Fossil-fuel-based plastics have many enticing properties, but their production has resulted in significant environmental issues that require immediate attention. Despite the fact that these polymers are manmade, some bacteria can degrade and metabolise them, suggesting that biotechnologies based on the principle of plastic biodegradation could be beneficial. Among different types of plastics, polypropylene (PP), either having low or high density, is one of the most consumed plastics (18.85%). Their debasement under natural conditions is somewhat tricky. Still, their debasement under natural conditions is rather difficult slightly. However, different scientists have still made efforts by employing other microbes such as bacteria, fungi, and guts bacteria of larvae of insects to bio-deteriorate the PP plastic. Pre-irradiation techniques (ultraviolet and gamma irradiations), compatibilizers, and bio-additives (natural fibers, starch, and polylactic acid) have been found to impact percent bio-deterioration of different PP derivatives stronglythe various. The fungal and bacterial study showed that PP macro/microplastic might serve as an energy source and sole carbon during bio-degradation. Generally, gravimetric method or physical characterization techniques such as FTIR, XRD, SEM, etc., are utilized to affirm the bio-degradation of PP plastics-based materials. However, these techniques are not enough to warrant the bio-deterioration of PP. In this regard, a new technique approach that measures the amount of carbon dioxide emitted during bacterial or fungus degradation has also been discussed. In addition, further exploration is needed on novel isolates from plastisphere environments, sub-atomic strategies to describe plastic-debasing microorganisms and improve enzymatic action strategies, and omics-based innovations to speed up plastic waste bio-deterioration.

Different kinds of biorenewable materials are rapidly emerging as potential alternatives to conventional petroleum-based synthetic materials. Among these materials, soy protein and its derivatives are of utmost interest and importance due to their advantages such as low cost, biodegradability, environmental friendliness, biocompatibility, renewability, and wide availability to name few. However, the poor physicochemical/mechanical properties as well as high moisture sensitivity of different soy based materials limit their successful applications in many fields. Different methodologies to produce new soy based materials with suitable functional groups are highly desired to increase their range of applications. So, in this Review, we have focused on the recent advances in the various graft copolymerization strategies involving soy and its applications. The synthesis, characterization, and methodology of graft-copolymer processing and resulting properties of the copolymers are fully covered. In this Review, ...

Chitosan is among one of the most important and most studied natural polymers. The cationic nature of chitosan makes it a polymer of high importance from environmental and biomedical point of views among the other natural polysaccharides. However, it also suffers from a few disadvantages and requires further development to achieve the targeted results and desired range of efficiency. To overcome some of the disadvantages of the pristine chitosan, it is most imperative to functionalize it with suitable functional groups. Therefore, it is highly desired to understand the chemistry of the reactions used to alter the surface characteristics of chitosan. Among various techniques presently being used to tailor the surface characteristics of chitosan, graft copolymerization is of the utmost importance. The aim of the present perspective is to describe the recent advances in the graft copolymerization of chitosan with particular emphasis on atom transfer radical polymerization (ATRP). This perspective describes t...

Recently there has been a growing interest in substituting traditional synthetic polymers with natural polymers for different applications. However, natural polymers such as cellulose suffer from few drawbacks. To become viable potential alternatives of synthetic polymers, cellulosic polymers must have comparable physico-chemical properties to that of synthetic polymers. So in the present work, cellulose polymer has been modified by a series of mercerization and silane functionalization to optimize the reaction conditions. Structural, thermal and morphological characterization of the cellulose has been done using FTIR, TGA and SEM, techniques. Surface modified cellulose polymers were further subjected to evaluation of their properties like swelling and chemical resistance behavior.

Natural biomasses such as natural fibers have been traditionally used as reinforcement in polymer biocomposites for structural applications. However, the resulting biocomposites are sensitive to harsh environmental conditions, which results in poorer properties in the biocomposites. Therefore, in the present study an attempt has been made to modify the surface properties of natural cellulosic biomass by the graft copolymerization technique. This article discusses the synthesis, characterization, and physicochemical properties of the raw and graft copolymerized natural cellulosic biomass. Cellulosic biomass–based grafted copolymers were characterized with scanning electron microscopy (SEM), FT-IR spectrophotometry, and thermal analysis (TGA) techniques.

Renewable cellulosic biofibers appear to be a promising substitute to synthetic fibers as reinforcement in different kinds of polymers. The prime objective of this work was to determine water absorption, chemical resistance, and mechanical properties of the green composites reinforced with ecofriendly natural cellulosic Saccharum cilliare fibers. The mechanical and physicochemical properties of the green composites have been investigated as a function of fiber loading for assessing their applicability in different potential applications in everyday life. The green composites thus prepared have been found to show a universal trend of an increase in properties with fiber loading up to 30%, and beyond this the properties decrease. A fiber/matrix interaction between the polymer and reinforcement has been analyzed based on the mechanical and morphological studies. Overall results suggest that the natural cellulosic S. cilliare fibers were capable of serving as a feasible reinforcement for green polymer composites. © 2012 Wiley Periodicals, Inc.
