“…A C C E P T E D ACCEPTED MANUSCRIPT 2 When considering different synthetic approaches to nanocomposite materials, miniemulsion 1 polymerization is known as a convenient and powerful technique to encapsulate a wide range of 2 different inorganic nanoparticles [9]. In this method, the droplets loaded with inorganic particles 3 ideally stay constant in size and shape.…”

“…Inorganic particles may disperse homogeneously in the organic phase when 7 they are surface modified by appropriate modifiers [11]. 8 Among different inorganic nanoparticles, silica is one of the most attractive one with several 9 favorable advantages such as relatively inexpensive, nontoxic, biocompatible, high thermal 10 resistant and especially its ability to reinforce polymer matrix's mechanical properties [12]. 11 Therefore, SiO 2 is the most frequently used nanoparticle for fabrication of polymer 12 nanocomposites [13].…”

Fourth-generation poly(aminoamide) (PAMAM) dendrimer was synthesized via a divergent method with iterative sequence Michael addition or alkylation and amidation reactions with ethylenediamine as primary core and methyl acrylate. Then, its peripheral primary amine groups were conjugated with S-(thiobenzoyl)thioglycolic acid as reversible addition-fragmentation chain transfer (RAFT) agent and poly(2-hydroxyethyl methacrylate) (P(HEMA)) was grafted onto surface via RAFT polymerization. Fourier transform infrared spectroscopy (FT-IR), proton nuclear magnetic resonance ( 1 H NMR), and dynamic light scattering (DLS) were used to approve the successful synthesis of different nanostructures. Then, fourth-generation, RAFT-conjugated fourth-generation, and P(HEMA)-grafted fourth-generation PAMAM dendrimers were examined as stimuli-responsive nanostructures. Finally, in vitro cellular cytotoxicity was applied to evaluate the biocompatibility of synthesized dendrimers and investigate the cytotoxic effect of grafted polymer using HeLa cells. As a results, fourth-generation and RAFT-conjugated fourth-generation samples showed no stimuli-responsive behavior while P(HEMA)-grafted fourth-generation PAMAM dendrimer had a LCST of 26°C. Also, fourth-generation and RAFT-conjugated fourth-generation samples were characterized as toxic compounds while grafting P(HEMA) decreased cytotoxicity significantly.

“…Furthermore, in recent years, abundant novel techniques have been worked out in great detail to elaborate hollow particles or capsules. Such techniques, worthy of notice are hard and soft templating techniques, in situ and hetero phase polymerization (20)(21)(22)(23)(24). Most of these techniques are based on the sol-gel process, and includes preparation of a silica layer on the polymeric or hybrid particles via hydrolysis and condensation of the silica precursor (4,25,26), e.g.…”

An appropriate approach has been used for the preparation of silica/P(MMA-co-St) hybrid nanoparticles through converting previously prepared inverse miniemulsions into a direct miniemulsion and consequently, using the droplet nucleation polymerization technique. In the early stage of the procedure, silica particles were synthesized from TEOS in the presence of NH 4 OH or HCl as a catalyst through a base or acid-catalyzed sol-gel process. TEOS, ethanol and tirmethoxyvinylsilan were mixed in MMA:St (50:50) to create the inverse miniemulsion I, similarly CTAB, NH 4 OH/HCl and distilled water were dispersed into MMA:St (50:50) and called inverse miniemulsion II. Then, the two mentioned inverse miniemulsions were emulsified in water to achieve direct miniemulsion. The nature of the catalyst and TEOS concentration varied, for the aims of investigation, their effect on the morphology and size of hybrid nanoparticles. This route provided a unique process for silica/polymer hybrid nanoparticles production, avoiding organic solvents. Transmission electron microscopy micrographs revealed that, the morphology of the hybrid nanoparticles can be controlled by the nature of the catalyst.
