Production of Elastomeric Composites With Different Methods of Incorporating of Graphene Nanoplatelets Into SBR Latex

Journal of Applied Polymer Science, EarlyView.
This study explores scalable methods of incorporating graphene nanoplatelets into SBR latex with or without a surfactant, using either powder or a masterbatch. Results show that combining a masterbatch with the surfactant DTAB improves vulcanization speed, mechanical strength, hardness, thermal conductivity, and resistance to aging.

Polylimonene Improves the In Vivo Wound Healing Performance of Sodium Alginate‐Based Hydrogels

Journal of Applied Polymer Science, EarlyView.
An oligomer derived from orange peel essential oil incorporated into an alginate hydrogel was shown to be biocompatible and to exhibit a high capacity for in vivo incisional wound healing, as confirmed by experimental assays and mathematical models fitted to the data describing wound area reduction as a function of the dressing‐tissue contact time ...

Polymer‐Crosslinking System‐Filler Interactions in Polychloroprene Adhesives: Experimental and Molecular Modeling Insights

Journal of Applied Polymer Science, EarlyView.
The use of polychloroprene is common in elastomeric adhesives. This study highlights the possible substitution of zinc oxide curing systems to a less hazardous metal complex, also evaluating the changes that higher surface area fillers can bring to the adhesive.

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

Journal 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

Journal 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

Journal 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 ...
