Role of Inorganic Fillers on the Physical Aging and Toughness Loss of PLLA/BaSO4 Composites
(ACS, 2023-11)
The addition of inorganic fillers has been reported to increase the toughness of poly(l-lactide) (PLLA), but the effect of physical aging in such composites has been neglected. The present work discusses the effect of the ...
Amorphous solid dispersions in Poly(ε-caprolactone)/Xanthohumol bioactive blends: physicochemical and mechanical characterization.
(Royal Society of Chemistry, 2021-04-26)
This paper reports the obtention of amorphous solid dispersions (ASDs) of
Xanthohumol (XH) into PCL containing up to 50 wt% of the bioactive compound in
amorphous form thanks to the advantageous specific interactions ...
Miscibility, interactions and antimicrobial activity of poly(ε-caprolactone)/ chloramphenicol blends
(Elsevier, 2018-03-13)
Poly(ε-caprolactone) (PCL) has been blended with Chloramphenicol (CAM), a well-known bacteriostatic antibiotic, in order to obtain new biomaterials with antibacterial properties. The resulting samples have been thoroughly ...
Morphology and Mechanical Properties of Poly(ethylene brassylate)/Cellulose Nanocrystal composites.
(Elsevier, 2019-06-01)
Poly(ethylene brassylate), a novel inexpensive biodegradable polyester, has been
reinforced with cellulose nanocrystals (CNCs) with the aim of improving its thermal
stability and mechanical properties. The composites ...
The conformation of chloramphenicol in the ordered and disordered phases
(Elsevier, 2019-03-15)
The conformational behavior of chloramphenicol (CHL) in the solid, liquid and
vapor phases is revisited here by means of FTIR spectroscopy and QM methods. In the
crystalline phase, both the IR analysis and QM computations ...
Nanostructured scaffolds based on bioresorbable polymers and graphene oxide induce the aligned migration and accelerate the neuronal differentiation of neural stem cells
(Elsevier, 2021-01-31)
Within the field of neural tissue engineering, there is a huge need for the development of materials that promote the adhesion, aligned migration and differentiation of stem cells into neuronal and supportive glial cells. ...
Lactide-caprolactone copolymers with tuneable barrier properties for packaging applications
(Elsevier, 2020-06-07)
Lactide-caprolactone copolymers have been synthetized employing two metallic catalysts, Ph3Bi and SnOct2. The analysis of the microstructure by NMR reveals that gradient like copolymers are obtained with SnOct2 catalyst, ...
Influence of the rigid amorphous fraction and crystallinity on polylactides transport properties
(ACS, 2018-05-15)
The effect of the crystallinity and polymorphism of PLLA and PDLA-PLLA 50:50 blends on the free volume and transport properties have been studied. In the case of PDLA-PLLA 50:50 the increase on crystallinity promotes a ...
Tributyl citrate as an effective plasticizer for biodegradable polymers: effect of the plasticizer on the free volume, transport and mechanical properties
(Society of Chemical Industry. Wiley, 2018-06-16)
The effectiveness of tributyl citrate (TbC) as plasticizer for polylactide (PLLA) and poly(hydroxybutyrate) (PHB) was analyzed in order to improve the ductility of these polymers and make them good candidates for food ...
