Supercritical CO2-assisted impregnation of LDPE/sepiolite nanocomposite films with insecticidal terpene ketones: Impregnation yield, crystallinity and mechanical properties assessment
(Elsevier Science, 2017-06)
In this contribution, supercritical CO2-assisted impregnation of LDPE/sepiolite nanocomposite films with two insecticidal terpene ketones (thymoquinone and R-(+)-pulegone) is investigated, as a strategy to enhance the ...
Eugenol-loaded LLDPE films with antioxidant activity by supercritical carbon dioxide impregnation
(Elsevier Science, 2016-05)
In this work, linear low density polyethylene (LLDPE) films were impregnated with eugenol using supercritical CO2 impregnation, as a strategy for obtaining a loaded material to be potentially applied in active food packaging. ...
Development of polycaprolactone scaffold with antibacterial activity by an integrated supercritical extraction and impregnation process
(Elsevier Science, 2013-03-23)
The present study is aimed to develop a process for production of functionalized scaffolds impregnated with natural compounds extracted from Patagonian Usnea lichen. A setup for an integrated supercritical CO2 extraction ...

Carvone-loaded LDPE films for active packaging: Effect of supercritical CO2-assisted impregnation on loading, mechanical and transport properties of the films
(Elsevier Science, 2018-03)
In this work, low density polyethylene (LDPE) films were loaded by scCO2-assisted impregnation with R-(−)-carvone, the main component of M. spicata and A. polystachya essential oils with antimicrobial and insecticidal ...
Supercritical carbon dioxide assisted impregnation of eugenol into polyamide fibers for application as a dental floss
(Elsevier B.V., 2019-07)
Supercritical CO2-assisted impregnation was applied to incorporate eugenol into polyamide fibers in order to develop a solvent-free material with antimicrobial properties to be potentially applied as dental floss. Impregnation ...
Active LDPE films loaded with biopesticides by supercritical CO2-assisted impregnation for stored grain protection
The aim of this contribution was to obtain bioactive materials for stored grain protection and food preservation, by incorporating a biopesticide (1-octen-3-ol) in polyethylene (LDPE) films using supercritical CO2–assisted ...
Mass transfer kinetics of CO2 and eugenol in the supercritical impregnation of polyamide fibers: Experimental data and modeling
(Elsevier Science, 2020-12)
In this work, mass transfer kinetics of CO2 and eugenol into polyamide 6 (PA6) fibers under supercritical conditions were investigated in the context of the development of a functional dental floss for dental care applications ...
Supercritical CO2 iof LDPE films with terpene ketones as biopesticides against corn weevil (Sitophilus zeamais)
(Elsevier Science, 2017-04)
In this work, the supercritical carbon dioxide impregnation of low density polyethylene (LDPE) films with a mixture of two terpenic ketones (thymoquinone and R-(+)-pulegone) with biopesticide activity is investigated, as ...
Study of chia oil microencapsulation in soy protein microparticles using supercritical CO2-assisted impregnation
Microencapsulation of chia oil in soy protein microparticles was achieved using supercritical CO2-assisted impregnation, an alternative green technology. The effect of the process variables on retention and encapsulation ...
