Expected reaction scheme. As-prepared silicon nanoparticles are dispersed in methanol (left) and etched with hydrofluoric acid for 20 min. After the filtration process, the hydrogen-terminated particles are transferred into the acrylic acid (middle) and heated up to 80°C for 25 min to finish the functionalization (left).
