Surfactant‐Enhanced Electrospun Nanofiber Filters for Efficient Viral and Bacterial Inactivation

open access: yesJournal of Applied Polymer Science, EarlyView.
In this work, electrospun polyacrylonitrile (PAN) nanofibrous filters functionalized with surfactants (CTAB, CPC, and SDS) were developed for air filtration applications. The PAN nanofiber mats enable efficient particulate matter capture while simultaneously providing antimicrobial and antiviral activity against bacteria (E. coli and S.

Polyethylene–Cellulose Composites From Cellulose Xanthate Solutions

open access: yesJournal of Applied Polymer Science, EarlyView.
An approach for fabricating cellulose/LDPE composites through cellulose dissolution, LDPE dispersion, and subsequent hot‐pressing. ABSTRACT This study reports a processing route for fabricating cellulose/LDPE composites involving the dispersion of polyethylene powder in a cellulose solution, followed by regeneration to form a continuous cellulose ...

Improving Oxygen Barrier Performance of Polylactide Film by Using Bleached and Unbleached Nanocellulose From Grape Pomace

open access: yesJournal of Applied Polymer Science, EarlyView.
Bleached and unbleached nanocelluloses were produced from the exhausted grape pomace and applied as coatings on PLA substrates for sustainable food packaging. Unbleached nanocelluloses were more hydrophobic and amorphous than bleached ones. The resulting bio‐based bleached nanocellulose‐coated PLA films showed a 68% reduction in O2 permeability ...

Development and Characterization of Cellulose Films Incorporating Vitamin A and E‐Loaded Liposomes

open access: yesJournal of Applied Polymer Science, EarlyView.
Liposome‐cellulose films deliver UV‐light shielding, wetting, and high rigidity for green tattoo aftercare. ABSTRACT This study introduces cellulose films enriched with vitamin A/E liposomes as sustainable, bioactive dressings for tattoo aftercare. Morphological analysis showed a smoother, more continuous microtexture than the neat cellulose films ...

Tailored Dual Responsive Hybrid Gelatin Methacryloyl/Poly[2‐(Dimethylamino)Ethyl Methacrylate] Hydrogels for Efficient Ibuprofen Release in Topical Applications

open access: yesJournal of Applied Polymer Science, EarlyView.
GelMA/DMAEMA hybrid hydrogels for release of ibuprofen. ABSTRACT In this study, biocompatible hydrogels intended for topical delivery of ibuprofen were synthesized from gelatin methacryloyl (GelMA) and 2‐(dimethylamino)ethyl methacrylate (DMAEMA) by varying their proportions. The impact of different GelMA and DMAEMA ratios was comprehensively evaluated

Effect of SSZ‐13 Zeolite Loading and Synthesis Time on the CO2/N2 Separation Performance of PDMS Mixed Matrix Membranes

open access: yesJournal of Applied Polymer Science, EarlyView.
Advantages of MMMs and the Robeson plot detailing improved performance of the 4d05% membrane. ABSTRACT Mixed matrix membranes were produced by incorporation of SSZ‐13 zeolites into polydimethylsiloxane (PDMS) to assess the effect of filler properties and concentration on the CO2/N2 separation efficiency compared to pure PDMS membranes.

Investigation of the Optical and Morphological Properties of PS/POMA Blends Hybridized With Erbium Oxide (Er2O3)

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT Polymeric blends (PB) represent a rapid and cost‐effective strategy for the development of materials with tailored properties. In this study, blends of polystyrene (PS) and poly(o‐methoxyaniline) (POMA) containing 7.5 wt/wt% of POMA were prepared and hybridized with erbium oxide (Er2O3) at concentrations of 0.5, 1.0, and 3.0 wt/wt%.

Engineering Electrospun PCL/PEO Membranes With ECM‐Like Architecture and Tunable Hydrophilicity as Functional Wound Dressings

open access: yesJournal of Applied Polymer Science, EarlyView.
Schematic illustration of the production of PCL/PEO electrospun membranes and their morphological, physical, and biological characterization. ABSTRACT Skin injuries resulting from trauma, burns, or chronic conditions such as diabetes often require advanced medical interventions, as conventional dressings provide only passive protection with limited ...

DNA metabarcoding reveals greater plant diversity than morphological seed analysis of bird feces

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Fruit‐eating birds drive seed dispersal in recovering tropical ecosystems, shaping forest regeneration. Molecular techniques, such as DNA metabarcoding, enable diet analysis from feces and can provide complementary frugivory data where dispersal is infrequent, as well as aid in seed identification in hyper‐diverse regions lacking ...
