“…1-2, is pivotal in the bioplastic industry [1][2][3][4][5]. PLA has a limited crystallization rate, making it brittle and modest amounts of ductility, making it less than ideal for use in applications that need durability or engineering [6][7][8][9][10]. Prior to the last decade, PLA was only used in specialized biomedical applications such as resorbable sutures [11][12].…”

This review focuses on the modification of the inherent brittleness of biodegradable poly(lactic acid) (PLA) to increase its toughness, as well as recent advances in this field. The most often utilized toughening methods are melt blending, plasticization, and rubber toughening. The process of selecting a toughening scheme is still difficult, although it directly affects the blend's mechanical properties. There has been a lot of development, but there is still a long way to go before we get easily processable, totally bio-based, 100% biodegradable PLA. The blends of PLA with other polymers, such as plasticizers or rubber, are often incompatible with one another, which causes the blend's individual components to behave in a manner consistent with phase separation. Polymer blending has been shown to be particularly effective in attaining high-impact strength. This review addresses the recent progress in improving the toughened PLA to gain properties necessary for the material's future engineering applications. As 3D and 4D printing becomes more accessible, PLA characteristics may be modified and treated utilizing more sophisticated production techniques.

“…En la actualidad se pueden utilizar diversos métodos para la recuperación de neumáticos y la destrucción de sus componentes peligrosos. Los esfuerzos de la comunidad científica para encontrar formas de reducir los residuos de neumáticos han llevado a una intensa investigación sobre el caucho que incluye la posibilidad de aplicarlo en el relleno de concreto en vulcanizados de caucho natural y mezclas con polímeros (Colom et al, 2007;Manchón et al, 2004), también se ha utilizado caucho de llantas en desuso para intentar mejorar propiedades térmicas y mecánicas de biopolímeros como el ácido poliláctico con grafeno como microrelleno (Bijarimi et al, 2021), para incrementar la resistividad térmica, la absorción acústica y la amortiguación de vibraciones en compuestos de concreto (Bala y Gupta, 2021) y en la elaboración de materiales para el aislamiento térmico (Hittini et al, 2021). La superficie de láminas elaboradas a partir de llantas usadas se puede modificar a través de tratamientos como lo es el químico, la polimerización por injerto, modificación por radiación y modificación con gas (Romero et al, 2005;García et al, 2010).…”

En el presente estudio se examina el procedimiento de adhesión de láminas elaboradas con caucho de llantas desechadas usando el adhesivo poliuretano (PU). Adicionalmente, se evalúa la aplicación de una capa de elastómero sobre la superficie. Se elaboraron probetas para realizar tratamientos superficiales con ácido tricloroisocianúrico y permanganato de potasio. Se usaron tres promotores de adhesión: 1) diisocianato de tolueno, 2) 3-Aminopropiltrietoxisilano y 3) viniltrimetoxisilano. Las probetas se adhirieron y fueron sometidas a ensayos de tracción al pelado para determinar cuál es el mejor procedimiento de unión. Se realizaron pruebas de adhesión y análisis de caracterización con espectrometría infrarroja con transformada de Fourier, microscopía electrónica de barrido y energía dispersiva de rayos X. El mejor resultado se obtiene tratando la superficie con ácido tricloroisocianúrico. Se concluye que este tratamiento resulta efectivo para incrementar los valores de adherencia, tanto entre láminas unidas mediante PU como entre láminas y recubrimiento elastómerico.

Poly(lactic acid) (PLA) is a biodegradable polymer with limited application because of its intrinsic brittleness, low toughness, and low elongation at break. Melt blends were prepared by mixing a natural rubber (NR, poly(1,4‐cis‐isoprene) in the form of liquid NR (LNR), liquid‐epoxidized NR (LENR), and polypropylene (PP) in the PLA matrix. Four blend systems were designed and prepared, i.e., PLA–PP, PLA–PP–LNR, and PLA–LNR or PLA–LENR. The composition of PP in the blend was fixed at 10 % PLAPP (90/10). Results showed that PLA–PP mixed with LNR improved impact and elongation at break. The binary blend of PLA–LNR (90/10) significantly enhanced impact strength and elongation at break properties. In contrast, the binary blends of PLA–LENR (90/10) showed a lower value of elongation at break (9.5 % vs. 37.3%) and impact strength (4.56 kJ m−2 vs. 6.44 kJ m−2). The melting temperature (Tm) and the glass transition temperature (Tg) were measured by differential scanning calorimetry, which recorded slight changes in the glass temperatures and melting temperatures. Scanning electron microscopy images of the tensile fracture of the PLA–LNR (90/10) blend showed the presence of large fibrils associated with the ductile failure related to neat PLA. Finally, the fracture toughness (KIC) of PLA–LNR (90/10) showed an increase of 39 % over neat PLA (2.94 MPa.m1/2 vs. 4.08 MPa.m1/2).
