Special Issue Information

Dear Colleagues,

Polymer composites reinforced with fibers are a promising alternative to metal parts and the solution for light construction materials. Due to their exceptional properties (flexibility, functionality and formability in complicated design parts), fiber-reinforced polymer composites have found applications in many industrial fields (construction, automobile, aerospace), biomedicine, marine and others. The performance of the polymeric composite material mainly depends on the nature of the components, the degree of interaction between the components and the processing technology.

The purpose of this Special Issue is to highlight the latest original results in the development of composite materials based on synthetic and/or natural polymers and synthetic and/or natural fibers, with improved properties imposed by various applications.

The current study deals with an examination of strategies for the sequential treatment of corn stalks (CSs) in an integrated manner aiming to obtain papermaking fibers and to recover both lignin and hemicelluloses (HCs). Several pathways of valorization were experimentally trialed, focusing on getting information from mass balance analysis in an attempt to reveal the potential outcomes in terms of pulp yield, chemical composition, and papermaking properties such as tensile and burst strength. The raw lignin amounts and purity as well as separated hemicelluloses were also characterized. In this work, pulp yields in the range of 44–50% were obtained from CSs, while lignin and hemicelluloses yielded maximum values of 10 g/100 g of CS and 6.2 g/100 g of CS, respectively. Other findings of mass balance analysis evidenced that besides the papermaking pulp, the lignin and HCs also have interesting output values. The recovered lignin yield values were shown to be less than 50% in general, meaning that even if 67 to 90% of it is removed from CSs, only about half is recovered. The removal rates of hemicelluloses were found to be in the range of approx. 30 to 60%. About 15 to 25% of the original HCs could be recovered, and polysaccharides-based products with 67 to 75% xylan content could be obtained. Some key opinions were developed regarding how the mass balance could turn as a result of the chosen CS valorization set-up. The determined antioxidant activity showed that both lignin and hemicelluloses had interesting values for IC50. Full article
