Academic translational research efforts to industry are often an underlying sought-after goal among the researchers. Through the interchanges of research endeavors between academia-industry, great innovations can/has been achieved that cater to the real-world application by bridging “industrially relevant” problem solving with pursuing fundamental concepts. It is pertinent that most of the studies from university level research works may not translate into demonstrable products in the market as many factors are at play here which are beyond the scope or reach of academic researchers. Funding support, individual goals of researchers, socio-economic factors and most importantly the technical know-how of generating revenue strategies to make it a profitable startup are few of the factors that have slowed the pace of collaborative efforts. However, we believe that the most critical factor is identification of the critical parameters that solves long standing problems that hinder the scale-up of the lab scale research into marketable products. To illustrate this, we take three most relevant examples, devices for fuel generation, devices to utilize solar radiation and devices for sensing and other related applications. In this perspective article, we provide an in-depth case study of each of these critical parameters to comment on the direction of research avenues that can serve as step-stones for the commercialization of university-level lab research studies.

“…Likewise, due to their excellent strength and EMI shielding capabilities, CNT/SiC composites satisfy the requirements of sophisticated structural vehicles such as spacecraft [138 ]. A intriguing composite prospect is ink that can be 3D printed with improved mechanical and electrical properties by combining various concentrations of CNTs with nanoclay [54]. Due to their dielectric and water-absorbing qualities, fly ash polymer nanocomposites are also frequently employed in automotive body parts [114 ].…”

Due to their superior mechanical, thermal, electrical, and tri-biological characteristics, carbon nanotubes (CNTs) have been widely used in a variety of industries, from aerospace to energy, since their discovery in 1991. Their compact size, amazing tensile strength, and light weight They are often used as reinforcements in metals, plastics, and even additive manufacturing due to their popularity and conductivity. In this analysis, we present a list of these structures and an in-depth discussion of the CNT-reinforced materials can be processed using a variety of techniques, including chemical vapor deposition (CVD), ball milling, both laser melting and hot pressing. The restrictions in the production and processing of these composites additionally discussed, strengthened by many authored works. To comprehend how these composites' properties change in relation to other parameters, such as a wide range of variables, such as temperature, CNT length, diameter, etc. A summary is given, explaining various methods for performing experimental analysis and providing convincing arguments for putting the changes' causes in. Therefore, we investigate the specialized uses of these CNT-reinforced composites in industries like aerospace, energy, biomedicine, and auto, and how they can be handled further, altered to make room for less expensive and more effective fixes going forward.

“…The main reason for this is that photopolymerization is a sequential process which starts from the surface, and therefore any filler embedded in a photopolymer tends to degrade the material, impeding double C=C bonds to be converted [ 11 , 12 ]. The addition of nanoparticles, including carbon-based nanofillers, such as carbon black, graphene nanosheets, or carbon nanotubes in a resin, can significantly improve the electrical, thermal, or mechanical properties of the resultant polymeric nanocomposites, providing great potential for 3D-printed nanocomposites for application in electromagnetic shielding, stretchable sensors, biosensors, and energy storage devices [ 13 , 14 , 15 , 16 , 17 , 18 ].…”

Thermomechanical Properties of Carbon Nanocomposites PEGDA Photopolymers

In this work, UV-curable resin poly (ethylene glycol) diacrylate (PEGDA) was reinforced with three different types of nanofillers: pristine graphene (G), multiwalled carbon nanotubes (MWNTs), and a hybrid of MWNTs and graphene 70/30 in mass ratio (Hyb). PEGDA was mixed homogenously with the nanofiller oligomer by shear mixing and then photopolymerized, affording thin, stable films. The thermomechanical properties of the afforded nanocomposites indicated the superior reinforcing ability of pristine graphene compared with MWNTs and an intermediate behavior of the hybrid.
