Development, Evaluation, and Characterization of a Novel Mucoadhesive Film Containing Pterodon pubescens Benth Ethanolic Extract for Dental Use

open access: yesJournal of Applied Polymer Science, EarlyView.
Pterodon pubescens Mucoadhesive Film for dental use. ABSTRACT Periodontal diseases involve infectious and inflammatory processes that affect oral tissues. Extracts from Pterodon pubescens Benth (sucupira) have demonstrated antinociceptive, anti‐inflammatory, anti‐edematogenic, and antiplatelet effects, highlighting their therapeutic potential for ...

Assessing the Biodegradability of 2‐Methylene‐1,3‐Dioxepane (MDO)‐Based Multicomponent Polymers Under Aerobic Composting Conditions

open access: yesJournal of Applied Polymer Science, EarlyView.
This study evaluates the biodegradability of multicomponent polymers incorporating 2‐methylene‐1,3‐dioxepane (MDO) under aerobic composting conditions. Increasing the amount of MDO and the addition of carboxylated cellulose nanocrystals (cCNCs) enhanced biodegradation.

Correlation Between Vinyl Content of Recycled HDPE and Polymer Degradation: An NMR Approach

open access: yesJournal of Applied Polymer Science, EarlyView.
The degradation behavior of high‐density polyethylene (HDPE) during recycling depends on its vinyl group content. This study shows that 1H NMR spectroscopy enables accurate assessment of vinyl groups unlike FTIR. Changes in melt flow and molecular weight with multiple processing are linked to vinyl content which could enable tailor‐made re‐additivation

Investigation of the Degradation Behavior of Polyurethane Film by Selected Bacteria and Their Influence on Thermal and Mechanical Properties

open access: yesJournal of Applied Polymer Science, EarlyView.
The cultivation of bacterial strains and their incubation in a minimal medium containing polyurethane as the carbon source, followed by analysis to investigate the microbial biodegradation of polyurethane film. ABSTRACT This study shows the potential of four bacterial strains, namely Anerinibacillus migulanus, Bacillus subtilis, Pseudomonas fluorescens,
