Special Issue Information

Dear Colleagues,

Low-dimensional carbon materials include zero-dimensional carbon quantum dots, fullerenes, one-dimensional carbon nanotubes, two-dimensional graphene and other related materials, which have unique optical, electrical, magnetic, thermal, mechanical properties and a large specific surface area. By compounding with polymers, the microstructure of the composites can be regulated, to obtain excellent performance with broad application prospects in the fields of flexible electronics, biomedicine, energy storage, electromagnetic shielding, water treatment, etc.

This Special Issue invites original research articles and critical reviews on the most recent advancements of low-dimensional carbon-based polymer composites. Potential topics include but are not limited to:

  • Polymer composites based on carbon quantum dots, fullerenes, carbon nanotubes, graphene, etc.;
  • Preparation and characterization of low-dimensional materials as polymer fillers;
  • Structures, properties and applications of low-dimensional carbon/polymer composites;
  • Design and functionalization of multidimensional and multi-scale composites.

Flexible wearable strain sensors based on laser-induced graphene (LIG) have attracted significant interest due to their simple preparation process, three-dimensional porous structure, excellent electromechanical characteristics, and remarkable mechanical robustness. In this study, we demonstrated that LIG with various defects could be prepared on the surface of polyimide (PI) film, patterned in a single step by adjusting the scanning speed while maintaining a constant laser power of 12.4 W, and subjected to two repeated scans under ambient air conditions. The results indicated that LIG produced at a scanning speed of 70 mm/s exhibited an obvious stacked honeycomb micropore structure, and the flexible strain sensor fabricated with this material demonstrated stable resistance. The sensor exhibited high sensitivity within a low strain range of 0.4–8.0%, with the gauge factor (GF) reaching 107.8. The sensor demonstrated excellent stability and repeatable response at a strain of 2% after approximately 1000 repetitions. The flexible wearable LIG-based sensor with a serpentine bending structure could be used to detect various physiological signals, including pulse, finger bending, back of the hand relaxation and gripping, blinking eyes, smiling, drinking water, and speaking. The results of this study may serve as a reference for future applications in health monitoring, medical rehabilitation, and human–computer interactions. Full article

The photocatalytic degradation of organic dyes in waste water using carbon quantum dots (CQDs) remains a hot topic due to the importance of environmental protection. However, identifying suitable carbon resources and successful surface modification are still challenging. Herein, the hydrothermal method and surface modification of ammonia and thionyl chloride were applied to synthesize CQDs with different surface groups using PEO106PPO70PEO106 (Pluronic F127) as a carbon source. The average particle size of the as-prepared CQDs was in the range of 2.3–3.5 nm. The unmodified CQDs had the highest relative photoluminescence intensity, while all as-prepared CQDs exhibited abnormal photoluminescence located outside the scope of the visible spectrum. Interestingly, CQDs modified with ammonia achieved a degradation rate of 99.13% (15 d) for 50 mg/L indigo carmine solution, while CQDs modified with thionyl chloride reached a degradation rate of 97.59% (15 d) for light green SF yellowish solution. Therefore, in this work, two typical organic dyes can be effectively photocatalytically degraded by as-prepared CQDs, with suitable surface modification. Full article
