Mechanism research on the application of liquid film microencapsulation technology based on natural lotion in strengthening recycled bio‐composite wallpaper material

Abstract

AbstractLow‐carbon technology is currently one of the main research directions in sustainable research. The purpose of this research is to explore environmentally friendly low‐carbon technologies to apply NL and wastes to the development of bio‐composite. This research can not only inhibit the release of toxic atmosphere from composite wallpaper materials but also propose new perspective for recycling several bulk wastes such as agricultural waste, waste plastics, and waste cooking oil. This study not only conducted an exploratory research on the degree of filling load from a vertical perspective but also conducted comparative experiments to clarify the strengthening effect of NL in a horizontal perspective. Several valuable findings are obtained through the analysis of several measurements such as mechanical performance and scanning electron microscope (SEM) morphology. The heat transfer effect between components inside the bio‐composite is enhanced by the action of NL. A better heat transfer effect can prevent heat from accumulating in local areas of bio‐composite, resulting in an increase in the overall initial pyrolysis temperature of thermogravimetric analysis (TGA) curve. It is found through experiments that when the biomass filler is excessive, the mechanical performance of the sample sharply decreased. These negative phenomena are presented in the specific form of voids and aggregates in the internal structure of bio‐composite from a microscopic perspective. Comprehensive analysis manifested that NL can suppress the negative effect of filler agglomeration and strengthen the filler/matrix interface bonding. The research also found that the type of biomass filler can affect the actual effect of NL. These findings have certain academic significance and can promote the further development of sustainable research on diversified recycle of wastes.
