Study on the Preparation Mechanism of Natural Bamboo-based Transparent Materials
In recent years,excessive logging and climate change have led to a gradual decline in available wood resources.Due to the structural differences in the components of bamboo and wood,substituting bamboo for wood in the preparation of transparent materials explores optimal processes for producing high transparency and strength bamboo-based materials after delignification and epoxy resin impregnation.Efficient utilization of bamboo is expected to significantly alleviate the shortage of wood resources.This study employed orthogonal ex-periments to analyze the effects of processing time(A),bamboo chip thickness(B),and sodium chlorite mass fraction(C)on delignification and the properties of bamboo-based transparent materials.Experimental results indicate that the best performance of bamboo-based transparent materials is achieved under conditions of 6 hours of processing time,bamboo chip thickness of 0.8 mm to 1.0 mm,and sodium chlorite mass fraction of 4%,yielding a maximum light transmittance of 35.14%and haze of 94.79%.This study provides a simple and ef-fective method for preparing natural bamboo-based transparent materials,which exhibit sustainability,environ-mental friendliness,and high performance,reducing reliance on traditional plastics and glass and realizing the concept of"bamboo instead of plastic".
