1Strength

If organic hybrid materials are manufactured with inorganic nanostructures and organic polymers, then unusual properties such as high modulus and high toughness are achieved, but poor dispersion and miscibility between the components occur

Engineering Contradiction:
Improvemechanical modulusVSAvoiddispersion
Core Design Contradiction:
StrengthVSStability of the object's composition

Solution Approach 1:

The patent applies local quality by creating a core-shell structure where the inorganic nanoparticle core provides mechanical strength while the organic polymer corona provides dispersion stability. Different regions of the hybrid material have different properties optimized for their specific functions: the core for structural integrity and the corona for compatibility and dispersion in the matrix.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent uses composite materials by combining inorganic nanoparticle cores with organic polymer coronas to create hybrid materials that exhibit both the mechanical properties of inorganic materials and the processability and dispersion characteristics of organic materials. This composite structure resolves the contradiction between strength and dispersion.

Inventive Principle:
Principle #40Composite materials

2Object-affected harmful factors

If organic hybrid materials are manufactured with inorganic nanostructures and organic polymers, then inherent flame retardance is achieved, but poor interfacial strength between components occurs

Engineering Contradiction:
Improveflame retardanceVSAvoidinterfacial strength
Core Design Contradiction:
Object-affected harmful factorsVSStrength

Solution Approach 1:

The patent merges the inorganic nanoparticle core with the organic polymer corona into a single integrated hybrid structure. This merging ensures strong interfacial bonding between the two components, eliminating the interfacial strength problem while maintaining the flame retardance property that arises from the combination of inorganic and organic phases.

Inventive Principle:
Principle #5Merging (Combining)

3Object-affected harmful factors

If inorganic nanoparticles are dispersed in organic polymers, then enhanced gas barrier properties are achieved, but poor dispersion and miscibility occur

Engineering Contradiction:
Improvegas barrier propertiesVSAvoidmiscibility
Core Design Contradiction:
Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The patent applies local quality by assigning different functional roles to different parts of the hybrid structure: the inorganic core provides gas barrier properties while the organic corona provides miscibility and dispersion stability. This localized functional assignment allows the material to simultaneously achieve enhanced gas barrier properties and good miscibility.

Inventive Principle:
Principle #3Local quality
