“…It has been reported that the biodegradation of poly(vinyl alcohol) (PVA) could be accelerated by additional sugars 93 and vinyl sugar. 94 As described, the suPLA exhibited higher moisture adsorption than the neat PLA. Therefore, the moisture adsorption function of suPLA might also promote the biodegradation effect of the sample.…”

Exploring the application of biodegradable/bioplastic coating material for eco-friendly and sustainable packaging is one of the global challenges being tackled. In this context, we propose (i) the synthesis of multibranched polylactic acid (PLA) using table sugar mainly composed of sucrose as a core initiator, and (ii) a model formula for sugar-based PLA (suPLA) and its diacrylate blends as a UV LED-curable coating. The synthesis of suPLA through ring-opening polymerization (ROP) was optimized by sugar: l-lactide (L-LA) molar ratio, temperature, and reaction time. suPLA, with a M w of ∼1000 g/mol, was obtained with a maximum yield of around 80%. To establish a model UV LED-curable bioplastic-based coating, the suPLA with different content was formulated in tripropylene glycol diacrylate (TPGDA) as a diluent monomer. The influence of curing time (0–60 s) on double bond conversion for turning the liquid coating to a solid film of the suPLA/TPGDA blending system was assessed. Aiming to validate the influence of the curing degree, changes in the chemical function, thermal stability, glass transition temperature, crystallization temperature, and enthalpy were also characterized. By increasing the suPLA content, the tensile tests on the UV LED-cured suPLA-TPGDA films showed significant improvement in terms of toughness. The coating surface morphologies and optical properties (i.e., gloss value, color difference, yellowness, and whiteness indexes) were also determined. It is worth noting that the sugar molecule and multibranched structure play an important role in moisture absorption. The biodegradation test demonstrated that the UV LED-cured suPLA-TPGDA film exhibited biodegradation phenomena, as analyzed from CO2 production, physical appearance, changes of mass, chemical functions, and thermal stability. The current study showed that the suPLA and its diacrylate blends are promising biobased, printable, and UV LED-curable coating prototypes to create a tough film for a sustainable packaging approach in the future.

“…The combination of these monomers with hydrophobic ones (e.g., methyl methacrylate) can lead to amphiphilic copolymers with a wide range of properties and applications. Typically, amphiphilic polymers, such as sugar-based polymers, are widely used in applications that require biocompatibility and/or biodegradability (Barros, Petrova, & Singh, 2010;Cheng & Gross, 2010;Feng et al, 2010;Galgali, Puntambekar, Gokhale, & Varma, 2004;Miura, 2007;Patil et al, 1997;Shantha & Harding, 2002;Takasu, Baba, & Hirabayashi, 2008).…”

“…Forcada et al [7,8] studied the emulsion copolymerization of 3-MDG for the production of microgels for biomedical applications. Takasu et al [9] investigated the seeded emulsion copolymerization of VAc with vinyl sugars and focused their investigations on the resulting accelerated rate of biodegradation of the material. On the other hand, Yaacoub and co-workers widely investigated the 3-MDG homopolymerization in emulsion at low solids content from 5 to 20 wt % [10].…”

Abstract:The exploration of a renewable resource for the preparation of waterborne copolymers was conducted. Low molar mass sugar resources were selected for their wide availability. A fructose-based monomer (MF) bearing a methacrylate radically polymerizable group was successfully synthesized. The latter was shown to be able to homopolymerize in emulsion. The high T g of the resulting polymer (about 115 • C) makes it of particular interest for adhesive and coating applications where hard materials are necessary to ensure valuable properties. As a result, its incorporation in waterborne acrylic containing formulations as an equivalent to petrochemical-based methyl methacrylate was investigated. It was found that the bio-based monomer exhibited similar behavior to that of common methacrylates, as shown by polymerization kinetics and particle size evolution. Furthermore, the homogeneous incorporation of the sugar units into the acrylate chains was confirmed by a unique glass transition temperature in differential scanning calorimeter (DSC). The potential of MF for the production of waterborne copolymers was greatly valued by the successful increase of formulation solids content up to 45 wt %. Interestingly, polymer insolubility in tetrahydrofurane increased with time due to further reactions occurring in storage. Most likely, the partial deprotection of sugar units was the reason for the creation of hydrogen bonding and, thus, physically insoluble entangled chains. This behavior highlights opportunities to make use of hydroxyl groups either for further functionalization or, eventually, for achieving enhanced adhesion on casted substrates.
