Additive manufacturing of smart polymeric composites: Literature review and future perspectives

Abstract

The latest developments in smart systems for improved human lives with advanced biomedical devices have evolved out of multi‐disciplinary scientific studies, including medicine, biology, material sciences, design, manufacturing, artificial intelligence, microelectronics, and so forth. The growth of such intelligent systems is primarily possible with innovative materials, which demonstrate the response to various external stimuli like temperature, heat, moisture, light, electromagnetic field, and chemical alteration. Such materials have been recently fabricated using different additive manufacturing techniques to devise personalized unique, complex, and novel structures that can adjust to external conditions over time and are specifically attributed to 4D printing. Novel materials that can further improve such systems continued to be explored and employed. This review paper investigates the additive manufacturing of functional polymer nanocomposites, which offer compliant structures with flexible manufacturing processes with high strength, low cost, and long‐term stability. This study aims to deliver a comprehensive and deep understanding of the latest developments in materials, design, manufacturing, fundamental mechanisms involved, and future possibilities in this area of research.

Enhancing the tensile properties of PA6/CNT nanocomposite in selective laser sintering process

“…Selective laser sintering (SLS) is a significant branch of 3D printing that enables the manufacturing of complex parts by using a CO 2 laser beam to selectively sinter the powder materials based on three-dimensional CAD model. [1][2][3] The powder materials are solidified layer by layer successively using a focused laser radiation system. The new layer of powders is then deposited on upper surface of the prior layer and the laser beam irradiates on new layers to produce multiple layers.…”

Perspectives on development of biomedical polymer materials in artificial intelligence age

“…Cytotoxicity for non-target cells is a major problem in polymeric materials, the use of polymeric materials in human treatment depends on the low cytotoxicity of the carrier at the required therapeutic dose. 134 Due to its potential environmental impacts, toxicity is also a serious problem for polymeric materials used in consumer goods. Since the design of polymeric materials and the development of toxic filter presses have potentially high advantages, the ability of the silicon method to predict cytotoxicity is very desirable.…”

Membrane Surface Modification via In Situ Grafting of GO/Pt Nanoparticles for Nitrate Removal with Anti-Biofouling Properties

“…Meanwhile, polysulfone (PSF) is a commercially available polymeric material used in NF membranes [ 10 ]. Although PSF polymer offers convenient features like significant thermal, mechanical, and chemical stabilities along with an affordable price, it is susceptible to biofouling owing to its hydrophobic nature [ 11 ]. Hydrophobic surfaces of PSF membranes interact with proteins and other foulants [ 12 ], whereby a bacterial film forms on the membrane surfaces.…”
