Special Issue Information

Aim and Scope: The importance of materials has been, is and will be very important for life. Recently, the technology of materials is being focused on polymers and composite materials, since with them it is possible to obtain a material with optimal properties for the required application. Specifically, the convergence of materials science with materials engineering leads to the combination of the production and characterization of materials for different specific applications. Nowadays, polymer-based materials have been proposed for different applications like foods (formation and stabilization of foods, supply dietary fibers or micro- and nanoencapsulation), packaging (structural and mechanical properties or edible films), cosmetic and pharmaceutical industry (low cost, sustainability and naturalness, even in regenerative medicine as biomaterials.

Abstract

Efforts to find new resources to replace the synthetic fibers such as glass and carbon fibers in the development of polymeric and cementiceous matrices based composites have been made to take care of growing environmental concerns. Bamboo is one such lignocellulosic material, which is abundantlygrown in most developing countries and is sustainable and strong. Of the various varieties of bamboo grown in Brazil, Taquara-lixa stands out due to its large availability and low cost besides its physical and mechanical characteristics. However, not many studies have been reported on its use in the development of composites probably due to very little reports on various properties of this fiber. Accordingly, this paper presents extraction of fibers from the stem of taquara-lixa bamboo, their characterization in respect of chemical composition, pH, crystallinity index and thermal stability. Further, effect of alkali treatment of fibers on the chemical composition, thermal stability and crystallinity index has also been presented. While the alkali treatment has reduced the moisture and lignin contents as well as solubility in cold and hot water, holocellulose content increased slightly. There was no change in the values pH, crystallinity index and thermal stability of the fibers with the alkali treatment.

Abstract

Continuing the studies on the Brazilian lignocellulosic fibers by the authors to increase their applications, this paper presents chemical and thermal properties of açai and curauá fibers, which are some of the unique fibers of the country. While there is very limited published report on the effect of chemical treatments of açaí fibers, no report is available of sodium borohydride (sodium tetrahydroborate) treatment of both these fibers. This paper presents effect of alkaline treatments with and without sodium borohydride on these two fibers for possible use in polymer based composites. Chemical composition studies of both the fibers revealed these chemical treatments increased cellulose and decreased hemicelluloses contents of both the fibers; while spectroscopic studies using Fourier transform infrared showed that wide hydroxyl bands are not affected by the chemical treatments, while other bands showed slight variations in their trough parts compared to those of fibers without any treatment. Both the fibers exhibited improved thermal stability after the alkaline treatment. These results clearly underlined that the chemical treatments were effective in for improvement of their thermal properties, while the effectiveness of these treatments on fibers surfaces can be seen when they are used in a polymer matrix and removal of components.

Abstract

Polyvinyl alcohol (PVA) is a biodegradable, biocompatible synthetic polymer that has demonstrated good performance in several areas of application as packing, agriculture but mainly in biomedicine field. The natural fibers, or lignocellulosic fibers, play an increasingly important role in polymer composites, since they are not only “biofriendly” polymers, easy to obtain and abundantly found in nature, but also add great improvement in the physical-chemical properties of synthetic polymers, at a relatively low cost. Such fibers are found in several types of plants and can be obtained by different methods (chemical, physical or biological), which can provide some different properties needed in each case of application. This article overviews the most recent advanced studies in the development of PVA composites reinforced with natural fibers, as well as the improve properties, processing methods, characterizations tests and the applications of these composites in the industry field.

Abstract

Nanocellulose is emerging as an advanced reinforcement material for composites with higher mechanical properties at lower fiber loading, retaining its transparent nature with better processability and ecofriendly characteristics compared to natural fiber based systems. Various cellulose resources including plant fibers such as sisal, banana, coir, jute, areca fibers, rice husk etc. and wood pulp have been used for the synthesis of nanocellulose by chemical as well as mechanical processing including steam explosion to make these nanofibers in bulk with cost effective processes. In-situ crosslinking strategies have been tried in composites with biopolymer matrices such as poly(lactic acid), poly(glycolic acid), poly(butylene succinate) etc. for forming interpenetrating network structures in nanocomposites for better properties. The possibility for functionalization and self-assembly in nanocellulose opened up a novel area of composites with self-aligned fiber incorporated composites showing applications in stimuli responsive materials and devices especially in biomedical applications having better biocompatibility. These composites with improved gas barrier properties and ecofriendly nature is the best bet for packaging and advanced material applications. This review paper covers all the above and presents some perspectives for the future.
