The impact of morphology control on the microhardness of PMMA/Boehmite hybrid nanoparticles prepared via facile aqueous one-pot process

Aluminum oxyhydroxide-doped PMMA hybrids powder prepared via facile one-pot method towards copper ion removal from aqueous solution

“…The PMMA/AlOOH nanohybrids were prepared via a facile sol-gel single-source method starting directly from relevant precursors at different pH according to the procedure described in previous work [20]. First, 2.82 g methyl methacrylate (MMA) added to 0.065 g 3-methacryloxy propyl trimethoxy silane and mixed with the solution of 0.3 g surfactant SDS in 60 ml deionized water to form micelles.…”

“…2 for experiments carried out at ambient conditions with three weight changes. The first weight loss mainly up to 150 °C (negligible) may be associated with water and oligomers remaining in the samples [20].…”

“…Thus, fewer particles with larger size are formed than occurs for acidic situations. The presence of negative ions in liquid may cause relative stability of particles by repulsive forces which in turn make hybrids as segregated particles with fairly saturated Al 3+ by hydroxyl groups [20].…”

“…The creation of PMMA and boehmite nanohybrids via the one-pot process (sol-gel-based) results in the formation of numerous chemically dynamic sites which are adsorbent in their fine structures. It is noteworthy that the sol-gel process is capable of forming the fine structures by starting the reactions directly from relevant precursors which facilitate the homogeneous mixing of organic and inorganic ingredients [20]. Adsorption is considered a smart method that permits flexibility in scheme and operation, regeneration of the adsorbent by appropriate desorption process, and it is highly effective and more economic.…”
