A coated tubular construct for biological and industrial applications includes a plurality of channels, where each channel is radially surrounded by a wall comprising a first polymer, and a conformal coating comprising a second polymer is disposed on an outer and/or an inner surface of each wall. A method of producing a tubular construct includes 3D printing a template structure comprising a sacrificial material and a photoinitiator, and immersing the template structure in a first prepolymer solution comprising a first prepolymer and a co-initiator. During the immersion, the template structure is exposed to light, and the first prepolymer undergoes radical polymerization to conformally coat the template structure with the first polymer, forming a coated template. The sacrificial material is removed from the coated template, and a tubular construct comprising the first polymer is formed.

A thermoset resin for forming parts to be metal plated includes a vat photopolymerization (VPP) thermoset resin and an etchable phase disposed in the VPP thermoset resin. The etchable phase is etched from a surface of a part formed from the VPP thermoset resin such that a plurality of micro-mechanical locking sites is formed on the surface of the part. The etchable phase is at least one of organic particles, organic resins, inorganic particles, and copolymers of the VPP thermoset resin. For example, the etchable phase can be a polybutadiene phase and/or a mineral such as calcium carbonate.

The present invention relates to a method for producing a polymer, polymers and metal-polymer composites produced by the method. The method comprises providing one or more polymerisable monomers and providing a substrate comprising an activated metal surface, the activated metal surface comprising one or more compounds capable of initiating polymerisation of the one or more polymerisable monomers. The method comprises contacting the activated metal surface and the one or more polymerisable monomers to polymerise the one or more polymerisable monomers, thereby producing the polymer.

Novel stress-reducing crosslinking oligomers that have application in dental restoratives, thin films, hardcoats, composites, adhesives, and other uses subject to stress reduction are described. The addition-fragmentation process of crosslinking results in a chain-transfer event that provides novel polymers that may be further functionalized. In addition, the addition-fragmentation oligomer comprises pendent functional groups that bond to a substrate by forming an ionic or covalent bond, or etch the substrate by chemically removing some material from the substrate.
