A Brief Evaluation of Antioxidants, Antistatics, and Plasticizers Additives from Natural Sources for Polymers Formulation

Abstract

The circular economy plays an important role in the preparation and recycling of polymers. Research groups in different fields, such as materials science, pharmaceutical and engineering, have focused on building sustainable polymers to minimize the release of toxic products. Recent studies focused on the circular economy have suggested developing new polymeric materials based on renewable and sustainable sources, such as using biomass waste to obtain raw materials to prepare new functional bio-additives. This review presents some of the main characteristics of common polymer additives, such as antioxidants, antistatic agents and plasticizers, and recent research in developing bio-alternatives. Examples of these alternatives include the use of polysaccharides from agro-industrial waste streams that can be used as antioxidants, and chitosan which can be used as an antistatic agent.

Chlorine Speciation by GC-XSD for the Characterization of Plastic Pyrolysis Oil as a Cracker Feedstock

“…This HOCl further reacts with ethylene to form 2-chloroethanol. Several other additives or processing aids like Cl-biocides, Cl-antistatic agents, Cl-catalysts, cross-linking agents, Cl-colorants and solvents are reported to contribute to numerous Cl-species. ,− …”

Antioxidant Metabolism Pathways in Vitamins, Polyphenols, and Selenium: Parallels and Divergences

“…Some studies suggest that their benefits and large-scale clinical trials have not consistently found positive effects, and excessive intake may even be harmful. Antioxidants are not only used in medicine, but also in various industries as preservatives in food and cosmetics, preventing the degradation of rubber, polymers, and gasoline [ 10 ].…”

Evaluation of Starch–Garlic Husk Polymeric Composites through Mechanical, Thermal, and Thermo-Mechanical Tests

“…The planet increasingly faces environmental problems due to the indiscriminate use of plastics and raw materials derived from petrochemical sources, and these materials are being used in many sectors of the world economy [ 1 ]. The demand and exploitation of polymers are due to their low production cost, lightness, versatility, and durability (some of which remain in the environment for hundreds of years) [ 2 ]. However, with short periods of use, they quickly become waste.…”

“…However, with short periods of use, they quickly become waste. The accumulation of waste and its disposal produce a greater ecological footprint and a severe environmental problem with accumulation in landfills [ 2 ]. Additionally, plastic waste represents a threat to marine life and other wildlife, public health, and the economic, social, and environmental sectors that directly depend on the health of marine life [ 3 , 4 ].…”

“…Unfortunately, the current transition rate from petrochemical polymers to biodegradable polymers is low and inconsistent. For this reason, the socioeconomic system must be based on a circular economy and the use of biodegradable materials to mitigate environmental pollution derived from plastics [ 2 ]. On the other hand, waste recycling is considered one of the main processes to significantly minimize the consumption of virgin materials and increase the amount of recycled waste [ 6 ].…”
