Lignocellulosic composites with grafted polystyrene interfaces

Investigation of unsaturated polyester composites reinforced by aspen high‐yield pulp fibers

“…Equation 3 was fitted to the measured tensile moduli of the low‐void content composites fabricated by the press process using the method of least squares. A fiber modulus of 26.2 GPa was obtained, very close to the values obtained by Cai et al and Neagu et al, 25 and 28.1 GPa, respectively [17, 23]. The experimental values (press process) were predicted quite well by the fitted curve.…”

“…Increasing fiber length had a positive effect on composite tensile and flexural moduli but resulted in lower water absorption resistance. Cai et al [17] studied the effect of grafting styrene onto CTMP fibers on the properties of CTMP fiber/polystyrene composites. The HYP fiber was mixed with the polystyrene in a brabender mixer, and the composites were made by compression or injection molding process.…”

Upgrading poly(butylene succinate)/wood fiber composites by esterified lignin

“…For example, Migneault et al [11] prepared high-density polyethylene/CTMP fiber composites using three kinds of CTMP fiber with different lengths, distributions, and aspect ratios and found that the mechanical properties increased with the increase in fiber length. Cai et al [12] reported the evaluation of composite of PS compounded with surface-grafted CTMP fibers. The results demonstrated that the grafted fibers exhibited higher fiber-matrix interactions than that of untreated fibers, and resulted in an obvious increase in mechanical properties.…”

Controlled grafting of cellulose diacetate

“…First, the grafting can be performed in heterogeneous system, i.e. on the surface of cellulose fibers or particles, giving surface-modified cellulose, which could be used, for instance, as a filler in appropriate polymer composites [17,18]. Thus, cellulose fibers (filter paper) were in the first step surface-acylated with 2-bromoisobutyryl bromide [19], giving the fibers with chemically anchored initiating sites, which were subsequently used for ATRP grafting of methyl acrylate (MA).…”
