Abstract:The emerging areas of polymer nanocomposites, as some are already in use in industrial applications and daily commodities, have the potential of offering new technologies with all manner of prominent capabilities. The incorporation of nanomaterials into polymeric matrix provides significant improvements, such as higher mechanical, thermal or electrical properties. In these materials, interface/interphase of components play a crucial role bringing additional features on the resulting nanocomposites. Among the various preparation strategies of such materials, an appealing strategy relies on the use of click chemistry concept as a multi-purpose toolbox for both fabrication and modulation of the material characteristics. This review aims to deliver new insights to the researchers of the field by noticing effective click chemistry-based methodologies on the preparation of polymer nanocomposites and their key applications such as optic, biomedical, coatings and sensor.

“…A variant of this synthesis was proposed by An et al, starting from the triblock MeOPEG- b -PCL- b -MeOPEG to improve its hydrophilicity and temperature sensitivity. A PEG- b -P(αCl-CL- co -CL)- b -PEG triblock was prepared by polymerization of a mixture of CL and αCl-CL in the presence of MeOPEG, followed by reaction with hexamethylene diisocyanate (HMDI) to form the triblock [ 104 ] ( Figure 16 ). Segments of P(MEO 2 MA) and P(OEGMA) were grafted by the ATRP of a mixture of MEO 2 MA and OEGMA to give the final PEG- b -[PCL- g -P(MEO 2 MA- co -OEGMA)]- b -PEG (tBG2) copolymer.…”

Poly(ε-caprolactone)-Based Graft Copolymers: Synthesis Methods and Applications in the Biomedical Field: A Review

et al. 2022

Synthetic biopolymers are attractive alternatives to biobased polymers, especially because they rarely induce an immune response in a living organism. Poly ε-caprolactone (PCL) is a well-known synthetic aliphatic polyester universally used for many applications, including biomedical and environmental ones. Unlike poly lactic acid (PLA), PCL has no chiral atoms, and it is impossible to play with the stereochemistry to modify its properties. To expand the range of applications for PCL, researchers have investigated the possibility of grafting polymer chains onto the PCL backbone. As the PCL backbone is not functionalized, it must be first functionalized in order to be able to graft reactive groups onto the PCL chain. These reactive groups will then allow the grafting of new reagents and especially new polymer chains. Grafting of polymer chains is mainly carried out by “grafting from” or “grafting onto” methods. In this review we describe the main structures of the graft copolymers produced, their different synthesis methods, and their main characteristics and applications, mainly in the biomedical field.

“…In the case of physical crosslinking, the following methods have been used: freeze-thawing (poly (vinyl alcohol) (PVA), PVA/chitosan); stereocomplex formation (poly(l-lactide)-poly(d-lactide)); ionic interaction (chitosan, alginates); H-bonding (hyaluronic acid); and maturation (heat-induced aggregation, hyaluronic acid) [16][17][18][19][20][21][22][23][24][25][26][27]. Meanwhile, chemically crosslinked hydrogels can be obtained using chemical or radiation grafting (poly (ε-caprolactone), poly (ethylene glycol), N-vinyl caprolactam, chitosan); radical polymerization (poly (ethylene glycol) methyl ether methacrylate); condensation or enzymatic reaction (B-cyclodextrin, chitosan); UV, microwave, gamma, or electron beam irradiation (poly (vinyl methyl ether), alginate/PVA, chitosan, polyethylene oxide (PEO), and poly (acrylic acid) (PAAc), polyvinylpyrrolidone (PVP)/carboxymethyl cellulose (CMC)) [16,[28][29][30][31][32][33][34][35][36][37]. The choice of the synthetic route for hydrogel preparation is significant because the type of crosslinking method used may affect the final properties [20].…”

Alginate Hydrogels with Aloe vera: The Effects of Reaction Temperature on Morphology and Thermal Properties

2022

View full text Add to dashboard Cite

In this study, we investigated the impact of reaction temperature on the physicochemical, structural, morphological, and thermal properties of sodium alginate/poly (vinyl alcohol)-based hydrogels, both in the pure form and with the addition of 20% (v/v) Aloe vera solution. The materials were prepared by chemical crosslinking at temperatures in the range of 65–75 °C. Poly (ethylene glycol) diacrylate was used as a crosslinking agent. The extent to which the crosslinking reaction proceeded was studied as a function of the reaction temperature, along with the thermal properties and morphology of the final materials. A measurement of gel fraction, in agreement with differential scanning calorimetry and Fourier transform infrared spectroscopy, showed that a higher temperature of reaction promoted the crosslinking reaction. On the basis of the aforementioned techniques, as well as by energy dispersive X-ray analysis under an electron microscope, it was also shown that the bioadditive Aloe vera promoted the crosslinking reaction.
