“…The maximum breaking strength is 26.5 MPa, which is much higher than those reported in the literature (Tables S1). [9][10][11]16,28,31] The breaking strain is 3.6 times of that of the pristine SA film and is comparable to those of the modified sodium alginate film reported previously (Table S2). Moreover, the Young's modulus and the strength at break are 10 MPa and 26.5 MPa, respectively.…”

“…Because of the abundance in nature, easy availability and good degradability, [9][10][11][12][13] sodium alginate is considered as a promising candidate for bioplastic. [14][15][16][17][18][19] In recent years, researches on sodium alginate-based bioplastics have been focused on the addition of various additives (such as cellulose, [20] multi-walled carbon nanotubes [21] ) which may help to improve their mechanical properties or the surface modification (using hydrophobic dodecyltrimethoxysilane, [22] dodecyl glycidyl ether, [23] silica nanoparticles [24] or methyl trimethoxysilane [25] ) which aims to increase its hydrophobicity. In addition, specific molecules have been grafted onto the sodium alginate molecular chain, such as β-carboxyethyl acrylate, acrylamide and ɛ-polylysine, ultimately conferring the sodium alginate with antimicrobial properties.…”

Plastic products are widely used in daily life. However, due to the non‐degradability, these plastics pose a great threat to the ecological environment and may even endanger human's health or animal's life. In this paper, we report a degradable and reusable supramolecular plastic. This plastic consists of FeCl3 and polyethylene glycol (PEG) modified sodium alginate (SA). Notably, this plastic exhibits excellent mechanical properties, i. e. it can withstand a load as heavy as 15 kg. This superior mechanical property originates from the double crosslinked network formed based on coordination interaction between Fe3+ and −COOH and hydrogen bonding among −OH, −COOH and oxygen atom from PEG. In addition, this plastic can be reused for multiple times with negligible change in the mechanical strength and is fully degradable. We thus believe the supramolecular plastic reported in the current study may show great promises in the practical fields.

“…The optimized alginate films showed a TS of 33.90 MPa, EAB of 3.58%, water vapor permeability of 2.63 × 10 −10 g Pa −1 s −1 m −1 , and water solubility of 33.73%. Manufactured bioplastic films with thicknesses ranging from 0.050 to 0.054 mm were suitable for commercial food packaging [162]. The TS property of bioplastic also changes after plasticizer addition.…”

“…The addition of commercial alginate disrupted the homogeneity of the Kappaphycus sp. blends resulting in a drop in TS and hydrophobicity of the biofilms [162]. The physicochemical properties of κ-carrageenan films extracted from Eucheuma cottonii seaweed were studied by Balqis et al [160].…”

The surge in global utilization of petroleum-based plastics, which notably heightened during the COVID-19 pandemic, has substantially increased its harm to ecosystems. Considering the escalating environmental impact, a pivotal shift towards bioplastics usage is imperative. Exploring and implementing bioplastics as a viable alternative could mitigate the ecological burden posed by traditional plastics. Macroalgae is a potential feedstock for the production of bioplastics due to its abundance, fast growth, and high cellulose and sugar content. Researchers have recently explored various methods for extracting and converting macroalgae into bioplastic. Some of the key challenges in the production of macroalgae bioplastics are the high costs of large-scale production and the need to optimize the extraction and conversion processes to obtain high-quality bioplastics. However, the potential benefits of using macroalgae for bioplastic production include reducing plastic waste and greenhouse gas emissions, using healthier materials in various life practices, and developing a promising area for future research and development. Also, bioplastic provides job opportunities in free enterprise and contributes to various applications such as packaging, medical devices, electronics, textiles, and cosmetics. The presented review aims to discuss the problem of petroleum-based plastic, bioplastic extraction from macroalgae, bioplastic properties, biodegradability, its various applications, and its production challenges.
