“…Figure 8(d) is the crystallinity obtained from the analysis of DSC results. All of SCF, GO, and MAPP can improve the crystallinity of the PP composites, 19 thereby increasing the proportion of crystalline regions in the PP composite. As shown in Figure 7(d), a higher proportion of crystalline regions under the same material volume can achieve better cryogenic dimensional stability.…”

“…However, due to the inert surface of SCF and the nonpolar nature of PP, there is weak interface compatibility between SCF and PP, which limits the performance of PP composites to a certain extent. Fortunately, maleic anhydride grafted PP (MAPP) as compatibilizer can improve the compatibility between the filler and the resin matrix significantly 19 . In addition, the unique two‐dimensional structure and excellent comprehensive properties of graphene oxide (GO) have also received great attention in the field of modifying fibers in recent years 20,21 .…”

In order to expand the application of polypropylene (PP) composites in cryogenic environment, short carbon fiber (SCF) was used as the reinforcing phase and the surface of it was modified by graphene oxide (GO), and the maleic anhydride grafted PP (MAPP) was also used to enhance the interface compatibility between the fiber and the matrix. The effects of the GO‐modified SCF and the MAPP on the impact properties and dimensional stability of PP composites at cryogenic temperature (CT) (− 196°C) were investigated by systematic analysis of the interfacial properties and microstructure of the composites. The results show that the impact strength of the PP composites was effectively increased by 106.7% (CT) and 170.7% (room temperature), respectively, compared to pure PP. In addition, the transverse and longitudinal shrinkage of PP composites can be reduced to only 0.15% and 0.1%, respectively. The cryogenic impact strength and dimensional stability of PP composites has been greatly improved, which makes PP composites in the application under cryogenic environment is more promising.

“…For fabrication of plastics, CGT has been previously combined with different synthetic polymers such as poly(vinyl alcohol) (PVA) [12,28], polypropylene [29], and low-density polyethylene (LDPE) [30]. However, these studies either have used biodegradable polymers through solution casting in small-scale, or industrially more viable method, i.e., extrusion, though with non-biodegradable polymers.…”

Sustainable Cotton Gin Waste/Polycaprolactone Bio-Plastic with Adjustable Biodegradation Rate: Scale-Up Production through Compression Moulding

et al. 2023

Cotton gin trash (CGT), a lignocellulosic waste generated during cotton fibre processing, has recently received significant attention for production of composite bio-plastics. However, earlier studies were limited to either with biodegradable polymers, through small-scale solution-casting method, or using industrially adaptable extrusion route, but with non-biodegradable polymers. In this study, a scale-up production of completely biodegradable CGT composite plastic film with adjustable biodegradation rate is proposed. First using a twin screw extruder, the prepared CGT powder was combined with polycaprolactone (PCL) to form pellets, and then using the compressing moulding, the pellets were transformed into bio-plastic composite films. Hydrophilic polyethylene glycol (PEG) was used as a plasticiser in the mixture and its impact on the biodegradation rate was analysed. The morphology of CGT bio-plastic composite films showed even distribution of CGT powder within the PCL matrix. The CGT incorporation improved the UV resistance, thermal stability, and Young’s modulus of PCL material. Further, the flexibility and mixing properties of the composites were improved by PEG. Overall, this study demonstrated a sustainable production method of CGT bio-plastic films using the whole CGT and without any waste residue produced, where the degradation of the produced composite films can be adjusted to minimise the environmental impact.

“…5,6 Another method of utilizing cotton gin waste is as cattle feed, 7 but its low protein content poses limitations. 8 Recently, considerable efforts have been made to explore the potential of cotton gin waste as a valuable source for the production of new materials, including films, 9,10 composites, 11,12 packaging, 13 particleboard, 14 adsorbent materials, 15 and nanocellulose. 1 In this study, we aim to demonstrate the remarkable capability of cotton gin waste in the synthesis and hosting of silver nanoparticles.…”

Cotton gin waste presents a significant challenge in the cotton ginning industry due to its abundant generation and limited disposal options. In this study, we explored the potential of cotton gin waste as a naturally occurring source material that can synthesize and host silver nanoparticles. The noncellulosic constituents of cotton gin waste served as effective reducing agents, facilitating the conversion of silver ions into silver atoms, while its porous structure acted as a microreactor, enabling controlled particle growth. A simple heat treatment of cotton gin waste powder in an aqueous silver precursor solution actualized the in situ synthesis of silver nanoparticles, without the need for additional chemical agents. Remarkably, a high concentration of silver nanoparticles (14.7%) with an average diameter of approximately 27 nm was produced throughout the entire volume of cotton gin waste. Electron microscopic images of cross-sectioned cotton gin waste confirm the internal formation of nanoparticles. Rietveld refinement analysis of X-ray diffraction patterns showed that the majority of the nanoparticles possess a cubic silver crystal structure. By leveraging the well-known biocidal properties of silver nanoparticles, the resulting silver nanoparticle-filled cotton gin waste holds promise for novel antimicrobial and antifungal material applications.
