Problem
Conventional radiographic film commonly relies on petroleum-derived base materials, creating environmental concerns while still requiring long-term stability, moisture resistance, and sufficient mechanical strength for handling.
Why it matters
Film-based radiography remains in use, including in dental settings, despite the spread of digital imaging. A partially bio-derived film could reduce reliance on petroleum-based inputs if imaging and handling requirements are met.
Approach
The film combines acid-hydrolyzed palm mesocarp, starch, cellulose and nanocellulose, a synthetic polymer, plant hydrogels, cyanoacrylate adhesive, glycerin, and a Jamun-derived X-ray-sensitive dye. The method blends, pressure-heats, acid-treats, compounds, cures, and dries the mixture under specified conditions.
Who may benefit
Potential beneficiaries include radiographic-film and dental-imaging suppliers, specialty-film manufacturers, biomaterials researchers, and palm-processing organizations seeking higher-value uses for plant material.
Potential value
The disclosure offers a defined route to an X-ray-sensitive film with substantial plant-derived content and claimed mechanical, low-water-absorption, carbonate, and crack-resistance properties, while retaining a synthetic-polymer component.
Background
Background
Medical and dental facilities continue to use conventional X-ray film for some examinations. Such films typically rely on a petroleum-derived polyester base that supports the photosensitive layer during processing, storage, and handling. Replacing part of that structure with biological feedstocks requires more than simply using plant matter: the finished film must remain dimensionally stable, resist heat and moisture, and avoid tearing or cracking. The patent addresses this combination of environmental and material-performance needs through palm-derived nanocellulose, plant hydrogels, and a plant-derived sensitive dye.
Technology overview
Technology overview
Palm mesocarp is blended with water, heated, and hydrolyzed with an inorganic acid to generate a nanocellulose-containing mixture. Starch, cellulose, polyvinyl chloride in some embodiments, aloe-vera/okra/Acacia hydrogels, cyanoacrylate, glycerin, and Jamun dye are added before curing at 125–175 °C and drying at 60–100 °C. The claimed film contains 32.5–45 wt.% cellulose and specified ranges for tensile, water-absorption, carbonate, and crack-test properties.
Potential applications

Development stage
Development stage
Film preparation and mechanical, water-absorption, and crack-testing properties are described; commercialization was not established.
Commercial opportunity
Commercial opportunity
The formulation may interest specialty-film, dental-imaging, and biomaterials manufacturers exploring lower-petroleum product lines. Before product development, the X-ray sensitivity, image quality, processing compatibility, shelf life, and regulatory requirements would need direct validation. Compatibility with existing film processors would also need assessment.
