Thermo-mechanical characterization of PHB/PCL blend incorporated with carbon nanotubes

eXPRESS Polymer Letters
Polyhydroxybutyrate (PHB) is a polymer with great application potential; however, its brittleness and low mechanical strength restrict its use in many fields. This study investigated a strategy to overcome the mechanical limitations of PHB by blending it

Novel processing of polyhydroxybutyrate with micro- to nanofibrillated cellulose and effect of fiber morphology on crystallization behaviour of composites

eXPRESS Polymer Letters, 2020
In this work, the intrinsic drawbacks of polyhydroxybutyrate (PHB) such as slow crystallization rate, secondary crystallization and brittle nature were improved by blending with bio-based fillers, i.e. nanofibrillated/microfibrillated cellulose (NFC/MFC).

Recycled Cellulose‐Based Colorimetric Indicators for Non‐Contact Detection of Food Contamination

Advanced Sustainable Systems, Volume 10, Issue 4, April 2026.
Recycled cellulose acetate films, functionalized with red cabbage anthocyanins, combine antioxidant activity and pH‐responsive color changes for smart food packaging. They extend shelf life by preventing oxidation and enable non‐contact detection of bacterial contamination via VOC‐triggered color shifts.

Stimulus‐Induced Self‐Reinforcement in Supramolecular Bamboo Plastics toward Mechanical Robustness and Programmable Shapeability

Advanced Science, Volume 13, Issue 24, 27 April 2026.
A self‐reinforcement strategy is reported for the fabrication of bamboo plastics utilizing ethanol to induce the supramolecular network reconstruction of cellulose and polyacrylamide molecules. These bamboo plastics exhibit high mechanical strength, excellent thermal stability, resistance to low temperatures, and controllable shapeability.
