“…The main absorption peaks for pure PMMA and GNPs/ PMMA nanocomposite are visible at 2992 cm −1 (O CH 3 , C H stretching), 2948 cm −l (C CH 3 , C H stretching), 1729 cm −l (C O stretching), 1434 cm −1 (O CH 3 bending), 1382 cm −1 (C CH 3 bending), 1238 cm −1 (C C O stretching), 1189 cm −1 (C O C bending), 1145 cm −1 (CH 2 bending) and 753 cm −1 (C O bending). [25][26][27] There is not much research available concerning the effect of bonding interaction between the PMMA and GNPs on the FTIR spectrum of the composite. The PMMA/GNPs nanocomposites fabricated here presented similar absorption peaks as a result of the variations in the bonding interaction between PMMA and GNPs at different concentrations of the GNPs.…”

The technique for synthesis of poly (methyl methacrylate) (PMMA) by atom transfer radical polymerization has been strengthened by using graphene nanoplatelets (GNPs) to enhance the elastic properties of the polymer. In order to improve practical, economical and mechanical performance, the requirements for effective implementation of production control as a smart bulk polymer nanocomposite were determined for cost-effective bulk production. Threedimensional inspection (using an ultrasound interrogation method for the whole volume under test) confirmed the synthesis of the nanocomposite to be free of agglomeration and bubbles. As a result of this elimination of defects, an enhancement in compressive strength of 42.7% was achieved and the Rockwell hardness was increased by 19.9% through the addition of GNPs at 2 wt% by mass. The deformation and mechanical failure properties have been characterized in the mechanical enhancement of the polymer nanocomposite. Elastic parameters determined using ultrasound testing identified that changes in the structural features following the addition of these GNPs were uniquely connected to the enhancements in these elastic parameters (such as Young's modulus, Poisson's ratio, shear modulus, and microhardness) of the PMMA/GNPs nanocomposite.

“…With addition of CoNPs with and without DBSA, in the PMMA matrix, the absorption is increased showing incorporation of CoNPs in the structure of PMMA. This increase in the absorption intensity was more pronounced in the case when DBSA was added as an additive which clearly indicated that DBSA helped in better incorporation of CoNPs [4,19,21]. It can be noted that shift in the position of maximum absorption is not significant.…”

Series of Cobalt nanoparticles incorporated polymethylmethacrylate composites in the presence and absence of dodecyl-benzenesulphonic acid (DBSA-CoNPs/PMMA and CoNPs/PMMA, resp.) were synthesized by solution mixing methodology. UV-visible and FTIR techniques were used to confirm the formation of nanocomposite. UV-visible spectra of the composites showed the incorporation of filler particles in the polymer matrix. On the other hand, FTIR spectra indicated the physical interaction between the two phases of the composite. Moreover, the electrical nature of the composites was studied by plotting graphs between electrical conductivity (measured using LCR meter at 100 kHz) and contents of the filler particles as introduced in the polymer matrix. An increase in electrical conductivity was first observed with increasing filler concentration up to the critical percolation threshold value (0.5% for DBSA-CoNPs/PMMA and 1% for CoNPs/PMMA), which then dropped upon further increments in the filler content. However, at higher concentrations, a second jump in the conductivity was observed in case of DBSA-CoNPs/PMMA composites.

“…Poly(methyl methacrylate) (PMMA) is widely used in various fields such as optical sensors, light conduction, optical windows, or in biomedical, biomaterials, polymer electrolytes, molecular separations. [1][2][3][4] Nowadays, PMMA has been also used as the base to produce acrylic bone cements for artificial joint replacement, filling of bone defects, kyphoplasty, vertebroplasty. [5][6][7][8][9][10][11] Commercial bone cement is composed of two separated powder and liquid components.…”

In this study, we attempted to apply a four‐arm star poly(methyl methacrylate) (4sPMMA) as a prepolymer of acrylic bone cement. The 4sPMMA with viscosity average molecular weight of about 45 kDa was synthesized via Atom Transfer Radical Polymerization method using Activators Regenerated by Electron Transfer (ARGET ATRP). In practical use, the fine powder of precipitated 4sPMMA was changed to rigid beads followed by making sheet and pulverizing. Proton nuclear magnetic resonance (HNMR), Fourier transform infrared (FTIR) spectra of 4sPMMA beads indicated the star structure of 4sPMMA with bromide end groups (C‐Br). Scanning electron microscopy (SEM) image of 4sPMMA beads showed their random shapes with size in the range of 10‐100 μm, no traces of residual metal catalysts (Cu and Sn) were detected by Energy Dispersive X‐Ray (EDX) analysizer equipped with SEM instrument. Bone cement from 4sPMMA beads had been prepared manually and curing in rectangular and cylindrical molds. The setting characterization results showed that 4sPMMA bone cements exhibited lower maximum temperature (63.9 °C), lower setting temperature (45.6 °C), than those required in ISO 5833:2002. Other properties of 4sPMMA bone cement, such as bending strength, bending modulus and setting time met the requirements of above ISO standard.
