Biopolymer blended films of poly(butylene succinate)/cyclic olefin copolymer with enhanced mechanical strength for packaging applications

Abstract

The demand for biodegradable materials is on the rise because humanity is now more concerned about a sustainable lifestyle than ever before. In this regard, we present solution casting synthesized novel biopolymer blended films of poly(butylene succinate)/cyclic olefin copolymer (PBS/COC) for packaging applications. These films were characterized by X‐ray diffraction (XRD), Fourier transform infrared microscopy (FTIR), scanning electron microscopy (SEM), universal tensile testing (ASTM D882 standard), and antibacterial Disc diffusion tests using gram‐negative Escherichia coli (E.coli) and gram‐positive Staphylococcus aureus (S.aureus) bacteria. The XRD and FTIR revealed the type of bonding to be physical in‐between the constituent polymers; ensuring the biodegradable nature of their blends, while the thickness of films was found to be <100 μm. The SEM, tensile, and antibacterial testing concluded that 30%PBS with 70%COC by weight blending is the best composition; showing a compact/pin‐holes free morphology, the highest strength of 91 MPa, and contact inhibition with E.coli and S.aureus bacteria.

Development of biopolymer composite films based on chicory extract reinforced polyvinyl alcohol/chitosan blend via green approach for flexible optoelectrical devices

“…1 The development of ecologically and bio-friendly functional materials that are exact alternatives to nonbiodegradable petrochemical polymers has been a hot topic for research. [2][3][4] Interdisciplinary materials are under research for the fabrication of novel materials with extra performances. Polyvinyl alcohol (PVA) is a semicrystalline, nontoxic, biodegradable, thermostable, and biocompatible linear synthetic polymer.…”

“…Since the world is now focusing on sustainable development and building a green world, protecting our ecosystem from all sorts of pollution and converting waste materials into useful ones must be the major targets 1 . The development of ecologically and bio‐friendly functional materials that are exact alternatives to nonbiodegradable petrochemical polymers has been a hot topic for research 2–4 .

High performance biopolymer blend nanocomposites derived from cashew gum/polyvinyl alcohol/boehmite for flexible electronic devices

“…Thus, the usage of bio‐friendly polymers rather than petroleum‐derived polymers will be a viable option for waste disposal and reducing hazards to the environment. Biodegradable polymers have recently received a lot of attention for their superior processability, mechanical strength, flexibility, nontoxicity, renewability, biodegradability, ease of availability, and affordability in different electronic and electrochemical applications 1–3 …”

“…Biodegradable polymers have recently received a lot of attention for their superior processability, mechanical strength, flexibility, nontoxicity, renewability, biodegradability, ease of availability, and affordability in different electronic and electrochemical applications. [1][2][3] Among the vast varieties of biopolymers, exudate gums have piqued the interest of academics in recent years due to their diverse applications, primarily in the food sector as emulsifiers, stabilizers, and thickening agents. 4,5 Cashew trees (Anacardium occidentale) are aboriginal of Brazil, but they are now widely planted in India.…”

Preparation the composite with high toughness and strength by recycled cyclic olefin copolymer

“…[1][2][3][4][5] Compared with traditional transparency plastics such as polycarbonate (PC) and polymethyl methacrylate (PMMA), COC resin has been widely used in high-end lenses, medical equipment, [6] and pharmaceutical packaging [7] due to its high water vapor barrier rate, [8,9] good chemical resistance, [10] and high biocompatibility. [11] But, due to the high requirements for materials in the optical field and pharmaceutical field, recycled COC resin is not permitted to employ again. Thus, the recycling of this stable COC resin becomes more and more urgent.…”
