“…If the surface of the filler is incompatible with the polymer, the polymer and particle phases separate, which leads to the agglomeration of the particles [4][5][6]. The silica surface can be modified with silane coupling agents to improve adhesion between the particles and the polymer [7][8][9][10]. The coupling agent can react with OH groups of silica surface, and an attached functionalized alkyl chain is more compatible with the polymer than the bare surface of the silica.…”

A number of batch polymerizations were performed to study the effect of pristine nanoparticle loading on the properties of PMMA/silica nanocomposites prepared via RAFT polymerization. In order to improve the dispersion of silica nanoparticles in PMMA matrix, the silanol groups of the silica are functionalized with methyl methacrylate groups and modified nanoparticles were used to synthesize PMMA/modified silica nanocomposites via RAFT polymerization. Prepared samples were characterized by thermogravimetric analysis (TGA), dynamic light scattering (DLS), dynamic mechanical thermal analysis (DMTA), differential scanning calorimetry (DSC) and gel permeation chromatography (GPC). According to results, introduction of modified nanoparticles results in better thermal and mechanical properties than those of pristine nanoparticles. Also, surface modification and increasing silica nanoparticles result in variation of thermal degradation behavior of nanocomposites. The best improvement of mechanical and thermophysical properties is achieved for nanocomposites containing 7 wt. % silica nanoparticles.

“…Furthermore, the characteristic peaks of the −CO stretching and the strong broad −C–O–C– type ester stretching band occurred at 1726 and 1150 cm –1 , respectively. These broad peaks observed at 400–4000 cm –1 confirmed successful synthesis of the hydroxyl-functionalized latex nanoparticles. − 1 H NMR characterization was performed to ensure successful synthesis of the oxazolidine derivatives (Figures S2 and S3). DLS analysis was also used to investigate the particle size and its distribution to ensure successful preparation of the latex nanoparticles with a mean size of below 100 nm.…”

Photoluminescent Polymer Nanoparticles Based on Oxazolidine Derivatives for Authentication and Security Marking of Confidential Notes

Colloidal materials have widely been used to develop innovative anticounterfeiting nanoinks for information encryption. Latex nanoparticles based on methyl methacrylate (MMA) and 2-hydroxyethyl methacrylate (HEMA) bearing hydroxyl functional groups were synthesized via semicontinuous miniemulsion polymerization. The size determination of the nanoparticles and microscopic results showed mostly spherical nanoparticles with a narrow size distribution and a mean size of about 80 nm. Two oxazolidine derivatives were physically doped at the surface of the nanoparticles to prepare photoluminescent polymer nanoparticles. Hydroxyl functional groups at the surface of the nanoparticles led to their hydrogen bonding interactions with the doped luminescent compounds. Optical analysis of the photoluminescent nanoparticles displayed different fluorescence emission and UV−vis absorbance intensities based on the amount of polar groups located at the surface of colloidal nanoparticles. Reducing the particle size to below 100 nm along with increasing the surface area can assist the decrease of the light reflectance and improvement of the latex nanoparticles' efficiency in the anticounterfeiting industry. This preparation methodology can efficiently provide remarkable photoreversible anticounterfeiting nanoinks used in different applications, such as print marking, security encoded tags, labeling, probing, and handwriting.

“…It decreases the negative effects of traditional emulsiers on the nature of the emulsion. [19][20][21][22][23] Reactive emulsiers without nonyl phenol groups and alkyl phenol groups should be used, since the use of nonyl phenol ethoxylates and alkyl phenol ethoxylates is restricted in many countries for its environmental endocrine disruptors. [24][25][26][27] Reactive emulsier SR-10 can provide the micelles for radical reaction.…”
