Three series of silicone modified polyurethane acrylate (SPUA) prepolymers were prepared from dicyclohexylmethane-4, 4′-diisocyanate (HMDI), PPG1000, triethylene glycol (TEG), 2-hydroxyethyl acrylate (HEA), and multi-hydroxyalkyl silicone (MI-III) with tris(trimethylsiloxy)silyl propyl side groups. Their structures were confirmed by 1H NMR, 13C NMR, and Fourier transformed infrared (FTIR) analysis, and SPUA films were obtained by UV curing. The properties of films were investigated by attenuated total reflection (ATR)-FTIR, scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), water contact angle (WCA), thermogravimetric analysis (TGA), differential scanning calorimeter (DSC), water and hexane resistance, and tensile testing. The results showed that the structures and dosages of MI-III could influence the polymerization properties, surface properties, water and n-hexane resistance, and thermal and tensile properties of SPUA. For instance, the surface aggregation of tris(trimethylsiloxy)silyl propyl groups (even ~2.5 wt%) could endow SPUA films with less microphase separation, good hydrophobicity, lipophilicity, thermal stability, and mechanical properties. Interestingly, obvious regular winkles appeared on the surfaces of SPUAIII films, which are characterized by relatively high WCA values. However, relatively smooth were observed on the surfaces of SPUAIII films, which also exhibit lower water absorption ratio values. Furthermore, the ordinary cotton textiles would be transformed into hydrophobic and oleophilic textiles after treating with SPUA simply, and they were used in the oil/water separation study. Among them, consistent with water and hexane resistance analysis of SPUA films, SPUAII treated cotton textiles are characterized by relatively small liquid absorption capacity (LAC) values. Thus, phenyl groups and side-chain tris(trimethylsiloxy)silyl propyl groups are helpful to improve the hydrophobicity and lipophilicity of SPUA films. SPUAII-5 (even with 5 wt% MII) treated cotton textiles could efficiently separate the oil/water mixture, such as n-hexane, cyclohexane, or methylbenzene with water. Thus, this material has great potential in the application of hydrophobic treatment, oil/water separation, and industrial sewage emissions, among others.

Abstract The present work detailsabout the low temperature curingbehaviour of bio-benzoxazine (C-ddm) prepared using cardanol and diaminodiphenylmethane (ddm)in the presence of polyaniline (PANI). Interestingly, it was found that the curing temperature (Tp) of the benzoxazine monomer (C-ddm) has significantly reduced to 227 ºC from 271 ºC with the incorporation of 2wt% of PANI. The plausible curing mechanism of benzoxazine ring catalysed by PANI was also discussed. Further, the resulted PANI/poly(C-ddm) matrices possessa marginally improvedvalues of glass transisition temperature and char yield. Further, PANI/poly(C-ddm) coated cotton fabric was studied for its UV shielding and surface properties. Furthermore, the UV shielding and surface behaviours of PANI/poly(C-ddm) coated cotton fabrics were explored. The PANI/poly(C-ddm) coated cotton fabric delivered UPF rating as high as 50 + and water contact angle value of162°. In addition, the PANI/poly(C-ddm) coated cotton fabric wasverified for its oil-water separation behavior. It was observed that the PANI/poly(C-ddm) coated cotton fabric offered97.5 % separation efficiency with enhanced flux value of about 6450 L/m2h flux.Thus, the obtained results suggest that the PANI/poly(C-ddm) can be used some of the industrial and environmental surface protection applications.
