CONVERSION OF CELLULOSIC FIBERS INTO “STICKYSUPERHYDROPHOBIC PAPER INVOLVING THE USE OF MICROSIZED MINERAL PARTICLES AND ROSIN VIA INTERNAL/SURFACE ENGINEERING
The unique features of cellulosic paper including flexibility,biodegradability,and low cost enables it as a versatile biomaterial for promising applications.In the paper industry,microsized mineral particles are widely used in the production of printing/writing paper grades,while rosin derived from coniferous trees is the earliest internal sizing agent for paper hydrophobication.On the basis of existing commercial practices associated with the use of fillers/pigments and rosin in paper production,we present a process concept of converting cellulosic fibers(paper grade pulp)into “sticky superhydrophobic paper involving the use of microsized mineral particles and rosin.Internal filling of cellulosic networks with mineral particles was basically used to hold out the mineral particles added at the surface,and the delicate integration of wet-end/surface applications of mineral particles with paper surface engineering with rosin/alum led to the development of “sticky superhydrophobicity,i.e.,ultrahigh water-repellency and strong adhesion to water.This proposed concept may provide valuable implications for expanding the use of paper-based products to unconventional applications,e.g.,ultrahigh-performance ink jet printing paper for mitigating the “coffee-ring effect and paper-based microfluidic devices for biomedical testing.
