“…Other possible functional modifications on CNTs and graphene oxide surfaces include grafting of alkyl chains [ 96 ], polystyrene sulfonate, aminostyrene [ 97 ], zinc oxide [ 98 , 99 ], thiols [ 21 , 30 ], and thiol-ended hyperbranched polymers [ 31 ]. Alternative chemical methods that involve the use of non-toxic solvents or a bio-approach have also been proposed [ 100 , 101 , 102 , 103 , 104 , 105 ]. The modification of the MXenes surface can be achieved by the creation of thermally stable oxygen functional groups, able to assure interfacial adhesion with the epoxy matrix [ 50 ].…”

“…The incorporation of nanoparticles in epoxy resins allows modification of many properties. In comparison to the neat polymer, enhanced mechanical properties [ 6 , 16 , 27 , 32 , 35 , 45 , 57 , 69 , 85 , 101 , 106 , 108 , 109 , 110 , 111 , 112 , 113 , 114 , 115 , 116 , 117 , 118 , 119 ], improved corrosion resistance [ 21 , 25 , 59 , 64 , 70 , 92 , 108 , 120 , 121 , 122 , 123 , 124 , 125 , 126 ], increased thermal and electrical conductivity [ 5 , 15 , 16 , 17 , 27 , 45 , 86 , 87 , 101 , 109 , 110 , 117 , 127 , 128 ], high dielectric permittivity and low dielectric loss [ 93 ...…”

“…A large amount of energy, therefore, is required to allow the crack to pass the uniformly dispersed nanofillers and to propagate until the fracture failure [ 45 , 101 , 113 ]. This mechanism leads to significant increases in the mechanical properties of the material.…”

“…Suitable dispersion of the nanofiller is a key factor to obtain nanocomposites with high mechanical properties [ 17 , 116 ]. In those regions where agglomeration of nanoparticles takes place, cracks finds weaker pathways, energetically favorable, and fractures more easily appear [ 101 ] ( Figure 8 ).…”

“…This effect positively affects the electrical properties since conduction takes place at lower loadings of nanofiller than those involving intimate contact between the nanoparticles [ 140 , 141 ], even if a suitable tunneling distance is necessary to provide conduction; for example, CNTs in polymer matrices have a maximum tunneling distance of 1.8 nm [ 142 ]. The presence of uniformly dispersed nanofillers is, once again, a basic requirement [ 101 ] and a critical loading, the so-called electrical percolation threshold ( Figure 10 ), is needed to obtain electrical conductivity [ 9 , 15 , 17 , 109 , 110 , 127 , 139 , 143 , 144 ]. The percolation threshold is usually achieved using 0.5–1 wt.% loads of nanofiller, but nanoparticles’ functionalization can further decrease the required loading content [ 100 , 102 ].…”

This paper aims at reviewing the works published in the last five years (2016–2020) on polymer nanocomposites based on epoxy resins. The different nanofillers successfully added to epoxies to enhance some of their characteristics, in relation to the nature and the feature of each nanofiller, are illustrated. The organic–inorganic hybrid nanostructured epoxies are also introduced and their strong potential in many applications has been highlighted. The different methods and routes employed for the production of nanofilled/nanostructured epoxies are described. A discussion of the main properties and final performance, which comprise durability, of epoxy nanocomposites, depending on chemical nature, shape, and size of nanoparticles and on their distribution, is presented. It is also shown why an efficient uniform dispersion of the nanofillers in the epoxy matrix, along with strong interfacial interactions with the polymeric network, will guarantee the success of the application for which the nanocomposite is proposed. The mechanisms yielding to the improved properties in comparison to the neat polymer are illustrated. The most important applications in which these new materials can better exploit their uniqueness are finally presented, also evidencing the aspects that limit a wider diffusion.

Structural and compositional diversities of proteins generate a number of functions for fabricating novel and advanced materials. Recent progress in protein engineering endows flexible approaches and new functionalities, which makes the fabricated materials potentially applicable in a broad spectrum of fields. Such engineering strategies by applying proteins alone or together with other molecules derive numerous functional materials such as patterned nanometal materials/nanometallic compounds, well‐designed nanocomposites, etc. Advantages in materials’ tunability, property improvement (e.g., electronic and mechanical properties, etc.), functionalities, and biocompatibility have been demonstrated, thus providing alternatives to existing materials via conventional methods. This review summarizes and discusses the strategies of fabricating functional materials using proteins as the critical contributors. Benefiting from their versatility, proteins find their roles in engineering functional materials via acting as structure‐control agents, reaction agents, and battery components, which are emphasized in this review. The strategies of each group of functions are specifically detailed. Properties of protein‐engineered functional materials and their potential applications in the fields of microelectronics, energy storage and conversion, sensor devices, etc. are also reviewed.

It is an urgent need that defect repair can develop from simple device fixation to living tissue reconstruction, from short life function replacement to permanent regeneration repair. At present, bone transplantation has become the second largest transplantation surgery after blood transfusion, and artificial bone transplantation generates great hope for the repair and treatment of bone defect. In order to repair bone defect, artificial bone must have good biological properties and sufficient mechanical properties, and it should also have the shape matching to bone defect site and the connected porous structure. For structures and properties requirements of artificial bone, in this review three major challenges faced by artificial bone transplantation are systemtically analyzed and current methods and strategies to address these issues are discussed: 1) the need for developing a type of bone scaffold material with both biological and mechanical properties, 2) the need for realizing the controllable fabrication of individual shape and multistage pore structure of bone scaffold, 3) the need for realizing the transformation from man‐made structure to biological structure. Besides, it summarizes the advantages and disadvantages of these methods and discusses the potential future directions of structural and functional adaptive artificial bone for bone defect regeneration.
