Abstract:
Highly porous, lightweight aerogels were developed based on cellulose extracted via industrial Kraft treatments from vine shoot (S) with the aim of valorising a currently generated waste and eucalyptus (EU) to reduce seasonality. In order to enhance their hydrophobicity and mechanical resistance, a poly-lactic acid (PLA) coating was applied through two different methodologies: spray- and pipette-coating. The resulting materials presented low densities (23-80 kg/m3) with improved mechanical performance, revealing a notable augment in compressive strength after PLA coating (up to 20-fold increase, reaching 7.04 N/cm2), while maintaining low thermal conductivity values around 0.0305 W/mK. These results highlight the potential of the developed aerogels as sustainable and biodegradable protective packaging for wine bottles, offering a balance between thermal insulation, mechanical performance, and circular economy benefits.
