摘要： Novel coatings disclosed herein can be used to mitigate dust adhesion. In one embodiment, a method of making a dust repellant coating includes combining a titanium dioxide sol with colloidal silica to form a mixture. The method also includes adding solvent to the mixture, stirring the mixture for about an hour, and filtering the mixture into a solution of titanium dioxide and silicon dioxide.

摘要： The disclosure relates to epoxidized lignin prepolymers, related methods of making the prepolymers, cured epoxy resins formed from the prepolymers, articles including a coating of the cured epoxy resins, and related curing methods and compositions. The epoxidized lignin prepolymer has an epoxide functionality in a range of 2 to 8 and a high solubility in various common organic solvents. The high solubility permits incorporation of the epoxidized lignin prepolymer into an epoxy system which cures after addition of curing agents at high enough concentrations to allow replacement of conventional epoxide prepolymers at levels up to 100% replacement. Using other biobased materials in addition to lignin, for example biobased epichlorohydrin to epoxidize the lignin and a biobased hardener to cure the prepolymer, can provide a corresponding cured epoxy resin that is formed from completely biobased materials.

摘要： Methods of embedding particles (e.g., nanoparticles) in a coating, the methods including contacting a first surface of a particle layer with a curable resin, followed by curing the curable resin to form a coating having a first coating surface and an opposing second coating surface, resulting in the particles being concentrated at the first coating surface. Also provided are applications for materials prepared according to the disclosed methods in, for example, hardcoating and nano-replication via reactive ion etching.

摘要： The present invention relates to methods for modifying the surface of engine components. In particular, the present invention relates to methods for binding surface modifiers to engine components coated with diamond-like carbon. The resulting engine components are particularly suitable for use in reducing friction and/or wear and/or in reducing fouling.

摘要： 과산화칼슘을 이용한 카테콜아민 코팅 방법 및 이를 이용한 저-결합 세포 배양 플레이트 제조방법에 관한 것으로, 구체적으로는 과산화칼슘(CaO 2 )이 첨가된 카테콜아민 용액에 코팅하고자 하는 기재를 침지시키는 단계를 포함하는 카테콜아민 코팅 방법 및 상기 방법에 의하여 카테콜아민이 코팅된 기재를 아민-반응성 PEG(mPEG) 용액에 침지시키는 단계를 포함하는 저-결합 세포 배양 플레이트 제조방법에 관한 것이다. 본 발명에서는 산소 공급 시약으로서 과산화칼슘을 이용한 생체 적합 물질의 표면 개질 기술을 개발하였다. 상기 과산화칼슘을 통한 산소 공급은 DA(dopamine hydrochloride) 산화를 촉진하여 신속하게 아민이 풍부한 기질을 생성하였으며, 간단한 침지 공정으로 저-결합 배양 플레이트를 제조할 수 있었으며, 상기 저-결합 배양 플레이트에서 배양된 세포는 다른 배양 플레이트에 비하여 보다 크고 컴팩트한 세포 스페로이드를 형성하였다.

摘要： The present invention refers to an improved method for applying silane-based coatings to solid surfaces, in particular metal surfaces, wherein a solid surface, in particular an optionally anodized or conversion-coated metal surface, is i) optionally cleaned, etched and/or desmutted, ii) brought into contact with at least one unhydrolyzed silane such that an unhydrolyzed silane layer is formed on the solid surface, iii) brought into contact with water such that the silane layer is at least partially hydrolyzed, iv) at least partially dried such that residues of water and alkanol are at least partially removed from the solid surface, v) optionally heated such that the at least partially hydrolyzed and least partially dried silane layer is cured, and vi) in case that step v) is conducted, optionally painted. The present invention also relates to an according silane-containing composition as well as to a solidsurface, in particular a metal surface, with an according silane-based coating and its use in the field of transportation industry or electrically conductive assembling.
