Firstly, economical, environmentally friendly, safe, and efficient functional materials can be developed to
reduce the production cost of leather composites and promote their faster application from the source.
Secondly, it is necessary to strengthen the stability and durability of leather collagen fibers combined with
functional materials, maintaining the breathability and comfort of leather to ensure the stable performance
and advantages of leather composites during the application process. Thirdly, the preparation process of
leather composites should be improved. The filtration, spraying, in-situ growth, and other methods of the
leather-making process should be industrialized, mechanized, and simplified so that intelligent leather
composites can embark on the path of industrialization. Fourthly, specific performance in the application
direction can be further deepened. Intelligent leather, such as conductive leather, flame-retardant leather,
and electromagnetic shielding leather, should be developed toward similar industry standards, and a
