Colored Polyimide Film Matting Powder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for fabricating polyimide films require large amounts of matting agents and color additives to achieve low gloss and low transparency, leading to operational difficulties and poor dispersion, which are costly and inefficient.
Innovation Solution
A colored matting powder is developed by reacting diamine and dianhydride monomers at a substantially equal molar ratio, incorporating a pigment on the surface of polyimide particles, which is then used in the polyimide film to reduce gloss and enhance insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a large amount of color additive and matting agent are used to achieve low transparency and low gloss, then the desired optical properties are improved, but the operational difficulty and dispersion quality worsen
Solution Approach 1:
The patent combines the color additive and matting agent into a single integrated additive composition. This merged formulation allows both functions (coloration and matting) to be achieved simultaneously with reduced total additive quantity, improving ease of operation while maintaining the desired low transparency and low gloss properties.
Solution Approach 2:
The invention uses a composite additive system where color additives and matting agents are formulated together in specific ratios and configurations. This composite approach enables synergistic effects that reduce the overall amount of additives needed while achieving both coloration and surface matting functions, thereby improving operational ease and dispersion.
2Illumination intensity
If a large amount of color additive and matting agent are used to achieve low transparency and low gloss, then the desired optical properties are improved, but the dispersion quality worsens
Solution Approach 1:
By merging the color additive and matting agent into a single integrated composition with optimized ratios, the patent achieves uniform dispersion of both functions simultaneously. This combined approach prevents the aggregation and uneven distribution that occur when separate additives are used in large quantities, thereby improving manufacturing precision and dispersion quality while maintaining low gloss.
3Reliability
If conventional fabrication process is used with separate color additive and matting agent, then individual functions can be achieved, but the process complexity and cost increase
Solution Approach 1:
The patent creates a universal additive composition that performs multiple functions simultaneously: coloration, matting, and extinction. This multi-functional additive eliminates the need for separate processing steps for each function, reducing process complexity while maintaining reliable functional performance. The single additive system handles multiple objectives that would otherwise require separate treatments.
Solution Approach 2:
The invention merges multiple functional additives into a single integrated composition that can be added in one step. This consolidation reduces the number of processing steps, simplifies the fabrication process, and lowers costs while maintaining the reliability of individual functions through optimized formulation ratios and synergistic interactions between components.

AI summary
A colored matting powder includes particles containing a polyimide obtained by reacting diamine and dianhydride monomers at a substantially equal molar ratio, and a pigment incorporated with the polyimide, a portion of the pigment being located at an outer surface of the particles. Moreover, a colored polyimide film is also described as incorporating the colored matting powder, and can exhibit low gloss, low transparency and good insulation.
