“…[2][3][4] As adhesives, EVA copolymers are often used in combination with different types of materials like wood, rubber, metals, glass and polymers. 5,6 EVA properties depend on the content of each comonomer. Crystallization and melting characteristics of EVA are very sensitive to the VA content.…”

“…7 The melting temperature and degree of crystallinity decreases with an increase of vinyl acetate groups, but the glass transition temperature (T g ) increases with the increase of vinyl acetate content. [5][6][7][8] Presence of ethylene segments in EVA molecules provides characteristic to "plasticized" and increases the activity. 9 The mechanical properties of the EVA as matrix are inferior compared to the fibers like ultra-high molecular weight polyethylene (UHWMPE) and they can be improved using inorganic fillers having a different morphology.…”

Processing of hybrid composites represents a challenge for engineers where the aim is to establish compatibility among several materials. The aim of this study is to evaluate the effects of different size and morphology of alumina fillers on the mechanical and thermal properties of the composite fibers based on ultra-high molecular weight polyethylene fibers (UHMWPE).These fibers have an outstanding elastic modulus and they are compatible with nonpolar sequences of the poly(ethylene-co-vinyl acetate) (EVA) matrix. Compared to the fibers, inferior mechanical properties of the matrix can be improved using alumina particles. Commercial Al 2 O 3 nanoparticles, commercial whiskers and synthesized particles of Al 2 O 3 doped with iron oxide, incorporated in different weight percent were used as fillers. The UHMWPE fibers were impregnated using the solution of EVA in toluene with dispersed particles. FT-IR and FE-SEM were used for structural examination. Tensile testing revealed increasing of modulus of elasticity and strengths of obtained hybrid composite fibers. Thermal gravimetry showed improved thermal stability up to 350°C of the hybrid composite fibers with alumina particles doped with iron oxide. Results of tested samples showed that the best mechanical properties were for hybrid composite fibers with 1 wt.% of iron doped alumina filler.

“…Depending on the percent of VA, EVA may take different physical properties; the more VA, the higher polarity, adhesion, impact resistance, flexibility, and compatibility with other polymers. However, when increasing VA, a decrease in crystallinity, stiffness, softening, and melting point is also observed, as exemplified in Table 1 and Table 2 [ 20 , 21 ]. The probability of modifying most of the properties of EVA regulating VA content offers a broad range of possibilities in the design of new materials.…”

Polymeric Implants for the Treatment of Intraocular Eye Diseases: Trends in Biodegradable and Non-Biodegradable Materials

et al. 2021

Intraocular/Intravitreal implants constitute a relatively new method to treat eye diseases successfully due to the possibility of releasing drugs in a controlled and prolonged way. This particularity has made this kind of method preferred over other methods such as intravitreal injections or eye drops. However, there are some risks and complications associated with the use of eye implants, the body response being the most important. Therefore, material selection is a crucial factor to be considered for patient care since implant acceptance is closely related to the physical and chemical properties of the material from which the device is made. In this regard, there are two major categories of materials used in the development of eye implants: non-biodegradables and biodegradables. Although non-biodegradable implants are able to work as drug reservoirs, their surgical requirements make them uncomfortable and invasive for the patient and may put the eyeball at risk. Therefore, it would be expected that the human body responds better when treated with biodegradable implants due to their inherent nature and fewer surgical concerns. Thus, this review provides a summary and discussion of the most common non-biodegradable and biodegradable materials employed for the development of experimental and commercially available ocular delivery implants.

Cilj ovoga rada je ispitivanje mehaničkih svojstava hibridnih kompozita sa polimernom matricom, matrice kopolimera etilena i vinil-acetata (EVA), polietilenskih vlakana ultra visoke molarne mase (UHMWPE) i čestica na bazi aluminijum oksida. Komercijalne nanočestice aluminijum oksida i čestice aluminijum oksida dobijene sol-gel tehnikom korišćene su kao punioci u udelu od 1, 3 i 5 mas. %. Infracrvena spektroskopija sa Furijeovom transformacijom (FTIR) i skenirajuća elektronska mikroskopija (SEM) korišćene su za ispitivanje hemijske strukture i mikrostrukture hibridnih kompozita, datim redom. Ispitivanje na zatezanje pokazalo je povećanje modula elastičnosti i zatezne čvrstoće dobijenih hibridnih kompozita. Rezultati ispitivanja uzoraka pokazali su da najbolja mehanička svojstva i žilavost materijala pokazuje hibridni kompoziti sa 1 mas. % mikronskihčestica aluminijum oksida.
