = 8° to 2θ = 100° with a step size of 0.20°. The length of the scattering vector, q, (in nm -1 ) is given by 𝑞 = 4𝜋/𝜆 sin(𝜃), with 2θ being the scattering angle and λ the X-ray wavelength (λCu,Kα = 0.1542 nm). The three main peaks considered are the (002), ( ) and ( ) peaks. The shoulders observed on the and peaks are attributed to higher order planes, namely (004) and (006), respectively, and were not accounted for during the fitting process due to their minor contributions. Crystallite dimensions were calculated using the Scherrer equation, which considers the broadening of scattering peaks in reciprocal space . Each peak was fitted individually using a Gaussian peak function on top of a linear background, as detailed elsewhere . The crystallites dimensions were estimated using :
