The broader impact/commercial potential of this I-Corps project is the potential development of microencapsulation materials. Microplastics pollution is an environmental issue that has raised world-wide attention in recent years. Microencapsulated materials in some consumer products that are made from non-biodegradable materials are one possible source of microplastic pollution. The proposed technology microencapsulation technique may be suitable to encapsulate all oil-based materials in the liquid form such as fragrance oils and other ingredients that are used in laundry products, cosmetics, and agrochemical products, etc.This I-Corps project is based on the potential development of a microencapsulation technology that uses food grade natural polymers to potentially replace non-biodegradable microencapsulation materials currently being used in industry that may address part of the microplastics pollution issue. Microencapsulation techniques use a polymer layer to protect the cargo materials from being affected by environmental factors and subsequently release the cargo materials under designated conditions. Current commercially available techniques in consumer products mostly contain petroleum-based materials, which cannot degrade into small molecules in the natural environment after being used and can cause microplastic pollution. The proposed technology is a naturally derived material to potentially encapsulate oil-based materials in consumer products. The proposed technology microencapsulation method has a novel polymer structure that may combine the characteristics of a polyanion structure and an amphiphilic molecular structure that may allow the polymer to be concentrated at the oil-water interface to be crosslinked by the divalent metal ions to form the stable polymer film.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该I-Corps项目的更广泛的影响/商业潜力是微型塑料材料的潜在发展。微型塑料污染是一个环境问题，近年来一直在全球范围内关注。一些由非生物降解材料制成的消费产品中的微封装材料是微塑性污染的可能来源。所提出的技术微型塑料技术可能适用于以液体形式封装所有油性材料，例如香料油和其他用于洗衣产品，化妆品和农业化学产品等中使用的成分，等等。该I-Corps项目是基于潜在使用的微型材料来代替非生产力的材料的潜在开发的，该技术可能会替代非生物型的材料，这些材料可能会替代米牛油的杂物，这些材料是替代型号的生产量，该材料的构造是构成生产的杂物。微塑料污染问题。微囊泡技术使用聚合物层来保护货物材料免受环境因素影响，然后在指定条件下释放货物材料。消费产品中的当前市售技术大多含有基于石油的材料，该材料在被使用后无法在自然环境中降解成小分子并可能引起微塑性污染。提出的技术是一种自然衍生的材料，可在消费产品中可能封装油基材料。所提出的技术微囊化方法具有一种新型的聚合物结构，可以结合多娃娃奶酪结构的特征和两亲性分子结构，可能使聚合物可以集中在油水界面上，可以通过分隔金属离子来交联的油水界面。和更广泛的影响审查标准。
