The present disclosure provides methods for stabilizing a colloidal dispersion during transport for low defect tolerance applications. The methods involve eliminating fluid interfaces within a dispersion, storing the dispersion in an environment of inert gas, and degassing the dispersion. Several bottle closure devices are described which may be ideal for use with these methods, being able to seal a container filled with a dispersion, permit the removal of headspace and rapidly empty the contained dispersion. In one aspect, the device includes a vented cap and semi-permeable membrane, which allows the passage of gas into and out of the container, and a dispenser nozzle integrated with the device to allow a stored dispersion to be dispensed without removing the device from the container. In another aspect, the bottle closure device includes an attachment point for a removable downtube and dispenser nozzle.

Disclosed is a method for mechanically anchoring polymers on the surface of a porous substrate by trapping polymer chains within the pores of the substrate under capillary forces. Surface modification of the porous substrate is achieved by anchoring one end of the polymer chains within the pores while one or more other ends of the polymer chains dangle from the surface of the porous substrate. The method provides a unique way of modifying the surface of a material without chemical reactions or precursor-substrate interactions.
