“…The results of the M-DAG morphological analysis (Figure 2a) show the morphology of M-DAG particles that are mutually unified. Petra et al [17] carried out monoacylglycerol (MAG) encapsulation and showed the morphology of MAG which was round with various sizes. The manufacture of M-DAG powder used in this study was carried out by means of coarse filtering with manual pressing techniques to produce a powder in the form of pellets.…”

The antistatic bionanocomposites could be synthesised using mono-diacylglycerols (M-DAG) as a antistatic agent, cellulose nanocrystals (CNC) as a reinforcement, and polypropylene (PP) as an termoplastic matrix. The purpose of this study was to determine the physical characteristics of the raw materials for the synthesis of antistatic bionanocomposites. Characteristics of the raw materials consists of morphology analysis using scanning electron microscopy (SEM), degree of crystallinity and particle size analysis using X-ray diffraction (XRD), Infrared spectrum analysis using fourier transform infrared (FT-IR), thermal properties analysis using differential Scanning Calorimetry (DSC) and chemical characteristics analysis using Gas Chromatography – Flame Ionization Detector (GC-FID). The results of this research shows that the morphology analysis shows the particle distribution of M-DAG is uniform and not separated from each other, while the particle distribution of CNC is not uniform and separated from each other. The XRD diffractogram of M-DAG shows that the peaks at 19,508°, 20,401°, 22,607°, and 23,973° representing the diffraction structure of glycerol monostearate, particle sizes ranging between 0.1050 to 1.7814 nm with an average was 1.0460 nm, 92.85 % degree of crystallinity, and 7.15 % amorphous components. The XRD diffractogram of CNC shows that the peaks at 5.8530° and 22.58° representing the diffraction structure of cellulose I, particle sizes ranging between 4.7364 to 79.0949 nm with an average was 41.9157 nm, 98.95 % degree of crystallinity, and 1.05 % amorphous components. The FT-IR spectrum of M-DAG shows that the most significant changes in spectrum were in the region between 3500 cm-1 to 2800 cm-1 and 1850 cm-1 to 1650 cm-1. The FT-IR spectrum of CNC shows that the most significant changes in spectrum were in the region between 3700 cm-1 to 2500 cm-1, 1700 cm-1 to 1550 cm-1, and 900 cm-1 to 800 cm-1. The thermal properties of M-DAG, CNC, and PP shows that the melting temperature (Tm) were 48.41 – 72.78, 241.65 – 323.74, 163 °C respectively. The chemical characteristics of M-DAG obtained 33.86 % MAG, 27.99 % DAG, 2.01 % TAG, 2.85 % FFA, 3.37 % water, and 0.15 ash. The supporting materials consists of maleic anhydrate polypropylene (MAPP), antioxidant (AO), dan mineral oil (MO) were also identified.

“…Supercritical fluid assisted atomization introduced by hydrodynamic cavitation mixer was used by Wang et al, to produce sodium cellulose sulphate microparticles with well-defined spherical morphologies and controlled particle size distributions in aqueous solution [7]. In some cases, emulsions and suspensions are treated by supercritical assisted processes, such as the rotenone coprecipitation with biodegradable polymers studied by Martin et al [8], and the encapsulation of 1-monoacylglycerols in an hydrophilic carrier by supercritical assisted atomization of emulsions reported in the work of Ševčíková et al [9] Supercritical assisted atomization technology is also applicable to obtain products for medical purposes, such as the production of composite polymer-Fe3O4 microparticles [10], and the production of nanostructured chitosan-hydroxyapatite microparticles [11], as presented by Reverchon et al In this work, PGSS-drying has been employed as drying method. By PGSS-drying technology [12], the water content of an aqueous solution is eliminated, and a dry micronized product is obtained.…”
