Mechanically durable green aerogel composite based on agricultural lignocellulosic residue for organic liquids/oil sorption

During the transportation of oil, various oil‐spill incidents are reported. The utilization of oil sorbents for the treatment of oil spills is a promising approach among the all‐existing solutions. Nonbiodegradability and non‐renewability are the two major issues in the case of synthetic oil sorbents. In this review, the use of biodegradable polymers for oil‐spill cleanup is highlighted. In each section, the biodegradable materials and modifiers used, the method applied for a modification, the contact angle after modification, sorption capacities, and the reusability of developed biodegradable sorbents are extensively discussed. Mechanisms of biodegradation of biopolymers are also discussed. The manuscript also incorporates the recent developments in the fabrications of advanced sorbents with sustainable approaches along with challenges associated with current sorbents and future prospects.

“…Somehow the usage of plant-based biopolymers is very limited in the case of oxygen scavenging packaging, although they have been used in ethylene scavenging, antioxidant, antimicrobial, optical materials, oil spill management, reinforcement, and thermal insulation. ,− In our earlier research, we established natural rubber latex as an effective oxygen scavenger, more than 2000 plant species in nature use a biosynthetic process to make rubber latex . On the other hand, β-myrcene has structural similarities to natural rubber latex, which paved the way to explore it as an active packaging material.…”

Food scarcity and safety are the utmost considerable issues of the modern world and need to be addressed with environmentally benign approaches. Green and sustainable synthesis of polymyrcene from β-myrcene via emulsion polymerization and its applicability as an oxygen scavenging material have been studied. The synthesized polymer was activated by using ultraviolet (UV) light in order to trigger the oxygen scavenging mechanism. The synthesized polymer was characterized for its molecular weight by chromatography, thermal study, and structural changes by infrared spectroscopy. The z-average diameter of polymer particles is distributed in the range of 77.9–105.5 nm, which gives a better surface area for scavenging. The developed polymyrcene–photocatalytic system has exhibited an oxygen scavenging capacity of 1077 mL O2/g in 20 days at 25 °C. Similar values were obtained within 4 days when exposed to 45 °C. The reaction rate kinetics were analyzed by using collision theory, and the activation energy involved was estimated. The results proved that polymyrcene could be efficiently utilized as an oxygen absorber in active food packaging.

“…As we all know, poly (L-lactic acid) (PLLA) is a linear aliphatic polyester with excellent biodegradability [ 1 ], solvent resistance [ 2 ], and biocompatibility [ 3 ], and good mechanical properties [ 4 ], abundant resource [ 5 ], and wide application. Thereby, PLLA can be used as a potential biomass matrix material for anti-icing [ 6 , 7 ], tissue repair [ 8 ], organ replacement [ 9 ], oil-water separation [ 10 ], and so on. There are various methods for preparing hydrophobic PLLA materials, including the template method [ 11 ], electroplating method [ 12 ], electrospinning method [ 13 ], phase separation method [ 14 ], sol-gel method [ 15 ], chemical grafting method [ 16 ], etc.…”

Integrating Fly Ash-Controlled Surface Morphology and Candle Grease Coating: Access to Highly Hydrophobic Poly (L-lactic Acid) Composite for Anti-Icing Application

New ways of recycling fly ash are of great significance for reducing the environmental pollution. In this work, biodegradable hydrophobic poly (L-lactic acid)/fly ash composites for anti-icing application were successfully fabricated via a facile solvent-volatilization-induced phase separation approach. A silane coupling agent of 3-(Trimethoxysilyl) propyl methacrylate was used to decorate a fly ash surface (FA@KH570) for strengthening the interface bonding between fly ash and poly (L-lactic acid). Moreover, FA@KH570 could obviously enhance the crystallinity of poly (L-lactic acid) (PLLA)/FA@KH570 composites, which accelerated the conversion from the liquid-liquid to the liquid-solid phase separation principle. Correspondingly, the controllable surface morphology from smooth to petal-like microspheres was attained simply by adjusting the FA@KH570 content. After coating nontoxic candle grease, the apparent contact angle of 5 wt% PLLA/FA@KH570 composite was significantly increased to an astonishing 151.2°, which endowed the composite with excellent anti-icing property. This strategy paves the way for recycling waste fly ash and manufacturing hydrophobic poly (L-lactic acid) composite for potential application as an anti-icing material for refrigerator interior walls.
