Special Issue Information

Dear Colleagues,

Polymeric materials—commonly not biodegradable—remain the workhorse materials in daily life. There is (finally, relatively slow) movement in the field towards advanced sustainable polymer materials that can be easily biodegraded or can be repurposed. In the ambition of achieving carbon neutrality, everyone on the Earth needs to take actions to make contributions in order to make the Earth a better home. To echo this call, various pioneering works have been reported on sustainable polymers and the corresponding processing technology, including, but not limited to, self-healing or recyclable materials, naturally sourced materials (lignin, cellulose, soybean oil, etc.), and stimuli-reponsive smart materials for energy saving. However, for many reasons, progress in finding practical routes are still highly demanded with repect to low cost, clean process, and low energy consumption.

This Special Issue covers various subjects related to technologies for advanced sustainable polymeric materials. Three areas for polymer researchers to address in the field of sustainable polymeric materials include, but are not limited to, the following: to lower carbon emission and engery consumption of producing polymeric materials; to realize a circular economy of polymeric products; and to reduce usage and generation of toxic substances before, during, and after producing polymeric materials.

Original works within the scope are invited and literature reviews are also highly appreciated.

This research article elaborates on the conceptual design development of a sustainable bionanocomposite bracket for bracing installation in composite cross arm structures. The product design development employed the hybrid techniques of the theory of inventive problem solving (TRIZ), morphological chart, and analytic network process (ANP) methods. The current bracket design in the braced composite cross arm is composed of heavy and easy-to-rust steel material. Therefore, this research aims to develop a new bionanocomposite bracket design to replace the heavy and easy-to-rust steel bracket. This research also aims to implement a concurrent engineering approach for the conceptual design of bionanocomposite bracket installation to enhance the overall insulation performance. A preliminary process was implemented, which covered the relationship between the current problem of the design and design planning to build a proper direction to create a new design product using TRIZ. Later, the TRIZ inventive solution was selected based on the engineering contradiction matrix with specific design strategies. From the design strategies, the results were refined in a morphological chart to form several conceptual designs to select the ANP technique to systematically develop the final conceptual design of the bionanocomposite bracket for the cross arm component. The outcomes showed that Concept Design 1 scored the highest and ranked first among the four proposed designs. The challenges of the bionanocomposite bracket design for cross arm structures and the improvement criteria in concurrent engineering are also presented. Full article

While the beneficial physical properties of silicone polymers are exploited in many sustainable applications, the high energy requirement for their synthesis compromises to a degree their sustainability. We report a strategy to mitigate this issue by filling the silicone with inexpensive and renewable starch. Elastomeric materials with covalently grafted starch, utilizing anhydride-modified silicones, permits loading of up to about 75% starch while maintaining many of the properties of the silicone. Alternatively, 50 wt.% starch-filled silicone foams can be prepared simply by mixing powdered starch with a mixture of HSi-functional silicone fluids in the presence of B(C6F5)3. The physical properties of the resulting foams are determined by the quantity of SiH, which controls the final density of the foams (ranging from 0.258–0.875 g mL−1), their Young’s modulus, and their degree of elasticity; both rigid and flexible foams were prepared. Materials with a high natural and renewable material content better adhere to green chemistry principle 7, should enhance the ease of degradation at end of life, and augment the sustainability of these silicone composites.

In this paper, a new type of water pressure and air pressure composite slurry is proposed to ensure the safety of spraying. Firstly, the air tightness, bending resistance and viscosity of the spraying material were measured in the laboratory. Secondly, the two-fluid VOF model was used to analyze the influence laws of the spraying process, the spraying area formed on the wall, the thickness of the spraying layer and the pressure at the nozzle (or initial flow rate), the spraying distance, the spraying time, and the spraying direction. The research shows that (1) the new composite slurry spraying material made of clay:cement:additive:engineering fiber = 84:14:1.85:0.15 has suitable sealing and bending resistance and adhesion. (2) The smaller the spraying distance is, the larger the spraying area formed on the side wall in a short time, and the shape is regular, but the spraying area is relatively small. The spraying area increases with the increase in spraying distance, and the slurry thickness becomes thinner with the increase in spraying distance. (3) When the initial spraying speed is high, the shape of the spraying area is regular, the spraying thickness is large and the uniformity is suitable, but the shape and uniformity of the spraying area are related to the time when the slurry reaches the side wall. The longer the time when the slurry reaches the side wall, the greater the influence of gravity and surrounding fluid, and the more changes along the process. (4) When the spraying surface is at the top, the spraying process is significantly affected by gravity, and discontinuous spraying areas will be formed on the top surface. Especially when the initial spraying speed is low, the amount of slurry reaching the top surface fluctuates due to rebound and increases with the increase in the initial spraying speed. Full article

The accumulation of plastic wastes is one of the most widely spread problems affecting the environment. The reality that plastics can be made from renewable resources and degrade naturally has prompted academics to think outside the box to develop “better for the environment” items. In this paper, a bibliometric analysis of the scholarly publications related to bio-based plastics within the last 20 years is presented. Annual progression, geographic and research area distribution, and keyword co-occurrence were all examined. Six distinct clusters emerged from keyword analysis, which were further categorized into three directions: production to marketing; impact on the environment, economy, and society; and end-of-life (EoL) options. The major focus was on how to counter the weaknesses and challenges of bio-based plastics and take opportunities using the inherent advantages of bio-based plastics. Comprehensive studies regarding the impact of bio-based plastics on the environment, economy and social sustainability are still deficient. Although there are many promising innovations in this area, most of them are at the research stage. The benefits of bio-based plastics and better EoL options can be enjoyed only after increased production. Full article
