“…It is evident that the in-situ process introduced in this study results in a homogenous distribution of carbon particles throughout the PP matrix. As discussed in more detail by Akram et al., 21 the pyrolysis of CMC results in spherical carbon particles of 41 µm size.…”

“…The authors report in detail in a previous work 21 the decomposition behaviour of CMC, evidencing a minimum necessary temperature for degradation of 250 C, and a termination of the decomposition behaviour at 300 C, leaving, 50% ash content in the form of amorphous carbon. The maximum decomposition rate was observed at around 270 C.…”

“…On the other hand, a maximum processing temperature of 340 C, corresponding to the PP degradation temperature, should not be exceeded. Plotting the time needed for pyrolysis at various isothermal temperatures, examined in a previous study, 21 shows that an increase in temperature from 260 C to 270 C would help reduce the processing time by 9 min. A reduction of processing time is crucial for the protection of the matrix material from thermal degradation, by the influence of thermal exposure time.…”

An adequate dispersion of fine particles is essential for improved properties in particle-reinforced composites. State-of-the-art methods mainly rely on mechanical (shearing) dispersion methods that do not yield the requested homogeneity within the final composite. This leads to a deterioration and inhomogeneity of mechanical properties. Other non-conventional methods such as in-situ polymerisation or solution compounding are not yet applicable on an industrial scale. This study tackles these problems and provides a novel method for the fabrication of well-dispersed particle-reinforced polymer composites while making use of conventional machinery on the one hand and allowing industrial applicability on the other hand. The presented technique makes use of the pyrolysis of a low thermally stable polymer within a conventional melt compounding process to produce well dispersed carbon particles throughout a thermoplastic matrix in an in-situ process. For this purpose, Carboxymethylcellulose particles are used. The selection of decomposition parameters around the processing temperature of polypropylene yields well-dispersed carbon particles, as evidenced by scanning electron microscopy. This further interprets the resulting promising mechanical properties.

Triboelectric nanogenerators (TENGs) are an emerging technology capable of converting the ambient mechanical energy into electricity, promising for complete utilization of the distributed energy to improve the quality of human life. However, realizing material innovation for good trade‐off between the high triboelectric output and environment friendliness remains huge challenge, but it is of great importance for sustainable development of TENGs. Cellulose is a typical natural polymer that promises to address the challenge. Herein, the sustainable TENGs that originate from cellulose and potentially back to the natural world are focused on, realizing on‐spot TENGs. First, the sources, forms, morphologies, structures, and modifications of cellulose are systematically summarized, indicating the commercial and noncommercial cellulose materials’ potential for TENGs’ application. Second, the dominating additive properties of cellulose such as hydrophobicity, self‐cleaning, corrosion resistance, optical transparency, electrical conductivity, and degradability are introduced, which can effectively steer the development of TENGs. Thereafter, the TENGs with tailorable functions enabled by less‐refined cellulose and various physical/chemical modified cellulose are reviewed, as well as plants‐supported on‐spot TENGs with environment adaptivity and transient property, embracing a sustainable future of versatile cellulose to adapt the distributed network of multiscenario TENGs for energy management and information communication.

The growing potential of sustainable materials such as polyhydroxyalkanoates (PHAs), polylactic acid (PLA), alginate, carrageenan, and ulvan for bioplastics production presents an opportunity to promote a sustainable circular economy. This review investigates their properties, applications, and challenges. Bioplastics derived from algae offer an environmentally friendly alternative to petroleum‐based plastics, a shift of paramount importance to society due to the escalating environmental concerns associated with traditional plastics. The role of the internet‐of‐things (IoT) and machine learning in refining these bioplastics' production and development processes is emphasized. IoT monitors cultivation conditions, data collection, and process control for more sustainable production. Machine learning can enhance algae cultivation, increasing the supply of raw materials for algal bioplastics and improving their efficiency and output. The study results indicate the promise of algae‐based bioplastics, IoT, and machine learning in fostering a more environmentally sustainable future. By harnessing these advanced technologies, optimization of bioplastic production is possible, potentially revolutionizing the materials industry and addressing existing challenges toward achieving a sustainable circular economy.
