In this article, gum copal-collagen hybrid based interpenetrating polymeric network (IPN) [(GcA-coll)-cl-poly(AAm-ip-AA)] has been used as a green adsorbent for the removal of Pb(II) and Cd(II) from waste water. Adsorption equilibrium was achieved in 9 h and pseudo-second-order model was found to be the closest fit to the kinetic adsorption data. Freundlich adsorption isotherm model was found to closely match with the sorption behavior of Pb(II) and Cd(II). The reaction parameters like initial metal ion concentration, adsorbent dose, pH, and the reaction time were optimized to get the hydrogel with maximum metal ion removal capacity (91.65% for Pb(II) and 95% for Cd(II)). The maximum percentage biodegradation of IPN was 80.25% by the compositing method. This IPN is an efficient, low cost potential adsorbent with excellent biodegradation and can act as an environment-friendly agent for removing heavy metals from water.

In quest of developing alternative technological solutions to increase agricultural production for feeding the growing population, extensive research is being performed in the agriculture area. In this regard, massive attention is being paid to develop polymer based engineered materials with a multitude of unique physicochemical properties using the concepts of modern polymer chemistry, materials technology, and nanotechnology. In this review, we provide an overview of recent advancements in polymer based engineered materials for striving toward sustainable agricultural practices. Herein, we discuss both natural and synthetic polymer based materials such as nanocarriers, electrospun fibers, hydrogels, and sensors for controlled agrochemical release, promoting growth, soil conditioning, sensing of soil condition, and other combined multiple actions in agriculture. Polymeric nanocomposites have promoted the growth of plants via an increase in the release rate of loaded agrochemicals. Polymer based nanofibers with a fiber diameter of <0.5 μm have stimulated the germination and nutrient supply to the plant along with providing a better seed coverage. Hybrid hydrogels possess the characteristic features of both natural and synthetic polymers, thus providing a better solution for the sustained release of agrochemicals in an economical way. Although the polymer based engineered materials have provided a significant contribution toward sustainable agriculture, still challenges such as the overall cost of fabricated material and practical feasibility in the agriculture fields need to be addressed. The side effects of the degraded products on the environmentally friendly microorganisms and the contamination of our natural underground water resources are some of the research areas which need to be explored further in the future.

A novel nonreleasing antibacterial hydrogel dressing with good reusability was prepared by polyethylene glycol dimethacrylate, N,N-methylene-bis-acrylamide, methyl methacrylate, 1-vinyl-3-butylimidazolium, and acrylamide. The ionic liquid of 1-vinyl-3-butylimidazolium was polymerized in the hydrogel to endow the hydrogel dressing with an antibacterial property. The successful synthesis of the hydrogel dressing was proven by FT-IR spectroscopy and energy-dispersive spectrometry. The morphology of the hydrogel was confirmed to be a porous and interconnected network structure by scanning electron microscopy. The resultant hydrogel dressing showed many desirable features, such as a good protein adsorption property and repeatable adhesiveness as well as excellent mechanical properties. Remarkably, the hydrogel dressing displayed broad antibacterial activity against bacteria Staphylococcus aureus and Escherichia coli and fungal Candida albicans. In addition, the hydrogel dressing applied locally on wounded skin of rats could effectively avoid early infection and further accelerate wound healing. The results indicated that the nonreleasing antibacterial hydrogel had potential application in wound dressing.
