Ultrasound morphology of polycaprolactone filler
Nowadays, cosmetic fillers are widely used and the reports of complications are rising. Therefore, the possibility to detect and identify noninvasively new fillers can provide a potent tool for managing complications. The ...
Chemoenzymatic synthesis of a novel N-2-hydroxyethyl)-beta-peptoid oligomer and application to porous polycaprolactone films
Poly[N-(2-hydroxyethyl)-beta-propylamide] oligomer is syntehsized using a simple enzymatic procedure involving Candida antarctica lipase B. This novel compound is obtained by a green and chemoselective method from economic ...
ADSORPTION OF MULTIWALLED CARBON NANOTUBES ON ELECTROSPUN POLYCAPROLACTON NANOFIBERS
(Sociedad Chilena de Química, 2009)
Morphological, mechanical properties and biodegradability of biocomposite thermoplastic starch and polycaprolactone reinforced with sisal fibers
(Sage Publications Ltd, 2012-04-01)
The incorporation of fibers as reinforcements in polymer composites has increased due to their renewability, low cost and biodegradability. In this study, sisal fibers were added to a polymer matrix of thermoplastic starch ...
Sorption and diffusion of compressed carbon dioxide in polycaprolactone for the development of porous scaffolds
In this work different phenomena related to sorption of carbon dioxide in polycaprolactone (PCL) have been investigated systematically. The use of compressed carbon dioxide is discussed for obtaining porous scaffolds from ...
Processing and characterization of thermoplastic starch/polycaprolactone/compatibilizer ternary blends for packaging applications
Thermoplastic starch (TPS)/polycaprolactone(PCL) blends were obtained by melt mixing. First, thebest formulation of thermoplastic starch (starch, plasticizerand additives) was studied. The obtained filmswere characterized ...
Synthesis of polycaprolactone using free/supported enzymatic and non-enzymatic catalysts
(Wiley VCH Verlag, 2004-12)
Polymerization of caprolactone using lipases from Candida antarctica B, Rhizomucor meihei, Candida rugosa, and Pseudomonas fluorescens is highly effective, with 97% conversion into polycaprolactone. Poly(propylene)-supported ...
Optically transparent membrane based on bacterial cellulose/ polycaprolactone
Optically transparent membranes from bacterial cellulose (BC)/polycaprolactone (PCL) have been prepared by impregnation of PCL acetone solution into dried BC membranes. UV-Vis measurements showed an increase on transparency ...
