摘要:Various embodiments provide random copolyimides that may possess the mechanical, thermal, chemical and optical properties associated with polyimides yet achieve a low energy surface. In various embodiments, the copolyimides may be prepared using a minor amounts of a diamino terminated fluorinated alkyl ether oligomer and a diamino terminated siloxane oligomer. The various embodiments include processes for making the copolyimides containing fluorine and silicon surface modifying agents and anisotropic coatings and articles of manufacture from them. Thus the coatings and articles of manufacture made with the copolyimides of the various embodiments may be characterized as having an anisotropic fluorine and silicon composition and low surface energy.

摘要:Various embodiments provide epoxy modified fluorinated urethane compositions that may provide desirable bulk mechanical properties of conventional coatings, adhesives, or structural matrix resins, while simultaneously exhibiting surface properties that may reduce surface contamination. Various embodiments provide formulations comprising epoxy modified fluorinated alkyl ether including urethane oligomer or polymer resins that may possess the requisite thermal, mechanical, chemical, and optical properties while achieving a low surface energy. In various embodiments, such resins may be prepared from random urethane oligomer compositions including fluorinated alkyl ether segments, in which the oligomers may be terminated with amino groups and subsequently reacted with epoxy including monomers or oligomers.

摘要:Disclosed in the present invention are a polyimide precursor and a synthetic method therefor, and a photosensitive resin composition comprising the polyimide precursor. The synthesis method comprises: in a solvent, reacting a dianhydride, an alcohol having a free radical polymerizable unsaturated double bond, and a side-chain modifier under the catalysis of a basic catalyst; adding a dehydration condensation agent thereto, and stirring the mixture; adding a diamine thereto for reaction, finally adding an end-capping agent to quench the reaction, and filtering the mixture; and adding the filtrate to a poor solvent within 0-2 h, precipitating a solid polyimide precursor resin, and refrigerating same, wherein the side-chain modifier is selected from any one or more of an alcohol side-chain modifier, an ether alcohol side-chain modifier and an amine side-chain modifier; and the end-capping agent is selected from any one or more of an alcohol end-capping agent, an ether alcohol end-capping agent and an amine end-capping agent. On the basis of not changing the main structure of the polyimide precursor, the present invention improves the dissolvability of the functional resin, controls the dissolution rate thereof, and ensures the performance of the final polyimide film after the functional resin has been heated and cured.

摘要:The present disclosure provides a method for producing an aerogel, the method comprising reacting at least one acid monomer with at least one diamino monomer in a first solvent under conditions appropriate to form a polyimide polymer; conducting a solvent exchange wherein the first solvent is exchanged for a second solvent, said second solvent having a freezing point, wherein said solvent exchange further comprises (1) submersing the polyimide polymer in the second solvent in a pressure vessel and (2) creating a high pressure environment inside the pressure vessel for a first period of time; cooling the polyimide polymer to a first temperature below the freezing point of the second solvent; and subjecting cooled polyimide polymer to a first vacuum for a second period of time at a second temperature.
