  • Patent number: 11173649
    Abstract: Embodiments relate to a method of fabricating a nano-sized structure in a resin element by nanoimprint lithography (NIL). The method reduces adhesive failure during NIL demolding by inhibiting polymerization at the interface between the resin element and the template. The template includes a polymerization inhibiting compound. The method includes pressing the template onto the resin element (or the resin element onto the template) to form the nano-sized structure in the resin element. The method also including diffusing the polymerization inhibiting compound from the template to the resin element, e.g., by holding them together for a period of time. A layer of the polymerization inhibiting compound is therefore formed at an interface of the template and resin element. The polymerization inhibiting compound inhibits polymerization at the interface. After the diffusion, the resin element is cured. Then the template is removed from the resin element.

  • Publication number: 20130131357
    Abstract: The invention relates to a method for preparing silica modified by a silane coupling agent. The method comprises the following steps: preparing a kind of coupling agent sol solution by mixing the solvent, water, catalyst and coupling agent; uniformly dispersing silica into the sol solution by means of ultrasonic dispersion or shear dispersion to achieve a turbid solution with uniform dispersion and ideal particle size; and then stirring the turbid solution at a constant speed to make the coupling agent sol reacting with silica to prepare highly hydrophobic silica modified by the coupling agent through controlling the temperature and reaction time. The coupling agent sol solution is obtained by a sol-gel process and silica is uniformly dispersed in the coupling agent sol solution through combined action of various dynamic means to ensure the sufficient reaction between silica and coupling agent, thus to obtain silica modified by the coupling agent.

  • Publication number: 20130059987
    Abstract: Inorganic particulate or whiskers are surface-treated to facilitate receptivity to covalent bonding with a coupling agent. Surface treatment forms reactive groups that enable the inorganic particulate or whiskers to covalently bond to a reactive group of the coupling agent. The coupling agent also contains organofunctional groups, which in some examples may be covalently bonded to a polymer matrix by way of crosslinking or by co-polymerizing the functionalized particulate or whiskers together with polymer precursors. The resulting polymeric materials exhibit markedly improved abrasion resistance as well as other improved properties.
