This work describes the fabrication of silver-patterned polymeric devices via light-based 3D printing methods from a tailored resin. An acrylate resin containing silver nitrate (AgNO3) as a silver precursor is employed to generate silver nanoparticles (AgNPs) through the in-situ reduction of the metallic salt. The silver-based resin is processed through a customized stereolithography SL-3D printing

Black phosphorus nanosheets (BPNS) cannot be directly applied in moist air due to their chemical instability from their thin layer structures adsorbed and transferred oxygen atoms easily. Here, a universal strategy for stabilizing BPNS was proposed by exfoliating black phosphorus with one-dimensional nanoparticles based on cellulose nanocrystals (CNCs). Thin layers of BPNS were obtained in water and

Four-dimensional (4D) printing of shape memory polymers enables the production of thermoresponsive objects. In this contribution, a facile printing strategy is followed for an in-house synthesized thermoplastic poly(ether urethane). Processing by means of fused filament fabrication (FFF), in which the difference between nozzle temperature and material-specific glass transition temperature of the polymer

Microfluidics have been used for several decades to conduct a wide range of research in chemistry and the life sciences. The reduced dimensions of these devices give them advantages over classical analysis techniques such as increased sensitivity, shorter analysis times, and lower reagent consumption. However, current manufacturing processes for microfluidic chips either limits them to materials with

Micro-distance sensor, which can accurately detect the micro-distance change, possesses significant applications in the cutting-edge technologies including biomedicine, energy storage and info-communications. However, the high cost, complicated operation and stringent testing requirements of the existing micro-distance sensors limit their widespread application in the frontier fields, especially for

Thermoplastic polyamide elastomers (TPAEs) have emerged as important thermoplastic elastomer materials with significant potentials owing to their excellent low-temperature flexibility, easy processability, lightweight, good thermal stability and mechanical properties, etc. Over the last few decades, TPAEs have rapidly developed into a large variety of kinds of TPAEs. Striking advancements have been

Magnetic actuators, which use magnetic effects for actuation, are very useful in many areas, such as electrical equipments, soft robots and medical instruments. However, they inevitably suffer damage during long-term use, leading to mechanical failure. Introduction of self-healing concept can solve this problem to a certain extent and extend their service life. Herein, a room-temperature self-healing

Flexible sensor technologies have gained extensive interest in recent years owing to the increasing demands of wearable electronics. Here, we propose a flexible strain sensor with enhanced sensitivity by designing an entirely new sensing approach for strain detection. The sensing approach uses an over-balanced planar elastomer (OBPE) inspired by Kirigami-like auxetic structure for stretchable sensing
