Structure–Property Relationships in Poly (N isopropylacrylamide) Hydrogels: Toward Thermoresponsive Polymer Composites

By Nadeem Hasan, Lalit Mohan Nainwal, Poonam Arora, Gopal Dilip Wagh, Mrinal Kanti Bhoumik, Anuja P. Bhosale, Rajeeva Bhaskar, Amit Kumar Singh, Manish R. Bhise

Abstract: Poly(N-isopropylacrylamide) (PNIPAAm) hydrogels can shift from solid to gel and back again at body temperature. Due to their lack structural integrity, thermal stability, and mechanical strength, they are difficult to use. This study mixed PNIPAAm with biocompatible fillers like chitosan and silicon nanoparticles to create hydrogels with superior structure-property correlations. Free radical polymerization with ammonium persulfate/TEMED initiator and N,N′-methylenebisacrylamide crosslinker produced the composites. Scanning electron microscopy showed a denser, interconnected …

Next-Generation Biodegradable Polymer Composites: Enhancing Mechanical and Thermal Performance through Green Reinforcements

By Anupama Mishra, Prem Shankar Gupta, Sindhusaranya Balraj, Surita Basu, S. Mohamed Rabeek, Deepak Kohli

Abstract: Next-generation biodegradable polymer composites, combining compostable matrices such as polylactic acid (PLA), polyhydroxyalkanoates (PHAs) and starch-based polymers with green reinforcements (e.g., nanocellulose, lignin, agricultural residues and other bio-fillers), offer a pragmatic route to reconcile high performance with end-of-life sustainability. This paper examines recent advances in the design, processing and interfacial engineering of such composites to enhance mechanical stiffness, strength, toughness and thermal stability while preserving—or intentionally controlling—biodegradation pathways. Emphasis is …

Effects of Sub-Zero Temperatures on the Viscoelastic Properties of Magnetorheological Elastomer

By Suziyani Zin, Nur Azmah Nordin, Saiful Amri Mazlan, Mohd Aidy Faizal Johari, Abdul Yasser Abd Fatah, Rehnupreya Hentry Viension, Nur Hairunnisa Kamarudin

Abstract: Magnetorheological elastomers (MREs) are smart materials capable of tuneable stiffness and damping under applied magnetic fields. This renders the material as a promising candidate for adaptive vibration control and semi-active engineering applications. While their behaviour at elevated temperatures has been widely explored, limited attention has been given to their performance under sub-zero conditions, which are critical for cold-environment applications. As this has become an important concern, the study investigates the …

Analysis of Ageing and Degradation Behavior of Polyamide-12 for Sustainable Additive Manufacturing

By G. Venkata Nagamani, Sri Harsha Arigela

Abstract: Additive Manufacturing (AM), particularly High-Speed Sintering (HSS), has emerged as a transformative technology capable of producing complex thermoplastic parts with high efficiency and minimal material waste. The HSS process involves selective deposition of radiation-absorbing ink followed by infrared heating to consolidate polymer powders-most commonly polyamide-12 (PA12). While PA12 is widely used due to its excellent thermal stability and mechanical properties, the sustainability of HSS strongly depends on the reuse of …
