A method of preparing tunable inorganic patterned nanofeatures by infiltration of a block copolymer scaffold having a plurality of self-assembled periodic polymer microdomains. The method may be used sequential infiltration synthesis (SIS), related to atomic layer deposition (ALD). The method includes selecting a metal precursor that is configured to selectively react with the copolymer unit defining the microdomain but is substantially non-reactive with another polymer unit of the copolymer. A tunable inorganic features is selectively formed on the microdomain to form a hybrid organic/inorganic composite material of the metal precursor and a co-reactant. The organic component may be optionally removed to obtain an inorganic feature s with patterned nanostructures defined by the configuration of the microdomain.

The invention relates to a hydrogel, in particular degradable or non degradable, comprising monomers of formula (I) and organosilica particles or porous silicon particles covalently bound thereto, optionally with non covalently bound organosilica and/or silicon particles mixed therewith, in particular degradable organosilica nanoparticles or core-shell nanocapsules; pharmaceutical, veterinary or cosmetic compositions thereof; and uses thereof as a medicament. The present invention finds applications in the therapeutic and diagnostic medical technical fields and also in cosmetic and veterinary technical fields.

The present invention relates to a method of forming silica nanolayers on or within a biological sample, thereby capturing structural details that are present in the sample. The resultant silica composite or silica replica, in turn, can be employed as a template for a replica having those structural details captured in a polymer. Also provided herein are synthetic constructs including a polymeric replica, which can have any useful feature (e.g., oxygen-binding capacity).

The present invention relates to the unexpected discovery of novel hybrid molecular brush (HMB) polymers and materials that are able to alter their characteristics based on the surrounding solvent properties. In certain embodiments, the HMBs are amphiphilic, comprising a backbone, at least one hydrophilic side-chain, and at least one hydrophobic side-chain. In another aspect, the invention relates to methods of making the HMBs of the invention.

Silica particles bonded to polymer chains consisting of at least one polymer comprising at least one fluorinated styrene repeating unit comprising at least one proton-conducting group, optionally in the form of a salt, the bonding between the particles and each of the chains being carried out by an organic spacer group.

The present disclosure is directed to a process for the preparation of resin-inorganic fibers composite and the obtained resin-inorganic fibers composite for coating. The process comprises the step of providing inorganic fibers bearing one or more monomer functional groups reactive with a monomer component; and reacting resin-forming monomer components with the inorganic fibers bearing one or more monomer functional groups reactive with a monomer component, to obtain the resin-inorganic fibers composite, wherein the resin is selected from the group consisting of alkyd resin, polyester resin and a combination thereof. The present disclosure is also directed to a coating composition containing the composite and a coating formed from the coating composition.

Organic-inorganic composite particles include: a vinyl polymer that is a polymer of a polymerizable vinyl monomer; and inorganic particles including inorganic oxide and/or inorganic nitride. The thermal conductivity of the inorganic particles is 10 W/(m.Math.K) or more. The inorganic particles are subjected to a surface treatment by acidic phosphoric acid ester having no polymerizable functional group, and by at least one polymerizable compound selected from the group consisting of: carboxylic acid having a polymerizable functional group; acidic phosphoric acid ester having a polymerizable functional group; and lactone having a polymerizable functional group. The polymerizable compound is bonded to the vinyl polymer, and the inorganic particles are unevenly located on surface layers of the organic-inorganic composite particles so that the inorganic particles form one or more layers.
