"protocol": "bP has been directly exfoliated in the liquid vinyl monomer, methyl methacrylate (MMA), without solvents, and after the addition of a radical initiator, the hybrid material has been obtained by in situ radical polymerization. For comparison purposes, PMMA-based composites have also been prepared by the direct bP exfoliation in polymer solution or by starting from bPn previously exfoliated by LPE with DMSO and successively dispersed in the PMMA matrix.In Situ Radical Polymerization. A Schlenk tube (10 mL) equipped with a magnetic stirrer and previously degassed, backfilled three times with nitrogen, was loaded with the MMA_bPn or Sty_bPn or NVP_bPn suspensions (previously prepared). A weighted amount of AIBN (2 wt % with respect to the monomer) was added, and the tube was placed in an oil bath (temperature and time of polymerization depending on the vinyl monomer used). The product was then dissolved in CHCl3 and precipitated in an appropriate solvent to remove unreacted monomer and polymerization byproducts: MeOH was used for PMMA and PS, while Et2O was used for PNVP. After recovering via filtration, the resulting powder was dried under vacuum until a constant weight was achieved."
