“…While a majority of the transverse ZA work has focused on extreme thermal gradients generated by nanoscale gaps, Kumacheva and coworkers, in two early reports roughly coinciding with the previously discussed transverse ZA studies, demonstrated MB convection of polymer resins was driven by an imposed thermal gradient of only 10 4 -10 6 K=m. 58,59 The morphologies observed in these studies were completely attributed to the thermocapillary mechanism with extremely low aspect ratios (10 22 -10 23 ). Consistent with eq 6 at the low gradient limit, the period of the hexagonal structures that emerged decreased linearly with increasing temperatures.…”

The phenomenon of thermocapillarity, the response of fluids to thermal gradients due to thermal alteration of their surface tension, was first reported over a century ago. Since then, research has focused generally on either the fundamentals or mitigation of this effect during the processing of materials. Only in the past two decades has the deliberate use of thermocapillary forces for the patterning of polymers been actively pursued, either for the ordering of internal structure or the introduction of topographic features. This review seeks to highlight this work and to identify directions for further investigation. In particular, while thermocapillary forces are often inextricably bound to other mechanisms, there are emerging directions in the deliberate coupling of forces to improve the capabilities of each mechanism. Further, the applications of thermocapillary patterning to polymer-nanoparticle composites has recently provided another promising route to active architectures.

“…1 Alkoxysilanes are the most widely used protective materials for the conservation of such historic houses during the past decades. [2][3][4][5] However, tendency to crack during shrinkage and drying due to their brittleness, 6 long curing time 7 and slight colour alteration are oen observed when alkoxysilanes are used. By contrast, the reported uorosilicone polymers 8,9 have some advantages in terms of better mechanical strength, weather resistance, and shorter curing time, but their hydrophobicity is poor, which limit their application in the conservation of masonry.…”

“…In the fabrication of polymer coating, one of the strategies is to allow isocyanates to react with hydroxyl compounds to get radiation curable coating slurries. [20][21][22][23] The polyurethane resin, made of, e.g., IPDI, has excellent higher surface energy, photo-stability and chemical resistance and it is commonly used in paints, coatings, printing stamps and adhesion agents. 22,24,25 HEMA is one of poly-acrylate derivates among acrylate-based resin, and acrylate-based monomers are used widely because of their low cytotoxicity and high heat resistance, while acrylate-based resin is prone to have a slower curing rate.…”

Compared with parts fabricated via traditional methods, such as injection or compression molding, polymeric parts produced by 3D stereolithography (SLA) have poorer mechanical properties. Here, we demonstrate a cross-linking strategy used in the coating field to attain long chains for resin prepolymerization to obtain final resin parts which can expand the application of SLA. Isophorone diisocyanate (IPDI), 2-hydroxyethyl methacrylate (HEMA) and polyethylene glycol (PEG)-based prepolymer have long chains, making it easier for them to form dense structures. However, the prepolymer has high viscosity and can solidify in the absence of a laser. Thus, three kinds of adjuvants were added to dilute the prepolymer to make the slurry suitable for 3D-printing. Slurries were cured with different laser powers and scanning speeds. Diluents are found to affect the curing properties differently. With the diluent 2-hydroxyethyl acrylate added into the prepolymer, shrinkage of printed parts is lower than 1.3%. With the diluent ethylene glycol monophenyl ether, the density range of printed parts is between 1.187 g cm À3 and 1.195 g cm À3 , which is higher than that of commercial PVC and PET. The three resins vary in density and hardness within a small range when the scanning speeds change. A relatively flat surface, high density and hardness can be obtained when the laser power is at 195.5-350 mW. Resin with this cross-linking strategy can expand the underutilized stereolithography's application from prototyping to actual parts by producing more functional components with excellent performance.
