One of the systems that will be pre-requisitely required is the sealing of biopolymer. Conventional sealing techniques, viz. heat sealing and chemical adhesive, are not suitable for sealing biopolymers. In this work, we have demonstrated the formulation of biopolymer-based glue, which is effective in sealing biopolymers. The formulation includes a rice biopolymer-based composite material with chitosan and sodium alginate and, followed by cross-linking with a natural base (pH∼ 12). The developed glue formulation is effective in joining the litho paper, cotton, and guar gum-chitosan cross-linked biopolymer film (GG-CH-C). The lap shear strength of the prepared glue formulation is maximum for the substrate sodium alginate-chitosan cross-linked biopolymer film. In the presence of high humidity (100 % RH), the lap shear strength of the prepared glue formulation decreases; however, it was still measurable and found to be (2.99 ± 0.34) MPa. A plausible mechanism is discussed to explain the chemical interactions between the prepared glue formulation and the biopolymer film substrates. The cytotoxicity of the prepared glue is tested against CC1 hepatocytes. Hence, rice-biopolymer-based composite is an excellent glue material that is found to be effective in joining two biopolymeric surfaces.</div></div>","PeriodicalId":100958,"journal":{"name":"Next Materials","volume":"7 ","pages":"Article 100507"},"PeriodicalIF":0.0,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143159992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hybrid nano-composites exhibited great potential when conducting polymers were combined with either transition metals, their oxides, metal chalcogenides and/or chalcogens. Consequently, amongst the conducting polymers, polypyrrole (PPy) has gained high popularity in regards to its attributes. Researchers have developed number of methods for synthesizing PPy and their nano-composites with chalcogens/chalcogenides over the past two decades for different fields of application.

At the core of such an energy source is the proton exchange membrane, which is made to be a good conductor for protons while isolating electrons to flow from the anode to the cathode, imprinting them with an external circuit and generating electricity in the process. Today, the most advanced fuel cell proton exchange membranes are perfluoro sulfonic acid-based (Nafion) membranes, which were initially developed more than 50 years ago.

However, their low power conversion efficiency (∼15.2%) hinders practical applications. This is primarily owing to ineffective dyes, significant recombination at solid/liquid interfaces, and limitations of TiO₂, the conventional photoanode material, especially poor light harvesting and electron transport. Moreover, Pt, the traditional counter electrode material, is costly and unstable due to its scarcity and low corrosion resistance to I₃ˉ, respectively. This increases the device cost and shortens its lifespan. Inspired by this, current research interests have shifted their focus from traditional materials to low-cost alternatives, including metal oxides, metal chalcogenides and perovskites, which offer competitive photovoltaic performance. Nonetheless, these alternative materials exhibit relatively low electrical conductivity, which compromises device performance. Thus, to improve device efficiency and sustainability, these materials have recently been coupled with highly conductive and stable carbon nanomaterials, particularly graphene-based materials.
