A comparative study on Poly(ε-caprolactone) film degradation at extreme pH values

Sailema-Palate, G. Patricia; Vidaurre Garayo, Ana Jesús; Campillo Fernández, Alberto José; Castilla Cortázar, María Isabel Cecilia (Elsevier, 2016-08)

The present paper studies the effect of pH on hydrolytic degradation of Poly(ε-aprolactone) (PCL) Degradation of the films was performed at 37 C in 2.5 M NaOH solution (pH 13) and 2.5 M HCl solution (pH 1). Weight ...
Disintegration in compost conditions and water uptake of green composites from poly(lactic acid) and hazelnut shell flour

Balart, J.F.; Montanes, Nestor; Fombuena, Vicent; Boronat, Teodomiro; Sanchez-Nacher, Lourdes (Springer-Verlag, 2018)

[EN] Green composites of poly(lactic acid)-PLA and hazelnut shell flour (HSF) with and without epoxidized linseed oil (ELO) as plasticizer/compatibilizer were subjected to different aging conditions such as water uptake ...
Hydrolytic degradation of PLLA/PCL microporous membranes prepared by freeze extraction

Gaona, Luis Andrés; Gómez Ribelles, José Luís; Perilla, Jairo Ernesto; Lebourg, Myriam Madeleine (Elsevier, 2012-09)

Poly(L-lactic acid) Poly(e-caprolactone) blends (PLLA/PCL) porous membranes were prepared by freeze extraction (a modification of freeze drying) with ratios 100/0, 80/20, 60/40, 40/60, 20/80, 0/100 in weight. Degradation ...
Poly(epsilon-caprolactone)/Graphene oxide composite systems: a comparative study on hydrolytic degradation at extreme pH values

CAMPILLO FERNANDEZ, ALBERTO JOSE; González-Reed, Pablo; Vidaurre, Ana; Castilla Cortázar, María Isabel Cecilia (American Scientific Publishers, 2020-06)

[EN] Polycaprolactone/Graphene oxide (PCL/GO) composites are shown to be promising substrates for tissue engineering as their degradation behavior is a key aspect in this type of application. The present paper studies the ...
Study of degradation of a new PLA braided biomnaterial in buffer phosphate saline, basic and acid media, intended for the regeneration of tendons and ligaments

Araque Monrós, María Carmen; Vidaurre, Ana; Gil Santos, Luis; Gironés Bernabé, Sagrario; Monleón Pradas, Manuel; Más Estellés, Jorge (Elsevier, 2013-09)

The purpose of this study was to evaluate the effects of hydrolytic degradation on the properties of a PLA hollow braid designed as a new concept of biodegradable prosthesis for the regeneration of tendons and ligaments. ...
