3D/4D Printing of Polyurethanes by Vat Photopolymerization
نویسندگان
چکیده
Vat photopolymerization relies on the light-induced polymerization of liquid photopolymer to produce targeted structure. Among all polymers prepared by vat photopolymerization, due their numerous properties polyurethanes have recently gained great attention in industrial and academic fields. In this review article, recent progress printing techniques, resin compositions, applications related 3D/4D are highlighted.

Origami by frontal photopolymerization
Origami structures are of great interest in microelectronics, soft actuators, mechanical metamaterials, and biomedical devices. Current methods of fabricating origami structures still have several limitations, such as complex material systems or tedious processing steps. We present a simple approach for creating three-dimensional (3D) origami structures by the frontal photopolymerization method...
متن کاملPixellated Photonic Crystal Films by Selective Photopolymerization
Hierarchical microstructures of colloidal crystals have attracted enormous research efforts due to their potential uses in display devices, optical communications, catalytic supports, biosensors, and acoustic materials. Recent progress in selfassembly approaches for such microstructures has shown that regular arrays of microspheres can be easily grown by several clever ways based on well-establ...
متن کاملCoagulation of Polyurethanes
The polymer most often used for the coagulation process is polyurethane. Nearly all leather substitutes sold in the world consist partially or totally of polyurethanes. Therefore a whole chapter is dedicated to the coagulation of polyurethanes. In 1951 a coagulation process for a polyurethane was published for the first time [1]. Since 1954 [36] additional process steps have been developed to p...

15 صفحه اولCache-Oblivious VAT-Algorithms
The VAT-model (virtual address translation model) extends the EM-model (external memory model) and takes the cost of address translation in virtual memories into account. In this model, the cost of a single memory access may be logarithmic in the largest address used. We show that the VAT-cost of cache-oblivious algorithms is only a constant factor larger than their EM-cost; this requires a som...
